Monthly infant weight gain. Weight gain in newborns by month

Every mom worries about how her baby is developing, especially if the child is the first in the family. Many are interested in the question: “What should be the indicators of height and weight in children under one year old, their increase by months?”. It should be noted right away that such values \u200b\u200bdepend on several factors:

the nature of the baby's nutrition;
the amount of food eaten;
whether there is a history of congenital anomalies - heart muscle defects, problems with the digestive system, etc.;
whether there is a hereditary intolerance to amino acids or lactose;
what is the activity of the baby.

All these moments play an important role in growth and weight parameters. In addition, every mother should remember that all children are individual, and it is impossible to exactly equal the parameters adopted by WHO. Especially if the baby looks cheerful and active. But, nevertheless, with a significant shortage, it is better to consult a pediatrician.

Normal weight of the child at birth and discharge from the hospital

Each baby is unique in its own way. A healthy baby is usually born with a weight of 2.7 to 3.7 kilograms. However, the final indicator depends on several external and internal factors:

The state of health and general development of the baby.
Of no small importance is hereditary predisposition. If the parents are tall and have an impressive weight, then their children will be large. For thin women, the situation is reflected exactly the opposite.
Due to certain physical characteristics, boys are always larger than girls. The situation is observed both at birth and in the process of general development.
Features of the diet of a woman during the period of gestation. The fetus gains kilograms in the event that the woman did not limit herself to high-calorie foods.
The child reflects not only the physical, but also the psychological state of the woman. If the pregnancy for her proceeded under stress, then the situation can negatively affect the development of the baby. Against this background, the newborn lacks several hundred grams to normal weight and looks thin.
Bad habits during pregnancy are very dangerous for a woman and her fetus. If mom abused smoking, alcohol or drugs, then she may have a child who is far behind in weight.

Body weight control of the baby should be carried out regularly

Additionally, it should be noted that after childbirth, children lose weight by a few grams. Such a sharp decrease in weight occurs against the background of the following factors:

The child begins to breathe on his own, so the fluid accumulated in the womb is removed from his body. The evaporation process takes place through the skin.
It is not possible to set the power mode immediately. During the first days of life, the baby eats in small portions, and the mother's milk is just beginning to be actively produced.
The kid gets into an aggressive environment to which he has not yet adapted. He needs a period to adapt and normalize the functioning of all internal organs. Therefore, a sharp weight loss can be attributed to a stressful situation. After a certain period, this will pass, and the baby will begin to rapidly gain weight.

Normal weight loss between delivery and discharge is within 10%. Subsequent weight gain is calculated based on the last digit.

How to calculate the optimal parameter for your baby?

It should be noted right away that the norm in terms of height and weight was calculated experimentally. Therefore, slight deviations are allowed. In addition, it is worth remembering about genetics. So, for example, if both parents are tall, then it is logical to assume that the baby will be somewhat ahead of their peers in growth. Conversely, in short and fragile people, the increase in the growth of the baby will be lower than generally accepted values.

It is believed that at birth a child should have a weight in the range of 2650-4500 kg, and in the first 7 days of life, he can lose 10% of the initial weight. With normal development, it is considered that a newborn should gain 800 grams every month. But this happens until the baby is six months old, and then the increase goes to 400 grams.

To calculate the optimal weight of the baby, you can use the following formula:
1. Up to 7 months: kg + 800 x N, where

kg - weight at birth;
N is the number of months lived.

2. After 7 months and up to a year: kg + 800 x 6 + 400 x (N-6), where

kg - weight at birth;
800x6 - the mass that the baby acquired in the first six months of life;
N is the number of months after the last 6 months.

But here it’s worth saying right away that doctors always look not only at the growth of children, but also at their mass, and compare their ratio. Only then can we judge whether the child develops harmoniously.

A newborn baby is born with a weight of 2.6 - 4.5 kg. From this weight, the increase and the due mass are calculated.

What increase should you aim for?

If you go online to any children's site, then there will always be a table of weight and height with "exact" values, on which many mothers begin to rely. But as mentioned above, each child is individual, so it’s not the indicators that should be calculated, but the increase values themselves.

And so that young parents have less worries about this, it is worth familiarizing yourself with the approximate figures in the increase in height and weight of newborns.

