Calculation of the amount of formula for a child calculator. How much formula does a newborn eat?

One of the important elements that promotes growth and development is proper nutrition of the child, in which the quantity and quality of food is balanced according to the needs of the baby. Specialists in the field of pediatrics and nutrition have developed nutritional standards for children in the first year of life, violation of which can significantly affect the baby’s health and his physical and mental abilities.

An addition may be indicated in the following cases. Difficult social conditions, parental neglect; anorexia or other eating disorders, loss of appetite, use of complex diets; chronic diseases; weight loss; strict vegetarian diet. The administration of vitamin preparations should always be discussed with your physician.

Can baby formula be prepared once a day at home and stored in the refrigerator?

Handbook of Pediatric Nutrition. A.: Multivitamin and multimineral nutritional supplements: definitions, characteristics, bioavailability and drug interactions. Contrary to popular belief, baby formulas are not sterile. Sometimes, but sometimes during production or preparation for use, the mixture is contaminated with pathogenic microorganisms. Some bacterial infections have caused serious illness and even death in bottle-fed babies. With this in mind, the Nutrition Committee of the European Society of Gastroenterology, Hepatology and Infant Nutrition has formulated recommendations for mixing.

Thus, insufficient food consumption by a child in the first year of life can contribute to the development of dystrophy, rickets, and prolapse of the kidneys, which are supported by adipose tissue. Children's nutrition, which does not correspond to the age category in quality and composition, can lead to delayed development of the child, absence of teeth or poor quality, diathesis, allergic reactions, nervous system disorders, mental retardation, anemia.

How long should you breastfeed exclusively?

It is recommended to take it at home.
Prepare fresh formula before each feeding; remove residues after each feeding and do not use them during subsequent feedings; adhere to the principle that infant formula should not be stored in thermoses or bottle containers; An alternative solution is to store heated water in a thermos and add the powder directly to it before feeding. This recommendation applies to the average population and other proceedings may be warranted in selected cases. Healthy nutrition for children is especially important in the first year of life

, when the basic functions of the body are laid down and lack of weight, or the lack of any vitamins or vital microelements, can affect the child’s overall health.

Calculation of nutrition for children in the first year of life can be done based on the need for the amount of food, knowing its calorie content and the baby’s weight. In addition, breastfed children in the first six months can be fed exclusively on mother's milk.

, which satisfies all their needs for nutrients and promotes the normal development of all organs, and also supplies the body with immune cells that protect the baby from the effects of infection.

What foods other than milk should be introduced into a child's diet first and what is the reason for feeding them?

Conclusions and recommendations.
The optimal age and timing of supplementary feedings is the subject of much debate. Additional foods should not be introduced until the end of the week, but all children should be introduced before the end of the week. There is no scientific evidence that avoiding or delaying the introduction of potentially sensitive foods such as fish and eggs reduces the incidence of allergies in infants at risk for allergies and those not at risk. Breastfeeding is carried out at the request of the child, who himself determines how often and in what quantity he needs food. As a rule, by the end of the first month of life, the rhythm of breast milk production, as well as its composition, are synchronized with the baby’s needs and no problems arise. The following factors indicate that a baby does not have enough breast milk:

They should provide sufficient amounts of easily absorbed iron. Cow's milk is a poor source of iron. This should not be the main drink until one month of age, although small amounts of milk may be added to additional foods. Do not use vegetarian diets for infants or young children. However, if they are on a vegetarian diet, they should consume enough milk and dairy products.

According to Polish recommendations, the introduction of additional nutrition should begin after a month of life and before a month of life. It is recommended that new foods be introduced separately, one at a time and in small portions, observing the child's reaction. The order in which individual products are introduced is likely not significant and may be subject to change.

• The number of wet diapers per day is less than the number of feedings.
• The baby hangs on the chest for a long time and falls asleep more likely from fatigue than from satiety.
• He often wakes up with a hungry cry and only becomes silent after he has been given the breast.
• Weight gain does not correspond to monthly growth rates.

