Weight gain at three months. Normal weight gain of a newborn during the year. How to calculate the proper weight of the child

Perhaps the most important indicators of a child at birth are the length and weight of his body: these values ​​\u200b\u200bare the first entries in the first baby documents: a medical card and a tag. How much these parameters should change in 12 months will help you find out the table of height and weight of children up to a year.

Norms of weight and height in newborns

For babies born at term (from 38 to 42 weeks), the range of 46-57 cm is considered normal height, and weight - 2600-4000g. If the baby is premature, or born with pathologies, as well as in the case of multiple pregnancy, these figures can be significantly lower. So, for twins and triplets, weight up to 2 kg is also not considered critical.

When the baby is discharged from the hospital, he weighs a little less than at birth, and this is also the norm: in the first days, up to 8% of the weight is lost. But only when the weight stops falling and begins to increase, the baby is ready for discharge. The increase in height and weight of newborns is monitored by a pediatrician, which is why it is so important to visit him every month.

Increase in height and weight of crumbs up to a year

For the first six months, the baby adds 500-800g monthly on average. And every month at the pediatrician's appointment, the ruler shows from 2 to 5 cm of growth.

In the second half of the year, the rate of weight gain slows down as the child becomes more active.

During the year, the baby grows by an average of 25 cm, and the weight increases approximately three times.

centile tables

It is much more accurate to assess whether the development of the baby is harmonious, centile tables help.
The columns of the tables contain quantitative limits for weight and height indicators for a certain percentage of infants; averages are considered to be intervals from 25% to 75%.
If the parameters of your baby fit into these intervals, then this can be called the norm. Columns before and after these corridors (10%-25%) and (75%-90%) are considered as deviations from the norm in the smaller and larger sides, respectively. If the baby’s indicators are included in the most extreme columns, this is an occasion for an urgent appeal to specialists.

It is very important that both the height and weight of the child are included in one centile corridor (+/- one column), such a “height-weight” ratio is considered correct. To do this, compare the data that the child's growth table shows by months up to a year with the data from the baby's weight table up to a year, and evaluate the result.

How to measure height and weight correctly?

Sometimes the wrong measurement of height and weight causes young mothers and fathers to panic. And sometimes even the doctors themselves are mistaken: the baby slipped a little on the stadiometer, or did not straighten the leg to the end - and here it is, the error! They forgot to take away the weight of the diaper when weighing in the previous month - so the weight loss came out next!

You need to measure the weight and length of the body regularly and write it down on a tablet for up to a year by months (you can do it yourself), such records will help you independently assess whether your baby is developing correctly.

To measure your baby's height at home, prepare a pencil and a large wooden ruler or measuring tape. It is better if the baby is naked: a cap and socks can give an error in measurements, and even a diaper, due to its rather big, in general, thickness, raises the baby’s ass, the back bends slightly, which can also cause inaccuracies.

Place the baby on a hard surface (ideally a changing table) so that the head rests on a hard barrier perpendicular to the surface: the side of the table, the head of the bed, the wall. Stretch the legs, straightening them at the knees. Mark a line under the heels (not fingers!). Measure the distance from the headboard to the dash.

Scales are needed to measure body weight. In general, it is very useful to purchase them as dowry crumbs. Scales need special, children's, electronic, with a convenient bowl.

Undress the little one. Put a thin diaper on the scales, drop its weight so that the scoreboard shows zero. Place your child on the scale, distributing the weight evenly on the bowl. Wait until the numbers stop motionless.

Never use a steelyard scale while placing your baby in a bag or tied diaper for measurements. This method of measurement is very dangerous, you can drop the child. And it's still not possible to achieve the exact result.

Do not be discouraged if the weight and height of the baby do not reach the average table! It is important that they match each other. And if the child is too small or too large, take a closer look at yourself: maybe he went to dad or mom?

Weight gain and height in newborns and children up to a year

All parents compare their children with their peers. After birth, parents worry about newborn weight gain, often without knowing what the norms are. In the children's clinic, the child is weighed and measured for height, as well as measuring the circumference of the head. All these data inform the doctor about the development and nutrition of the child.

Newborns - that is, children from birth to 28 days in the first days of their stay in the hospital lose weight. And do not be surprised that weighing at discharge will show minus 200 g. But between the seventh and tenth day of life, weight loss is compensated. By drinking more and more milk each time, the stomach of the newborn is stretched.