1. In the first month of life, the baby should add 0.6 kg in weight, 3 cm in height and head circumference should increase by 1-1.5 cm. Nutrition in this period should be every 3 hours and it is best if it is maternal milk. Otherwise, the volume of the mixture should be 80-120 ml.

2. By the end of the second month, another 600 grams should be added to the weight, 3 cm to the height, and 1.5 cm to the head circumference. Pauses between feeding should be 3.5 hours. At this time, many pediatricians recommend weaning the baby from night feeding. Therefore, if you listen to the recommendations, then weight gain may be less.

3. The third month is characterized by an increase of 0.8 kg in weight, 2.5 cm in height and 1.5 cm in head circumference. Feeding continues every 3.5 hours, but for "artificial" babies, a deviation from the schedule of 20-30 minutes is acceptable. The volume of food eaten increases to a mark of 130-150 ml. It is worth noting that this is a period of colic, which means that the baby's appetite may be somewhat disturbed.

4.4th month - + 750 gr, height - + 2.5 cm. The average feeding period is 3.5 hours for 150 ml. It is immediately worth noting that in the future the child will gain weight by 50 grams less than in the previous month.

5. At 5 months, the child adds 0.7 kg in weight, 2 cm in height. On average, now the baby should have a height and weight twice as large as those that he had at birth. At this stage, the child can already introduce complementary foods, but gradually, following his reaction. For example, they start with a teaspoon (without a slide) of applesauce, which after a week can be increased to 50 grams. By the 6th month, they can already replace one full meal.

6. In six months, the baby should add 650 grams, and grow by another 2 cm. The child is harmoniously developed if the width of his shoulders is 1/4 in relation to the length of the whole body. In this case, the parameters of the head circumference should be less than the value of the chest circumference. At this age, the feeding interval can be changed to every 4 hours.

7. At the seventh month, the normal weight gain is 600 grams, and in height - 2 cm. The baby is fed every 4 hours. Usually at this stage, you can replace one breast milk meal with one serving of light porridge. It is best if complementary foods are in the morning.

8.8th month - 550 g will be added to the weight, and 2 cm to the height. Here you can already diversify the diet by adding dairy products to the diet - cottage cheese, baby yogurt, milk.

9. In the ninth month, the child will add half a kilogram and grow by 1.5 cm. Vegetable puree, dietary meat (chicken breast or rabbit), and half a chicken yolk (or a whole quail yolk) are already here. But any complementary foods are always introduced, starting with a teaspoon. Gradually, its amount should increase in volumes up to 150-180 ml / g. Otherwise, the child may get an allergy.

10. By the end of the 10th month, the average increase in children of this age is 450 grams. Height increases by another 1.5 cm. The baby can drink about 70-80 ml of fruit juice per day. Banana, peach, plums and black berries are added to the diet. You can add 5 grams of vegetable oil to the porridge.

11. At 11 months +400 gr in weight, +1.5 cm in height. Sea fish is introduced into the menu, making meatballs out of it or just mashed potatoes.

12.Year. By this time, the baby should weigh: kg (birth weight) x 3. And the approximate height should be 25 cm more than the original one. In addition to meat and fish dishes, vegetables should already be present in the diet of the crumbs. During this period, you can gradually move away from mashed potatoes, making food finely chopped. This will help the baby develop motor skills of the hands and learn to eat on their own.

But it is immediately worth noting that all the values \u200b\u200bgiven are approximate. Therefore, if the height of the newborn or its weight do not match, you should not immediately panic. You just need to consult a pediatrician. In addition, teething should not be overlooked, as it is always accompanied by a decrease in appetite. And this means that in a certain month, the schedule for gaining mass and growth may go astray. But then the baby will “catch up” with his performance.

It is very important that parents monitor not only the growth of the child by months, but also his psychomotor development. In each period, the baby must have certain skills.

Important parameters of the physical development of the baby are not only weight, but also height, head circumference of the baby

What problems can parents face?