If there is at least one of the factors listed, you need to contact a pediatrician who will help you do a control weighing before and after feeding, and also send breast milk for research in terms of its fat content and density. If it turns out that there really is not enough milk, options are possible: supplementary feeding with formula after the main feeding or complete replacement of one or two feedings with food for children.

When should you add a baby apple to your child’s diet?

References: Dobrzanska A. Czerwionka-Saflarska M. Kunacevich H. et al.: Recommendations for feeding healthy children in the first year of life. A group of experts appointed by the National Consultant. According to European recommendations, additional products should be introduced no earlier than the end of the week and no later than the week of life.

When can children start yogurt? Is it safe for children with milk allergies?

Polish recommendations are very similar. New foods should be introduced separately, in turn, by observing the child's reaction and starting with small portions. The order in which certain products are added is likely to be minor and subject to change. In many European countries, yogurt is gradually introduced into children's diets between one month and one month of age. In Poland, it is recommended to take yogurt from the month of life, initially in small portions 1-2 times a week.

The nutrition of children under one year old who are initially on formula must be under the control of their parents and meet age requirements; it is very important to follow the feeding schedule, give the baby the amount required for his age and take into account the composition of the formula.

It is best to give yoghurts containing only natural ingredients without preservatives. Yogurt should not be given to children who are allergic to cow's milk protein. Small amounts of milk may be added to additional products. Bibliography: Dobrzanska A. Czerwinka-Saflarska M.

When can children get fruit juices?

According to Polish recommendations, additional nutrition can be given after a month of life and up to a month of life.

Should you limit your baby's juices if they like them and want to drink them?

Only the American Academy of Pediatrics has developed recommendations for the rational consumption of fruit juices. According to them: fruit juices have no significant nutritional value for infants under one month of age; Fruit juices are no more valuable than whole fruits when breastfeeding after one month of life; 100% juice or juice concentrate that is part of a balanced, age-appropriate diet can have significant nutritional value; The nutritional value of fruit drinks is not the same as fruit juices; Juices should not be used to treat diarrhea during diarrhea; Excessive supply of fruit juices can cause eating disorders; Excessive juice consumption may be accompanied by symptoms such as diarrhea, flatulence, abdominal pain, dental damage; Unpasteurized juices may contain pathogens; the introduction of various juices at the appropriate age of the child probably does not cause any clinical symptoms; Lime-fortified juices provide a bioavailable form of this mineral but do not contain any of the other nutrients found in breast milk, modified milk, or cow's milk.

How much formula should a newborn eat?

Of course, ideally, you should breastfeed your baby exclusively; when breastfeeding, you don’t need to do any nutritional calculations, you just need to feed the baby on demand.

But if for some reason it didn’t work out with breastfeeding, it is necessary to choose the right formula for the child and accurately calculate the amount of nutrition he needs from the first day of life.

The first days of a child’s life are the most important in terms of adaptation to a new diet and lifestyle, and it is important to make accurate calculations of the amount of formula that a newborn should receive per day and per feeding.

Up to 10 days of a child’s life, calculations are made based on the weight of the newborn at birth.

How to determine if a child is full?

During the entire time the child is feeding, he eats different amounts of formula. And the baby’s appetite may not be constant. And therefore, when artificial nutrition begins, it is sometimes recommended to use free feeding. As a result, the child eats when he wants, but the mother must monitor the amount of food eaten at one time. Pour 15-20 ml more mixture into the bottle and give at the set time, deviating from the schedule by at least 30 minutes. And when the child has eaten enough, do not force him to drink the rest. To understand whether a child is full or not, you need to determine how much formula the child needs to eat per day and how much is needed for one feeding. But when your baby demands food ahead of schedule, you should recalculate the amount of formula you give your baby.

All mothers worry about whether the child is getting enough to eat, regardless of whether they are breastfeeding or have an artificial child. If it is easier with infants, they are latched to the breast on demand and themselves regulate the amount of nutrition that they need in order to eat, then artificial babies need to carry out nutrition calculations so that the child does not remain hungry, and at the same time, he is not overfed.