In the first two or three months, the child intensively gains weight, every day it becomes more by 25-50 g. Up to six months, this figure drops to 18-20 g. per day, and in the eighth and ninth months, the weight is added every day already by 15-18 d. A baby weighs three times its birth weight per year.

If it is difficult to measure the weight of a child every day, then the norms of weight gain in newborns and children up to a year in the first weeks of life are 180-300 g per week.

As for the growth rates of children, girls are more likely to be born less than a centimeter of boys. Boys are about 50 cm and girls are 49 cm, but the range from 47.5 cm to 53 cm is considered normal. In the first three months, the baby increases by 10 cm, the next three months give an increase of 6.5 cm. Until the ninth month, the child will add another 4.5 cm, and from the ninth to the twelfth month - 4 cm. By the year, the boy's height is about 75 cm, and girls are 74 cm. But this is not the gold standard, of course, the baby can be lower or higher.

Many factors influence the height and weight of a newborn and a child up to a year old: race, genetic predisposition, activity of the child, infectious diseases, nutrition.

In the above tables of weight gain and height in infants and children up to a year the average rate is described, as well as the possible range. In order to know if everything is in order with the child, it is better to show it to a specialist, and not discuss it on the bench with other mothers. Responsibility for the health of the baby lies only on the shoulders of the parents. If there is no trust in the local pediatrician, then in our time you can consult with other pediatricians.

More often, children with health problems add little. Or little weight gain in babies accompanied by a small amount of milk from the mother. Those women who are breastfeeding fanatics. and there is little milk in the chest, they reach the point that the child is forever hungry hanging on his chest for days on end.

If the baby does not gain weight, he cries all the time because of hunger, is lethargic, does not poop for several days, because there is nothing. then you need to immediately go to the doctor and enter the mixture. A child should not starve, he does not have energy reserves, like adults, hunger can undermine the health of babies.

If there is enough milk, and the baby is not hungry, but does not gain the norm, then the mother should calm down and look at the child. If the baby is active, he has a healthy skin color, he does not constantly ask for food, the child's parents are thin, then gaining 650 g for the baby instead of 800 g will be normal.

How much weight should a newborn baby gain

Weight gain in newborns is an important indicator of normal physical development. Immediately after the birth, the baby is examined by a pediatric neonatologist, writes down its parameters, checks for reactions, then the baby is placed in the mother's breast. The task of the doctor is to monitor how much your baby is gaining in weight and give recommendations on breastfeeding.
There is a special norm for weight gain in newborns, according to which all children under one year old will be checked monthly at the clinic, and from the first weeks, mothers need to know how the child should grow by months, how much weight to gain in order to avoid mistakes in feeding or correct them in time .

How much should a child weigh?

There is no exact concept of a standard weight for babies, everyone is born individually. The normal weight of a newborn is from 2700 to 4000 grams. Moreover, the indicators of the norms for girls and boys are slightly different. Usually the boy's weight is from 2900 to 4500 grams if the birth was on time. And the weight of the girl is from 2700 to 3900 grams, also subject to full-term.
The first couple of days of stay in the maternity hospital, a newborn usually loses from 40 to 100 grams, this is due to adaptation to life outside the mother's tummy, high energy costs for self-feeding, drying out of the umbilical cord. In addition, milk in women usually does not appear immediately after childbirth. When the nutrition of the crumbs returns to normal, a gradual increase will begin.

How quickly a baby gains weight is influenced by many reasons:

Genetic features of the baby's parents. If mom and dad are tall and full, most likely the baby will grow up as a rosy-cheeked strong man, and vice versa, if the parents were thin in childhood, the baby will probably be born small. type of feeding. If the mother is breastfeeding the baby, weight gain will occur evenly and within the normal range. When feeding with a mixture, an accelerated increase in body weight by months is often observed. The diet of a nursing mother. The volume of lactation may depend on the quality of food, their calorie content, taste properties, so some foods are harmful to eat while breastfeeding. Weight at birth. If the baby was born large, more than 4000 grams, most likely in the first few months he will add a little less than peers who weighed less than 3000 grams at birth and are actively replenishing their shortfall.