There are a number of things that can happen to a baby. As a result, there will be deviations in weight gain and growth parameters:

If the baby was born large (more than 4500 grams), then his performance will exceed the norm. It can also be observed in a child whose parents are prone to overweight or have diabetes.
Children with low weight may not gain weight due to intrauterine infection, placental insufficiency, or the presence of pathologies of internal organs.
Also important is the quality and volume of breast milk. If there is a lot of it and it is fat, then the baby will be larger than his peers. To understand that the crumbs have enough of everything, you need to pay attention to his behavior. Having sated, the baby will calmly fall asleep and not wake up for 3 hours. Otherwise, the child should be fed.

But before you measure the growth of a newborn, it must first be undressed. After that, the baby should be laid on the back on a special board with measurements and the legs should be completely straightened. In this case, the head should rest against the upper bar. Such a "tool" can be purchased at a children's store or just wait for a scheduled examination by a pediatrician. Up to a year, growth in children is measured every month.

In no case should you despair if the baby does not meet the "standard" parameters. You just need to pay attention to your relatives, maybe the kid just went to his grandparents in height and equipment, so he is taller or lower and thinner or fuller.

Floor. Boys tend to outnumber more fragile girls at birth.

Heredity. It is obvious that tall, stately parents will have larger children than a petite young mother and father of average build.

Nutritionmothers during pregnancy. Often, with a woman's high-calorie diet, the fetus gains weight even before birth.

The physical and psychological state of the mother during pregnancy. Stress and illness, of course, affect the health and, as a result, the weight of the baby.

Mom's bad habits- smoking, alcohol. In this context, the weight of the child also depends entirely on his health.

Infant weight at discharge

You need to be prepared for the fact that in the first days of life the baby will lose a little weight - by 6-10% of birth weight. This is easily explained by the fact that the baby is experiencing stress. He needs time to adjust to the new conditions of life. Mom should be lactating. At first, the newborn will get by with small portions of colostrum, since his stomach is very small. In the future, weight gain is calculated from the figure at discharge.

Weight gain in infants is a consequence of various reasons.

Appetite.

well-being. When the baby is unwell, he eats worse.

Type of feeding. Formula-fed babies gain weight faster than babies.

Quality and quantity of breast milk(with natural feeding).

Child mobility. Active kids are more fit than lazy ones.

Modefood. When feeding "on demand", weight is gained faster than with the "hourly" mode.

Age. In the first months, babies grow faster, gradually weight gain slows down.

Norms of weight gain for newborns

So how much should a newborn gain weight? A normal increase in the first month of life is 90-150 grams per week. For 2, 3 and 4 months, the baby should "grow" by 140-200 grams per week. From 5 months to six months, the increase will decrease to 100-160 grams per week. Then the child will add a little in weight and by his first birthday he should weigh about 3 times more than at discharge.

Monthly newborn weight chart

This table is, of course, rather arbitrary. It is important to remember that children are individual in their development - one may grow faster, the other slower. If the baby is healthy and cheerful, the parents should not have any reason to worry about “non-standard gains” in weight.

The height and weight table, which shows the dynamics of changes in children under the age of 1 year, allows you to evaluate changes in their development that have occurred over this period of time. The numbers indicated in this table reflect several types of indicators (from low to too high) and show variants of the norm and deviations from it in both directions.

Physical and mental development of the child by months

The table of height and weight of children up to a year allows you to track the active phases of the growth of the baby. The first year is a special time when a child develops rapidly month after month and acquires new skills and abilities. Each baby is unique and its development proceeds at a certain pace; these changes cannot be tied to a specific plan and period of time.

However, each parent can track the development of their child in order to be able to help their child in time in mastering those skills that are not yet given to him, but are already required by age.

The development of each child is a multifaceted and complex process, depending on many factors. You should not blindly follow the generally accepted criteria, but you need to focus on them so as not to miss the time for the development of the baby.

Norms of weight gain and dew of a child up to a year. Table:

Dr. Komarovsky will tell you what weight and height a child should have up to a year:

The birth of a child is a wonderful event in the life of every parent, but there are things that require special attention, for example, rate of weight gain in newborns by months, table provides parents with data on how many kilograms a child should show the normative parameters of weight gain monthly from the moment of birth. Each child is examined by a pediatrician; during the first visit, weighing and measuring growth are carried out. In the process of hospital care in the first days of life, doctors check the general condition of the baby.

Norms by weight

All children are individual, and it is not surprising that they are born with different parameters. The standard value of the first parameter is from 2.7 to 3.7 kg.