Nutrition calculations for artificial babies are necessary because the volume of the stomach at birth in children is no more than 10 ml and gradually increases as they grow. It is important that the child receives enough nutrition and does not overstretch the stomach or overload with food.

There are several ways to calculate nutrition:

For children weighing up to 3.2 kg at birth, the volume of formula per day is equal to the child’s age in days multiplied by 70.

A child weighing 2.8 kg at the age of seven days needs 420 ml of mixture per day according to this formula. This daily volume is divided by the number of feedings, obtaining the volume of one feeding. At this age, children need to be fed at least eight times a day.

For children weighing more than 3.2 kg, the formula looks like this: number of days of life of the child * 80. This will be the volume of formula per day, and the amount of formula per feeding is obtained by dividing this volume into 8 feedings.

Today, on modern packaging of formulas, manufacturers provide a calculation to help mothers calculate how much formula a newborn should receive at one time and per day.

Amount of nutrition after 10 days of life

Just as in the first 10 days of life, in the future, the amount of nutrition for a child on artificial nutrition is calculated based on the child’s body weight. The calculation is carried out according to this principle:

• up to one and a half months, a child needs 1/5 of his weight per day;
• up to 4 months 1/6 of body weight per day;
• from 4 to 6 months up to 1/7 body weight, but not more than 1000 ml;

After this age, no more than 1/8 of body weight.

For example, a child aged 1 month with a body weight of 4200 g needs per day:

4200: 5 = 840 ml of mixture.

The number of feedings per day also depends on age, and is:

• children under 2 months need 8-10 feedings per day, including at night;
• children 2-4 months old need 7-8 feedings per day;
• children 4-6 months old 6 feedings per day;
• after 6 months 5-6 feedings.

Thus, it is not difficult to calculate how much a newborn should eat at one time. From the example above, we divide 840 ml into 8 feedings - 105 ml per feeding.

Attention! You should not look at the diagrams indicated on jars of baby food and the volumes of one feeding that are offered there.

They are given for the average child, and the standard volume of formula for your toddler may be either excessive or insufficient.

Nutrition calculations are carried out specifically for your baby by a pediatrician or by yourself. Typically, the data on formulas is artificially high, which uses up food faster and forces you to buy more formula. At the same time, children suffer from overfeeding, which can later lead to metabolic disorders and obesity.

Baby's nutrition after one year

The diet of a one-year-old child differs markedly from the diet of an infant, for example, the amount of food consumed per day can be 1250 ml. in this case, meals are reduced to 4. It is recommended to increase the interval between the last meal and breakfast.

So, after one year of age, children's meals begin with breakfast at about 8 a.m.; dinner should not be later than 9 p.m. - 00 p.m.

A child's annual diet consists of 25% of the daily value for breakfast, 35% for lunch, 15% afternoon snack and 25% food for dinner.

Recipes for feeding a child after one year should include dairy products, poultry, beef, vegetables, fruits, cereals, fish, eggs, and vegetable fats. You should give your child as little sweets, flour products, and animal fats as possible. Categorically, the diet of a child over one year old does not include carbonated drinks, chips, sausages and other fast food dishes. Such food contains many dyes and flavors, which can have a strong effect on the pancreas or liver at one time, cause gastritis, ulcers, or cause severe poisoning.

The nutrition of a 1.5-year-old child usually does not include breast milk or formula, which, of course, can be consumed by a child at this age if the mother wants it, but they do not carry any particular value. Food should be more solid and not homogeneous. Little by little, fried foods can be introduced into the menu as when feeding a 2-year-old child, for example cheesecakes, pancakes with cottage cheese, cutlets. At the same time, you should not allow the overly fried crust to affect the baby’s pancreas. At this age, children are very capricious and selective in their food, so when preparing it, the design of the dish, as well as the dishes and serving, play an important role. From this age you can also begin to teach your child proper table manners.