The greatest weight gain in newborns occurs in the first three months - 600-1500 grams per month. After all, the baby hardly moves, eats only breast milk or a mixture. From the fourth month, the child becomes more active, turns from the back to the side, to the tummy, weight gain slows down and normally amounts to 500-800 grams per month. From the sixth month, the introduction of complementary foods begins, the babies are actively moving, interested in the outside world, the average increase is already from 500 grams per month. From the ninth month to a year, the child gains on average about 400 grams, he actively moves, walks, crawls, most of the calories go to replenish energy.

Weight standards in numbers

Often, mothers meet the rate of weight gain in the form of a table. It displays the average monthly value for children from birth to two years old, and you should not blindly follow the data from it, comparing your baby with others. This table can be used when there is doubt about a large increase or a serious deviation from the typical values ​​​​down. Moreover, such deviations from the norm should not be ignored.

Reasons for underweight babies:

Lack of breast milk leads to a shortage of the required body weight in newborns. If your son or daughter often cries, sleeps little, screams, is naughty when breastfeeding, it is necessary to undergo a control weighing at the pediatrician's clinic, and if lactation is insufficient, adjust the feeding regimen or, if necessary, switch to mixed feeding. Improper breastfeeding can also lead to a small increase. You need to feed on demand, properly attach the baby to the breast and do not eat foods that are prohibited for nursing mothers. Overfeeding, on the contrary, leads to rapid and excessive weight gain. If a child is formula-fed for a number of reasons, do not dilute it more than what is written on the package. In this case, you need to feed after a certain time and the indicated dosage. Breast health problems. If he eats little, lethargic, sleepy, poorly gaining weight. make an appointment with the pediatrician and take the prescribed tests to identify the problem.

The most important thing is to visit the pediatrician regularly, follow all the pediatrician's recommendations for feeding and caring for the newborn, do not panic with small deviations from the standard norms and love your baby - then everything will turn out fine for you and your newborn.

Weight gain in babies

By the way an infant increases body weight, one can judge the state of his health. Weight gain in infants depends on many factors: the amount and nature of nutrition, the presence of congenital anomalies (heart defects, digestive system), hereditary intolerance to amino acids or lactose due to the lack of enzymes. Next, we will consider the norms of weight gain in infants, as well as in which cases the weight of the child may be more or less than the norm.

Monthly baby weight gain chart

WHO experts have developed norms for weight gain in infants by months, in which slight fluctuations are allowed. So, for example, tall parents give birth to large children, and they can gain more mass. And, accordingly, to small parents, children are born small and may recruit less than other children. The average newborn is born with a weight of 2650 to 4500 kg. And in the first week can lose up to 10% of body weight. On average, for the first six months, the baby gains 800 grams per month, which is displayed in the formula:

Body weight = birth weight (g) + 800*N, where N is the number of months.

Starting from the seventh month of life, weight gain decreases significantly and is determined by the following formula:

Body weight \u003d birth weight (g) + 800 * 6 (weight that the child gained in the first six months) + 400 * (N-6), where N is the number of months from 6 to 12.

However, pediatricians do not evaluate the child's body weight separately, but the ratio of weight to height (mass-height indicator), which gives reason to talk about the harmonious development of the child. The following is a table of the rate of increase in height and weight of infants who are.

Deviations in weight gain in infants

I would like to note right away that the birth of a large child (more than 4.5 kg) is possible for parents who have a tendency to increase blood sugar. And the birth of malnourished hypotrophic children speaks of fetoplacental insufficiency. intrauterine infection and anomalies of internal organs.

Weight gain in infants depends on the type of feeding. So, breastfed babies in most cases gain according to the table above, and artificial babies are usually larger than their peers. If the mother does not have enough milk or if it does not meet the proper composition, the baby may not gain enough weight. Too much weight gain in infants can indicate pathology of the cardiovascular, respiratory and endocrine systems.

How to determine that the baby is not gaining weight well?

Young mothers often cannot immediately determine that their baby does not have enough milk that is. To do this, you need to pay attention to the behavior of the child. If the baby is full, then he can sleep peacefully for up to 3 hours, and even if he is awake, he does not show irritation. A hungry baby falls asleep only for short periods of time, after which he wakes up and requires another feeding. A newborn baby should urinate up to 20 times a day, and recover 3-4 times. For the sake of experiment, you can try to weigh the baby before and after feeding. He should increase his weight by 60 grams.

Thus, we examined how much a newborn child should gain in the first year of life. If the baby is not gaining weight, then you should consult a pediatrician in order to determine the cause. If the cause of insufficient weight gain is hypogalactia, then the doctor will help you choose a good mixture and give recommendations on mixed feeding, as well as advise medicines to stimulate lactation.