The initial weight depends on several factors:

Features of the development of the child in the womb. How much should a newborn gain in the first month in weight, has a dependence on the conditions provided by parents for full growth.
A mother who smokes and abuses alcohol risks giving birth to unhealthy children who do not gain weight well after birth.
Heredity factors show that large mothers give birth to large children, and miniature women give birth to small babies.
Sex characteristics of the child. In fact, boys are born larger than girls.
Principles and proper nutrition of the mother. For example, if during pregnancy a woman's diet is dominated by high-calorie foods, then children will be born larger.
If a mother suffers from chronic or acute diseases or is often under stress, this, one way or another, is reflected in the weight of the baby born.

weight gain in breastfed newborns by month, and what it depends on, in the article.

Weight parameters at discharge

Initially, after birth, there may be weight loss caused by aspects.

Leaving the body of fluid due to the start of the respiratory system.
Supply system. In the first days of life, the baby consumes colostrum in small quantities, so it is necessary to wait until he has an established nutrition system, and full-fledged milk does not arrive for his mother.
Adaptation to typical living conditions. A child at birth changes the environment and, in this regard, faces certain difficulties. The difference in weight can be up to 10%.

Consider what should be the normative values and their dynamics.

Norms of indicators

The baby gradually learns to eat, his digestive system begins to improve, heat and air metabolism normalizes, as a result of which he is gaining weight at a rapid pace. That, how much weight should a newborn baby gain at 1 month and more, depends on a number of factors. For example, key points include such as the health of the child, his appetite, type of feeding, amount of food consumed, degree of mobility, age.

Summary table of weight gain

Despite the individuality of each baby, there are generalized parameters that are normative for each of them. So, how much should a newborn gain weight by month, table.

Age, months	1	2	3	4	5	6	7	8	9	10	11	12
Gain, g	700	700	700	670	670	670	550	550	550	350	350	350
Average height gain cm	3	3	3	2,5	2,5	2,5	1,5	1,5	1,5	1	1	1

So, boys usually gain weight more intensively than girls, but by the age of 1-1.5 years, all indicators become the same.

Let's take a look at what he recommends. how much should a newborn gain weight by months Komarovsky

It is in the first months of life in the world that the child is most actively gaining weight. - around 700

First three months. It turns out that at discharge (in the first 4-5 days from the moment of birth), the baby loses weight, and then begins to rapidly gain weight. As for growth, at this stage of life, its rate is also the fastest, on average - 3 cm per month. By three months, the growth rate of the baby reaches 55 cm.
For the second three months, the rate of weight gain decreases slightly, in a month the weight can be gained up to 670 kg, sometimes up to 700 kg. By six months of life, a baby can weigh an average of 6.5-7.5 kg, and its height is gaining 2.5 cm per month, and by 6 months it is 65 cm. This is a normal value for absolutely every baby.
The third "trimester" of the baby's life is accompanied by an increase in weight by 550 g per month and an upward change in the growth rate - 1.5 cm.

The baby begins to show a different behavior, interest in everything, and also wants to eat as much as possible and leads a more active and mobile lifestyle.

The last three months of the baby's first year of life are the least active in terms of growth and weight, however, it can be noted with confidence that the baby is becoming stronger, his digestive system has adapted to environmental conditions by 100%, he feels good. At 1 year of life, a healthy child gains weight up to 10 kg, and the growth rate is 74 cm.

So, we have considered the table, how much weight should a newborn gain in 1 month. It turns out that at first the child grows more rapidly, and approaching the milestone of 1 year, the growth rate slows down. Normal weight values depend on a number of factors and are individual for each baby.

Deviations from the norm: is there a reason for excitement?

Often, the development of the child has certain deviations from the above norms and averages. It may be that the baby is quickly gaining weight, or, the opposite phenomenon - when there is a lack of mass and growth. Both cases are not very good, because with insufficiently fast and active recruitment, it is necessary to review the baby's diet and diet, and with a large weight gain, the baby becomes obese, which prevents him from moving and developing normally. So, how much weight does a newborn gain in the first month can be seen in the table. If there are deviations, they can occur for a number of reasons.