Calculation of the amount of nutrition for children of the first year of life

Calculation of food volume for children from birth to 10 days

— the calculation takes into account the child’s body weight at birth: if the body weight is 3200 g or less, then the coefficient is 70 (ml), if the body weight at birth is more than 3200 g, the coefficient is 80 (ml).

V= coefficient (70-80) × n (where n is the number of days of the child’s life).

Example - Calculate the daily and one-time volume of food for a 7-day-old child with a birth weight of 3,800 g.

Answer:

Daily volume: 80 (ml)×7 =560 ml.

To determine the volume of a single feeding, it is necessary: ​​divide the daily volume by the number of feedings. For example, 560 ml: 7 (times) = 80 ml.

Zaitseva formula

daily amount of milk (ml.) = 2% of body weight at birth × n (where n is the number of days of life of the child), the method is mainly used in calculating the daily amount of food for children who have a birth weight of more than 4 kg.

Example: Calculate the daily amount of food for an 8-day-old child with a birth weight of 4,200 g.

Answer:

2% by weight = (4,200 (g)×2):100% = 84 g

food volume per day == 84 (g) × 8 = 672 (ml) = 670 ml.

Filatov's formula

single volume = 10 * n

Calculation of food volume from 10 days to a year

— the child’s age and body weight at the time of nutrition calculation are taken into account.

The baby should receive milk:

from 10 days to 2 months - 1/5 of the required body weight;

from 2 months to 4 months - 1/6 of the required body weight;

from 4 months to 6 months - 1/7 of the required body weight;

from 6 months to 9 months - 1/8 of the required body weight.

The method is used for up to 9 months. After 9 months - 1 liter, since the volume of food in the first year of life should not exceed 1 liter per day.

Example: Calculate the daily and one-time amount of food for a 3-month-old child born with a body weight of 3,200 g.

Answer:

required mass – 3,200 + 600 +800 + 800=5,400

daily food volume - 5,400: 6 =900 (ml)

number of feedings – 6 times

single volume – 900 ml: 6 =150 ml.

Calorie method

(energy) - are based on the caloric content of the type of milk nutrition that the child is fed, and his physiological caloric needs depending on age.

The method is used only before the introduction of complementary foods and subject to one type of food.

Calorie content of human milk = 700 kcal/l. We know the calorie requirement for natural feeding:

I quarter -120 kcal/kg per day

II quarter—115 kcal/kg per day

Example: A child is 4 months old, weighs 3,000 g at birth, and is breastfed. Calculate the daily and one-time amount of food.

Answer:

Caloric requirement = 115 kcal/kg per day.

Proper mass = 3,000 + 600 + 800 + 800 + 750 = 5,950 (g).

Caloric daily requirement 115 (kcal) × 5,950 (g) = 684.25 kcal/day.

1000 ml of human milk - 750 kcal

X ml of human milk - 684.25 kcal.

Daily volume = 1000 x 684.25: 750 =912.33 ml =900 ml

Number of feedings - 6

Volume per feeding == 900 : 6 =150 ml

Children's needs for basic food ingredients

The energy requirement is slightly less – 110 kcal/kg per day.

After the introduction of complementary foods, for breast-fed children, the ratio between proteins, fats and carbohydrates is 1: 2: 4, which provides balanced nutrition for a child in the first year of life.

Nutritional correction should be carried out in case of deficiency conditions, which are most common at an early age. In case of detection of signs of vitamin or microelement deficiency (clinical manifestations of mono- or polyhypovitaminosis, anemia, rickets, etc.), which are not associated with a violation of their absorption in the child’s gastrointestinal tract or with other reasons on the part of the child, namely with insufficient nutritional admission. It is necessary, first of all, to pay attention to the health and diet of the mother. If necessary, provide her with assistance, and only as a last resort, recommend introducing complementary foods earlier (but not earlier than 3 months), first starting with juices and fruit purees.

If at the age of 3-4 months there is an insufficient increase in body weight and other signs of an insufficient amount of milk, you need to help the mother increase its amount, if necessary, supplement the baby with highly adapted milk formulas, and not start with cereals, vegetable purees and other dishes.