You have a baby. You have been waiting for him for a long time, imagining what he will be like and how you will raise and educate him. But when it finally happens, you suddenly run into a lot of unforeseen problems. One of them, which never ceases to excite every young mother and all grandmothers in the world, is the rate of weight gain in newborns.

Normal weight for a newborn baby

"Reference point" of the weight of the newborn

Each newborn baby is examined by a pediatrician, and at the first examination, he is immediately weighed and measured for height (Newborn Growth). Then the child, together with his mother, will remain in the hospital for another 4-6 days to be monitored by doctors. On the day of discharge, he is weighed again. It is from these 2 numbers - the weight in the first minutes after birth and the weight on the day of discharge from the hospital - that the subsequent weight gain of the newborn begins and largely depends. So:

Baby's weight at birth

All babies are born with different heights and weights, and The normal weight of a healthy baby at birth is between 2,700 kg and 3,700 kg. It should be noted that the initial weight of the child depends on a number of different factors:

Baby health. Heredity. Mothers of high stature with high weight are more likely to give birth to large children, and vice versa: thin, short women give birth to small babies. Paul. As a rule, boys are always born larger (heavier) than girls. Maternal nutrition during pregnancy. With a high-calorie diet of a pregnant woman, the fetus usually gains a large mass. The physical and psychological state of a woman. If a mother is unwell or during pregnancy she lived in a state of stress for a long time, then this may well affect the health and, accordingly, the weight of her newborn child. Presence of bad habits in a pregnant woman. Of course, a smoker, and even more so a drinker and drug user, can give birth to sick children with insufficient weight.

Discharge weight

In the first few days of life, children lose some weight. Weight loss is due to several reasons:

Fluid loss. Once born, the baby begins to breathe, and a large amount of fluid escapes through its respiratory system and skin. Power installation. In the early days, the baby drinks colostrum, and in small portions, until he gets better nutrition, and his mother begins to receive milk. Adaptation to living conditions. We know perfectly well that the young seedlings transplanted by us from the greenhouse to the garden do not begin to grow immediately. Similarly, a child, having radically changed its habitat at birth, does not immediately get used to living in it.

Thus, discharge weight differs by about 6-10% from birth weight. And it is from this, second, number that it is customary to count the norms of weight gain for each newborn.

Weight gain rates

You and your baby were discharged from the hospital and you ended up at home. The kid has learned to eat, his digestion and heat-air exchange with the environment are gradually getting better, and he begins to grow rapidly.

Video: child's weight

Reasons for weight gain or lack thereof

Weight gain depends on the following reasons:

Health. If the baby is sick, he eats worse. Appetite. Type of feeding: breast or artificial. Formula-fed babies usually gain weight faster. The quality and quantity of food (mother's milk). Child mobility. A person involved in sports is usually fit. Similarly, an active child is somewhat thinner than a couch potato. Daily routine and meals. When feeding "by the clock" weight grows more slowly than "on demand". age. In the first months, children grow faster, by the year growth slows down.

Be that as it may, scientists-specialists have established some average conditional indicators of the norms of weight gain in newborns.

Increase rates: table of weight of a child up to a year

The average data shows that usually weight gain in the first year of life is as follows:

During the first month, when your baby is still very young, it is considered normal to gain weight by 90-150 grams per week. From the second, third and until the end of the fourth month, the baby should already gain 140-200 grams per week. From the fifth month to six months, the weight is added again by 100-160 grams per week, and by six months, your baby's weight should approximately double. Further, growth begins to slow down a little, and by one year the child weighs about 3 times more than it was at birth.

Deviations from the norm: is it worth worrying

Very often there are deviations from the above averages. This is too little or too much weight gain, which is also bad, because too fat guys become inactive and develop more slowly. In addition to possible diseases of the baby, the reasons for such deviations can be as follows:

Each person in his physiology is individual, and everyone grows differently: someone is a little faster, and the other is a little slower. The norms of weight gain in all newborns of greater height are usually greater. So, if for a baby whose initial height was 52 cm, an increase of 170 grams is considered normal, then for a child with an initial height of 58 cm, it is already about 210 grams. It often happens that boys gain weight faster than girls. With artificial nutrition, babies get fat faster.