The individuality of physiology, which caused the excessive or, conversely, insufficient growth of the baby.
The initial indicators of height and weight affect the dynamics of their set. For example, a baby born with a weight of 3.6 kg is easier to gain weight up to 5 kg than a baby who was born with a weight of 2.5 kg.
The gender of the child is one of the key factors. It is often observed that boys gain weight faster than girls.
Type and features of nutrition. A breastfed baby gains weight more slowly than a formula-fed baby.

There are other signs that influence the fact that how much weight should a newborn gain in the first month and for the next time. Providing the baby with normal developmental conditions contributes to the fact that all his indicators are normal, this ensures good health for the child and peace of mind for parents. We wish you success in raising crumbs and good mood every day. Raising a child is happiness.

Surprisingly, we forget a lot in life, but we remember the height and weight of a born child all our lives. Probably, it is inherent in the nature of a woman-mother to know and remember these numbers, because by them, by their changes, we judge the state of health of the baby.

The weight of a newborn baby is an important indicator of its development. Therefore, the first measurement and weighing is carried out immediately or a couple of hours after birth. These indicators are carefully recorded in the journals of maternity hospitals and are recorded in a tag on the baby's handle.

There is a practice of daily weighing of infants while they are in the hospital. The medical staff carefully monitors the dynamics of the increase or decrease in size, takes measures to regulate the data. Then, having been discharged from the hospital, the parents go to the clinic for control weighing and monitor the addition of grams and centimeters by months.

Dimensions at birth

According to the standards set by the World Health Organization, the average birth weight of a boy is 3400-3500 g. And girls are born smaller - 3200-3400 g. These are average figures, in fact, the weight of children at birth is much higher or lower than WHO data.

The birth of a baby from two and a half to four and a half kilograms is considered normal. Children born with a weight below or above this data are considered premature or too large. If the parents of underweight children are not very short, and the parents of overweight children are not giants, then the children are at risk. They may have psychomotor and other disorders, neonatologist and pediatrician constantly monitor them.

The norm of weight at birth is 2500-4500 g. If the baby weighs less or more than these values, he is at risk for health

In fact, the weight of a newborn depends on many factors.

If parents are people of average build and height, then their children are born with a weight of about 3 kg, that is, within the average weight, according to WHO.
The second and third children of the same mother have a higher weight than first-born babies. Parents over 35 years old have larger children than younger ones (although there are exceptions).
A child whose mother during pregnancy ate inadequately, did not adhere to the regimen, had bad habits, will be born thin.
A pregnant woman eating fatty, sugary, high-calorie foods will give birth to a larger baby.

Weight gain up to a year

In the first days of life, the baby physiologically loses up to 250 grams. This is normal, since the baby is still not eating enough, and there are quite a lot of liquids coming out. After a few days, weight gain begins.

A special weight and height calculator will help you calculate the correct weight of the child by months. You can do this using formulas yourself. Calculation up to six months.

For example, such an option. The baby was born with a body weight of 3100 g, the weight at two months should be as follows: 3100 + 800 x 2 (age in months) = 4700 g.

Another variant. It is accepted that in six months the child weighs 8200 g, in 2 months the baby will grow to such sizes: 8200 - 800 x 4 (does not reach up to six months) = 5000 g.

From six months to a year, the weight of a child is calculated using a different formula.

First option: 3100 + 800 x 6 + 400 x 7 (number of months) = 10700
Second option: 8200 + 400 x 7 (number of months) = 11000

It can be seen from the examples that the calculations are approximate, each formula gives its own result. At the same time, the formulas show what weight to focus on for parents. Nature develops a child according to its own laws, and its mass may well not correspond to the calculated data.

Medical scientists have developed a special calculator with which you can easily, quickly and accurately calculate the weight and height of the baby for each month and week. For convenience, a quick calculator is placed on our website. You can use it to calculate your baby's body weight.

Deviations from the norm

Characteristic marks in the development of the baby are based on indicators of weight and height. When asked how much a child should weigh at a certain age, your pediatrician or centile tables, developed on the basis of WHO medical research, will answer you. The centile tables present indicators of the norm of weight and deviations in the direction of increase or decrease.