On the other hand, in case of acute diseases, dyspeptic disorders, food allergies, the introduction of complementary foods is somewhat delayed. They do not begin to administer it during the hot season or during planned changes in the child’s life (for example, family relocation).

Correction of the need for vitamins and mineral salts

Vitamin deficiency Occurs in the first days of life due to low vitamin content in human milk or in the case of early hypogalactia. A single parenteral administration of vitamin K to newborns is recommended.

Vitamin D deficiency occurs due to its low content in human milk and lack of sun exposure in the first weeks of life. That is why it is recommended to prescribe 200–400 IU of vitamin D per day for the period until regular exposure to sunlight is ensured. For example, during the cold season, water-soluble vitamin D3 is prescribed prophylactically, 1 drop daily.

With natural feeding, from 2–3 months of life, a deficiency of certain minerals gradually begins to develop. The most fully studied deficiency is in relation to iron and copper - elements necessary to maintain normal erythropoiesis.

Iron deposited in the prenatal period is utilized by 4-5 months of extrauterine life.

The lack of vitamins in human milk, starting from the second half of the year, is compensated for by juices, vegetable and fruit decoctions.

Calculation of nutrition for newborns

Is it necessary to calculate the volume of milk when breastfeeding or formula for a child of the first year of life? How to do this if necessary? What are the consequences of uncontrolled feeding? Today we asked pediatrician Olesya Vladimirovna Butuzova about this and much more.

— Olesya Vladimirovna, please tell us why it is important to calculate the amount of nutrition for a baby in the first year of life.

“Everything is important for a baby in his first year of life. Moreover, nutrition, thanks to which it actively grows and develops. Both quality and quantity matter. If a child does not have enough food, he becomes weak, slows down in mastering skills, and lags behind his peers in weight and height. Excessive nutrition is fraught with extra pounds and obesity - a real scourge of modern children.

— Let's talk about how to calculate the amount of breast milk that a baby needs.

— As I think most modern mothers know, we feed our babies breast milk on demand. And no calculations are needed here. The baby himself calculates - as much as he needs, so much is applied to the breast. We monitor it by weight gain: the first three months, ideally, babies gain 800 g, the next three months - 700-750 g. If the weight gain is significantly lower, we raise the issue of a lack of breast milk and the introduction of supplementary feeding in the form of adapted milk mixture.

The baby himself regulates the frequency and duration of stay at the breast - this is how nature works, no additional calculations are required.

— Let's discuss calculating the nutritional norm for a mixed-fed newborn?

— This is a situation in which the child’s diet contains both mother’s milk and formula. Most often, we recommend this feeding if the woman does not have enough milk and the baby is malnourished. Or when mom goes to work or is forced to leave home for other reasons.

The first question I always hear in this case is how to calculate the volumes and ratio of both products.

First, let's remember that breast milk comes first. And only after the baby has emptied the breast, it is the turn of the milk formula.

As for the volume: for milk, this is as much as the mother has. For the mixture: try diluting a third of the age norm and observe the child’s reaction. He ate everything and is full, doesn’t get capricious and falls asleep - that means that’s enough. If he is capricious and writhes his legs and arms, there is not enough food. Then next time dilute half the age norm and observe.

To prevent the baby from abandoning the breast in favor of formula, it is recommended to use a special supplementary feeding system - a tube, which is fixed at one end at the nipple, and the other is in a bottle with formula. This way the baby suckles at the breast, thereby stimulating lactation, but at the same time gets full thanks to the formula.

As for the regime, here it is no longer entirely on demand. Our task is to establish a regime close to that on which the artificial baby is.

— Olesya Vladimirovna, how to determine the daily amount of nutrition on artificial feeding?

— In this situation, the baby’s main diet consists of infant formula.

When artificial feeding, it is recommended to give the baby formula every 3-3.5 hours, and the night break should be 6 hours. Older children are fed 5 times a day. The amount of food also depends on the age of the child. As a rule, approximate numbers are on the packages of the mixture. They should not be final; they are used as recommendations.