And many other reasons, which are different in each case, and it is possible to identify them only with an individual approach. And only after identifying these reasons, it is possible to give an accurate answer whether parents should worry about this and whether to take urgent measures. In any case, the rates of weight gain in newborns are averaged and approximate, and should not be taken as an ideal. And if you have any doubts about the growth of the child, it is best to take tests and consult with specialists. If you and your baby are healthy, then perhaps for the appearance of rounded folds on his body, it is enough to start feeding him on demand, often applying him to the breast, and this will solve the problem.

Why is my child not gaining weight? Complementary feeding of infants

How to weigh a child

Every baby is born with a certain body weight. The norm is 2700 - 3700 kg. However, small deviations from these numbers do not yet say that the child is sick or something is wrong with him.

The weight of a newborn depends on:

health; heredity; gender; mother's nutrition during pregnancy; the physical and psychological state of the mother; the presence of a woman's bad habits;

The baby loses some weight in the first days after birth. This is due to the fact that the body loses a lot of fluid and adapts to the new environment. At discharge, the baby will weigh 6-10% less than at birth. It is from the second digit (at discharge) that they begin to count the indicators of weight gain.

Features of weight gain in newborns

In the first four weeks of life, the rate of weight gain in newborns is 90-150 grams in seven days. From the second to the fourth month, the child gains 140-200 grams per week. Then the increase drops to 100-160 gr.

Thus, by six months, the mass will double. Further, the set slows down, and by the year the newborn weighs about three times more than at birth.

Some children gain weight quickly, some slowly. Why is this happening? This is influenced by a number of factors:

Health; Appetite; Type of feeding (artificial or breastfeeding). With artificial feeding, weight is gained faster; Daily routine and meals. When feeding on demand, weight grows faster than when feeding by the hour; The quantity and quality of milk from the mother; Mobility and activity of the newborn.

Scientists have established conditional average rates of weight gain in children under the age of one year.

Average rates of increase

The table contains approximate figures for the weight gain of children under one year old. Remember that every baby is different and recruitment rates may vary from those shown.

Please note that a similar table was compiled for children who are on artificial feeding. With natural nutrition, the baby develops as nature intended. And the indicators in this case depend on genetics and compliance with the rules of feeding. However, the table will guide you and help you get an idea of ​​the formation of the mass of the child.

Keep in mind that the larger the baby, the faster the weight increases. So, a newborn with a height of 52 cm adds 170 grams, and a height of 58 cm - already 210.

How to calculate the proper weight of the baby

On average, for the first six months, weight gain in newborns is 800 grams, and after six months - 400. Therefore, to calculate the approximate weight of the child for this period, use the following formula:

Body weight of a child up to six months = weight at discharge + 800 x age (months)

For example, the baby was 4 months old, and he weighed 3000 grams after birth. Then the proper weight = 3000 + 800 x 4 = 6200 grams.

To determine the weight after 6 months, use the following formula:

Body weight of a child after six months = weight at discharge + increase for the first six months + 400 x (baby's age in a month - 6)

To calculate the addition for the first six months, then just 800 x 6 and we get 4800 grams. Use the finished figure to calculate the mass of an infant over six months old.

If the baby is 8 months old, and initially he weighed 2900 grams, then the proper weight \u003d 2900 + 4800 + 400 x (8-6) \u003d 2900 + 4800 + 800 \u003d 8500 grams.

Overshoot and Undershoot

Mom may face two problems - weight loss or overweight. If the child is not feeding, then, first of all, determine whether the feeding is taking place correctly. The baby should receive milk 10-12 times a day and stay at the breast for as long as he wants. The number of trips to the toilet also affects. Diapers should get wet at least 12 times a day.

In order for the baby to gain weight correctly, lactation should be adjusted:

Pay attention to night feedings. This is the most nutritious and high-calorie milk; Drink more fluids (drinking water, compotes, tea, natural juices); Attach the baby to the breast more often; Start introducing complementary foods with cereals.

Excess is also a problem. Unfortunately, many mothers worry only when the baby is not getting enough. However, the problem of overweight is also dangerous if the rate of increase does not decrease after six months, and the baby at 6 months corresponds to the parameters of a one-year-old. This may be due to genetics, but it will not be superfluous to seem to an endocrinologist. Excess weight can be the result of health problems.

If there are no problems, then excess weight can lead to diseases.