To estimate your child's weight or height, measure and weigh their height. Find the age of the baby in the tables, compare with the figure that you intended. In the colored "frame" of the table - indicators of the norm. Everything to the left and to the right are deviations.

For example, your child is 7 months old. Height - 68 cm, and body weight - 8 kg. These figures fall into the lilac "frame" of the table, and this is the norm.

Infants up to six months during each month add 600-800 g and grow by 2-3 cm. After six months to a year, the increase decreases slightly and ranges from 600 to 350 g and from 2 to 1.5 cm in height. These are average standards that correspond to the development of a healthy child. Changes in the baby, which differ in the direction of increase or decrease, indicate nutritional errors and health problems. In order to solve problems in time, it is necessary to consult a pediatrician, neurologist or endocrinologist. Therefore, it is so important to monitor the anthropometry of the child.

Table of monthly changes in weight and height of the child

Based on anthropometric data, the weight and height calculator will calculate the dimensions prescribed at a given age, calculate the body mass index, make an assessment of deviations and display indicators of the correspondence between the height and weight of the newborn. Based on these data, the pediatrician will identify possible inconsistencies and give recommendations on the nutrition, development or treatment of the baby.

The body mass index of the baby is an important indicator of development. With the help of ITM, it is possible to accurately assess whether the height, weight and age of the baby correspond to the norms for months. The formula for calculating BMI is simple, every parent can handle it:

I (index) \u003d M (mass in kg): H2 (height in m2)

The generated conclusions show how the baby grows and adds, and also gives an estimate of the weight by months. If you get an average, then the crumbs have normal development, they have enough nutrition. If the weight is less or more than average, but corresponds to your family constitution, this is also normal. And underweight or even severe underweight, as well as a very large weight, speaks of a pathology, a specialist consultation is necessary.

Central table of changes in weight and height of girls

It should be noted once again that all indicators are averaged, calculated for the average child. If you get deviations from the norm, do not rush to panic, first show the baby and the calculations to your pediatrician. The doctor will evaluate the dynamics of indicators, study the condition of the crumbs, draw the right conclusions, the necessary appointments.

Reasons for underweight

Using tables, formulas, or using a calculator, you find that your baby is underweight or overweight. This is a signal to parents about nutritional problems. Until the doctor has diagnosed malnutrition, watch the baby. If the baby is inactive, drowsy, lethargic, then it is quite possible that he lacks mother's milk, which means activity, strength for growth, and harmonious development.

Pediatricians distinguish between two causes of underweight: internal and external. In a normally born child, without anomalies and injuries, internal causes are not considered. And external causes are associated with a lack of nutrition. Loss of weight due to a lack of nutrients will be reflected in the body of the newborn by the development of anemia, immune problems and other disorders.

The main cause of underweight is most often nutritional deficiencies. That's what you should be focusing on

Analyze the reasons why the crumbs may be underweight for his age, as well as his loss. Or, conversely, too much weight. Perhaps you are not lactating enough, the baby does not have enough milk, and he is hungry. Perhaps the baby is sucking out only the front, sparse milk. Or maybe you live in constant stress. This feeling is transferred to the child, and he fights stress with you, wasting all his energy on the struggle.

Is there enough food for the child?

To understand why a small child is not gaining as much as he needs, whether he has enough food, check his diapers. A well-fed baby soils diapers at least three times a day, and urinates at least 8-12 times.

You can observe the baby's nutrition for a maximum of a month. Compare the graph of the dynamics of weight and height, which normally change proportionally. Check if the baby has learned activities and skills appropriate for his age.

If, apart from weight indicators, nothing in the baby worries you, if the baby is alert and active, sleeps calmly, sucks well and poops on time, then underweight may not play a decisive role - you have an absolutely normal child.

If you notice a developmental delay, this is important. For example, at 3 months, the baby does not know how to hold his head for more than 4 minutes, open his mouth when approaching the nipple. Draw conclusions, consult a doctor to take action.

Remember, boys usually gain weight faster than girls, so you should not compare the first-born son with the second child - the daughter, and run to the pediatrician in a panic that the baby weighs a couple of kilos less at the same age.

Deviation from the norm (mainly in the direction of overweight) may be in artificial children. Depending on what mixture they eat. As a rule, premium formulas are more balanced than budget lines; babies do not get fat from them.