If your baby does not eat the calculated amount of formula, feed him more often, albeit in smaller portions. This often happens in children born prematurely or who have a shortened frenulum of the tongue.

When calculating nutrition scientifically, several approaches can be used at once.

If we focus on height and weight, then we use the Reiche method for calculation. To do this, we use a simple formula - divide the child’s weight in grams by his height in centimeters and multiply by seven. This is how we get the daily volume of the mixture and then distribute it according to the number of meals.

Table: basis for calculating mixture by age

Also, when calculating nutrition by age, you can use Shkarin’s formula: a child at 2 months eats 800 ml of milk per day. For every week missing until this age, we subtract 50 ml, and for every month older we add 50 ml.

Formula for calculating the nutrition of a newborn:

where n is the number of months of life

Most mothers are concerned about the task of choosing the right baby formula. As a pediatrician, I’ll tell you what you need to focus on in this matter.

• the mixture must be adapted, that is, as close as possible in composition to a woman’s breast milk,
• nutrition should be according to age, and today there is a gradation of mixtures: 1 formula - up to 6 months, 2 formula - from 6 to 12 months, 3 formula - over 12 months,
• There are additional inclusions in the mixture, and I am in favor of choosing a mixture with additional “benefits”: nucleotides for immunity, lecithin for brain development, bifidobacteria for enriching intestinal microflora, and so on.

Now let's talk about the mode. When breastfeeding, nutrition is organized on demand, but when bottle-feeding, a regimen with optimal intervals is required. They are listed for each age on the food package. We recommend taking them as a basis, but adjusting them taking into account the individual characteristics of the baby.

Introduction of the first complementary foods

The composition of mother's milk fully satisfies the needs of the child's growing body up to 6 months, while adapted formulas, no matter how enriched with various microelements, are not fully absorbed, and the child already at 4-5 months needs an additional source of nutrients

. You can learn more about healthy nutrition for children by taking into account the fact that for bottle-fed children, complementary foods must be introduced a month earlier.

Let's consider additional, starting from six months, as with breastfeeding.

Despite the recommendations of pediatricians in past years, today you should not use applesauce or juice for the first complementary feeding, since its acidity can upset the balance of bacteria in the baby’s stomach and lead to diathesis. The best option for a baby’s first acquaintance with adult food would be to introduce potatoes or lighter zucchini during the season. It should be administered in the first half of the day, after the main intake of milk or formula, starting with a teaspoon and gradually replacing the second feeding with 80 - 90 g. vegetable puree. Gradually you can make multi-component purees, fruit purees and juices diluted with water.

When introducing new products, it is necessary to remember that the nutrition of children under one year old does not imply the use of artificial colors, trans fats and preservatives, therefore the best food is healthy food for children from a source that the mother is sure of.

Starting from the moment the baby reaches the seventh month, you can introduce fermented milk products prepared using special starter cultures and lactic bacteria. Such food will help the child quickly adapt to solid food and create the necessary microflora in the intestines. The diet of a seven-month-old child should include two full meals consisting of vegetable soup or puree, dairy-free porridge or kefir. The amount of cow's milk products should be limited, as it is a strong allergen in its pure form. By the end of the seventh month, the amount and composition of complementary foods for a breastfeeding baby and an artificial baby are equalized.

The diet of an eight-month-old baby becomes more varied, as chicken or rabbit puree, a quarter of an yolk and a little butter or vegetable oil are gradually introduced into the diet. A healthy diet for children should be varied and contain all the necessary substances for growth and development.

Dietary food for children under one year of age should not contain fried or smoked food; canned food, soups with meat broth and a variety of sweets are also prohibited. During the period when the child already has several teeth, and this usually happens by 9 months, you should not give the baby solid food, from which a piece may fall off. So carrots, apples and cookies, which children used to relieve itchy gums, become pathologically dangerous.