To avoid complications, follow a few recommendations:

Remove night feedings, as night milk is the most nutritious; Introduce complementary foods only with green vegetables. What vegetables can be eaten by a nursing mother read here Organize a swim every evening. Bathe the baby not in a baby bath, but in an adult bath; Do a general wellness massage; Watch the diet of a nursing mother. Avoid fatty, overly sweet and spicy foods.

Watch your baby's weight carefully. Remember that the table is conditional, each child develops individually. So don't panic if the numbers differ.

Most parents are interested in the physical health of their children. Indicators of weight and height of a child under 10 years old are its key parameters, both for girls and boys. The evaluation criterion is a special scale or auxiliary tables compiled by the World Health Organization. What values ​​will be optimal for different age periods of both sexes?

Measuring the physical child gives insight into the course of development

Development indicators of girls and boys in the first year of life

Weight by month

There is a separate table showing weight gain for babies up to a year old:

The norm and limits of deviation of the child's weight indicator in the first year of life

Height and weight of a child from one year to 10 years

Very low and high numbers indicate the presence of deviations, those that are in the range above and below the average belong to the variants of the norm.

The height and weight table for children under 10 years old is compiled separately for boys and separately for girls and will help you determine for yourself whether it is necessary to correct the process of physical development of your child.

Indicator table for boys

Taking into account the regular weight and height gain by young men, WHO compiled the following table of height and weight for boys under 10 years old:

Growth indicators of development of boys up to ten years

Weight indicators of the development of boys up to ten years

The table of height and weight of boys of 10 years old shows a proportional ratio for a given time period:

Indicator table for girls

Unlike boys, girls develop much faster. Therefore, do not be surprised that children of different sexes of the same age may be inferior in performance to each other. The height and weight of girls under 10 years old is presented in this diagram:

How do children grow from one to three?

The WHO table of average values ​​will help to track the timely increase in the required centimeters and kilograms:

2 years 3 months
2 years 6 months

Features of the development of children from 3 to 5 years

The physical development of a 3-5 year old child is determined by several parameters:

1. 3 years - height 96 cm +\- 4 cm, weight 12 kg +\-1 kg, chest circumference 51 cm +\-2 cm, head circumference 48 cm, the presence of about 20 milk teeth;
2. 4-5 years - 104 cm +\-4 cm, 17 kg +\-1 kg, chest 55 cm +\-2 cm, head 50 cm, teeth have not yet changed to permanent ones;
3. the skull of a three-year-old baby is equal to 80% of the volume of the skull of an adult, the spine is unstable, and the bones and joints are easily deformed from negative external influences;
4. very fast blood circulation corresponds to a pressure of 95 to 58, there is increased excitability, leading to rapid fatigue.

How do girls and boys grow up from 5 to 10 years old?

Starting from the age of 5, the child's body gradually transforms into adolescence. The norms of height and weight for children 10 years old, as well as in the primary school period, are:

• 6 years - the body becomes higher by 6-7 cm and heavier by 2.5-3 kg, the average height is 107-121 cm, weight 18-28 kg, chest girth 56-65 cm;
• 7 years old - another 8-10 cm in height are added, 2.5-3 cm to the chest, body length 114-128 cm, the baby weighs 20-30 kg;
• 8 years - changes characteristic of puberty are not yet noticeable, 21-32 kg and 119-134 cm;
• 9 years old - kids grow up to 125-140 cm and 24-36 kg, respectively;
• 10 years - averages - 129-146 cm and 25-39 kg.

For a simpler understanding of the development of the child, a table of height and weight of children of 10 years is given:

	boys
	Weight, kg	Height, cm	Weight, kg	Height, cm

“How did you gain 600 grams in a month?! This is very little! Your milk is bad. Let's mix!"

“1700 gr per month?! Do you want to get fat? You have too much too fat milk. Feed every 3 hours and give water. And better go to the mixture!”

Many mothers are familiar with these phrases during routine examinations in the first months. The thing is that until now, some doctors are guided by outdated growth standards for children, which did not take into account many factors that affect the development of the child. For example, the type of food.

The good news is that today there is WHO data obtained from the results of many years of observation of children who are breastfed.

Excerpts from the study description:

http://www.who.int/mediacentre/news/releases/2006/pr21/ru/

"...Children were selected to participate in the study, living in optimal conditions for proper growth (recommended feeding practices for infants and young children, good health care, non-smoking mothers and other factors associated with good health outcomes)..."

"... In the new norms based on indicators of growth and development of children who are breastfed. For the first time, the tools used to assess growth are aligned with national and international infant feeding guidelines recommending breastfeeding as the optimal source of nutrition in early childhood. This will allow you to accurately evaluate, measure and analyze the results of breastfeeding and complementary feeding ... "

WHO provides beautiful tables and graphs as results. Which can be difficult to understand :-). How can a mother understand if everything is fine. Let's figure it out together.

From birth to 2 weeks

In the first days of life, the baby usually loses weight. This is normal and is due to adaptation to a sharp change in habitat, the release of meconium (original feces), and the removal of excess fluid.

On average, losses range from 5 to 8% of birth weight. In some cases, losses up to 10% are possible. You don't have to do anything about it, it's physiological weight loss.

One of the main indicators for assessing the health status of a newborn baby is height, weight, head and chest circumference. The norms for the growth and weight gain of newborn children are established by the World Health Organization.

Many mothers are interested in how these indicators of the development of the baby change, whether the height and weight of their newborn child correspond to the norms.

Growth and weight standards for newborns

After the birth of a child, standard measurements are taken - height and weight.

Growth

The growth of a newborn baby is 45-54 cm. But more accurate measurements of the growth of a child are carried out 2-3 days after birth. This is due to the fact that during this time the degree of deformation of the bones of the skull and swelling of the soft tissues of the head decreases.

The body length (height) of a newborn baby depends on many factors. The main ones are heredity, the sex of the child, the state of the uteroplacental flow during pregnancy, the quality of the mother's nutrition.

There are certain patterns of growth of the newborn. Thus, the most intensive growth is observed in the first three months of a child's life. During this period, it grows by about three centimeters every month. Then, in the period of 3-6 months, the child "stretches" an average of 2.5 cm per month. From the sixth to the ninth months, the baby grows by 1.5-2 cm every month, and in the period of 10-12 months - by one centimeter per month.

Thus, the growth of a little man per year increases by an average of 25 cm.

Weight

The average weight (weight) of a full-term newborn baby is 2.6-4.5 kg. In recent years, there has been the birth of an increasing number of "heroes". Nowadays, the birth of a child weighing 4.5-5 kg ​​is not uncommon.

With repeated births, a woman usually gives birth to a baby that is larger than during the first.

In the first day after birth, the baby has a physiological decrease in body weight. This is due to water loss, breathing, sweating and fasting. At the same time, the greatest weight loss in a child most often occurs on the second or fourth, less often on the fifth day after birth. Normal weight loss is about 5-10% of birth weight. In first-borns and large children, weight loss is more pronounced. Boys also lose more weight. By the week of life, weight is restored in approximately 50% of children, by the tenth day - in 75%, by two weeks - in almost all healthy newborns.

More significant weight loss in premature babies (9-14%), and their weight decreases over a longer period of time. Weight recovery in such babies usually occurs 20-22 days after birth.

Growth dynamics

The height and weight of newborns increases depending on many reasons. But some general trends can be identified. So, during the first month of life, the weight of the baby increases by an average of 20 g every day. In the second month, this increase is 30 g. Thus, the weight of a four-month-old baby doubles compared to birth weight, and by 12 months of age it triples.

Pediatricians use a special simple formula to calculate the required body weight. So, in the first six months of a baby's life, his weight is determined by the formula:

Body weight = body weight at birth (g) + 800 × N. In this case, N means the number of months of life.

At the age of a child of 7-12 months, the following formula for calculating the norm of weight is used:

Body weight = body weight at birth + 800 × 6 + 400 × (N - 6).

Babies who are large at birth usually weigh more than their peers during the first year. Newborns whose birth weight did not exceed 3.3 kg should gain more than their peers in the first month, catching up with them at the age of two months.

Mothers should control the height and weight of their children. Of course, the above calculations are not entirely convenient. Therefore, it is better to use ready-made tables of height and weight of newborns.

Tables of growth and weight of newborns

In 2006, WHO established new international standards for height and weight in newborns. These standards define the normal development of a child at an early age and are used to assess the condition of children in all places, regardless of the type of feeding, socio-economic status, ethnicity.

Here is a table of growth of children from birth to a year of life.

Age, months	Height (length) indicators, cm
	boys		boys		boys

In the above table, the average height and weight are those that correspond to the norm. Growth rates that are listed as low and high require a doctor's consultation to ensure a timely examination.

Consider the child's weight table according to WHO standards.