Questions

Artificial feeding is an accurate calculation of the amount of formula needed by the child. When bottle-feeding, you should feed the baby hourly, maintaining the necessary intervals between meals. And for one feeding it is necessary to give the baby a certain volume of formula. The frequency of feedings is determined by the age of the baby:

• For the first 10 days of life, a child should be fed 7–10 times a day;
• Child 10 days - 2 months - feed 7 - 8 times a day with a 6-hour break at night;
• Child 2 - 4 months - feed 6 - 7 times a day with a 6.5 hour break at night;
• Child 4 - 6 months - feed 5 - 6 times a day with an 8.5 hour break at night;
• Child 6 - 12 months - feed 4 - 5 times a day with an 8.5 hour break at night.

You should adhere to the above frequency of feeding the baby at different stages of his life. The frequency of feedings is determined by age, and the required amount of formula is calculated individually depending on the child’s body weight.

Currently, there are various ways to calculate the amount of formula needed by a formula-fed baby. The most common and convenient is the volume formula. The daily amount of formula required by the child according to the volumetric formula is shown in the table.

The table shows the daily amount of formula that a child needs for the whole day. In order to calculate how much formula a child needs per feeding, the daily volume should be divided by the number of feedings. In addition, the required amount of formula for a child in the first 10 days of life can be calculated using Zaitseva’s formula. Daily volume of formula = 2% of the child’s weight at birth in grams * number of days of life. For example, the daily volume of formula for a child on the 5th day of life, born with a weight of 2950 g = 2950 * 0.02 * 5 = 295 ml. This volume of the mixture is divided into 7 feedings = 295/7 = 42 ml. That is, a child needs 42 ml of formula per feeding. After the 10th day of life, the Shkarin formula or the calorie method is used to calculate the amount of formula needed by the child. Shkarin's formula is based on the postulate that at 8 weeks (2 months) the child should receive 800 ml of formula per day. If the child is under 8 weeks, then the amount of formula is calculated as follows: 800 - 50 * (8 - N), where N is the number of weeks of the child’s life. For example, a 5-week-old child needs the following amount of formula per day: 800 – 50 (8 – 5) = 650 ml. If the child is older than 2 months, then the amount of formula is calculated using the following formula: 800 ml + 50*(M – 2), where M is the number of full months of the child’s life. For example, a child 5 months of age needs the following amount of formula per day: 800 + 50 (5 – 2) = 950 ml. The calorie method is based on the energy needs of children, which up to 6 months are 115 kcal per 1 kg of body weight, and after six months - 110 kcal per 1 kg of the child’s body weight. Then, based on the child’s body weight and the calorie content of the milk formula (680 kcal in 1 liter), the volume the child needs during the day is calculated. For example, a 2-month-old child weighs 4.6 kg. This means that he will need kcal per day 4.6 kg * 115 kcal = 529 kcal. Then we calculate the volume of the mixture containing this amount of calories as follows: 520 * 1000/680 = 780 ml. Remember that the daily amount of food for children under 6 months should not be more than 1000 ml, and for infants older than six months - no more than 1100 ml.

How much formula should a baby take?

It is quite easy to calculate how much formula to give your child per day and how much to give at each feeding. There are many different ways. If you calculate based on the child’s age, an eight-week-old baby needs to consume 800 ml of milk per day. If the baby is less than eight weeks old, you need to give 50 ml less formula.

And if the child is older than eight months, the volume of the mixture should be increased by 50 ml every month.

You can also calculate the volume of the formula based on the weight of the child. During the first weeks of life, the child should consume 1/5 of his body weight per day. Over the next 2 months, already 1/6 part, if he is from 3 to 5 months - 1/7 part of body weight, and during the second half of the year the baby needs 1/8 part.

There is a technique that will help you calculate nutrition, knowing your body weight and height. The formula is this: you need to divide your weight in grams by your height in centimeters and multiply everything by 7.

Baby from 3 to 6 months – 110 calories per 1 kg. And from 6 to 12 months – 100-90 calories per 1 kg of weight.
