How much milk / formula should a newborn eat at one feeding and per day: formulas and tables for calculation

When establishing breast or artificial feeding, parents must bear in mind how much a newborn should eat at a time and a day. These data will help to organize the process correctly and will have the most beneficial effect on the physical development of the child.

In the first month of his life it is very important not to allow both overfeeding and fasting. Special formulas and tables will allow you to calculate the necessary dosages of baby food in each case, given the weight and age of the baby.


If the mother is configured to breastfeed, she just needs to know how much milk the newborn should eat, starting from the first days of life. This will allow her to remain calm and not be nervous in vain (after all, experiences will later affect the amount and quality of lactation). What indicators to rely on in this issue?

First feeding

The most exciting days for nursing women are the first three after the birth of the baby. After all, milk begins to arrive only on the fourth. So far only colostrum comes from the chest. And anxieties begin that in such a situation the newborn will remain hungry. In fact, you should not be afraid of this for the following reasons:

  1. The kid himself will not eat much, because the sucking reflex at this stage is very poorly developed, he will only learn from it.
  2. Yes, and his stomach is very small (volume - only 10 ml) and can not contain too much food.
  3. Colostrum, produced in the first days by the female body, is rich in fat and nutrition. Therefore, it has everything you need in order to ensure the full functioning of the newborn.
  4. On the fourth day, the amount of milk in the breast will naturally increase, so all these worries about its lack at first are only harmful and completely unjustified.

There is a very simple formula for how to calculate how much a newborn should eat in the first days of its life. The volume of his stomach = 10 ml. It is believed that at this stage he will need about 10 feedings for 24 hours. Accordingly, the daily dose = 100 ml. However, all these numbers will change significantly over the next week.

4-10 days

During this period, several other factors will influence how much the newborn eats:

  • the mammary glands of the mother will begin to produce much more milk;
  • the volume of the stomach of the baby will change, as it will grow by leaps and bounds, respectively, and the amount of fluid consumed will increase.

For the first 10 days of a newborn's life, there is a special formula for calculating how much milk a newborn should eat during one feeding:

  • N (how many days a baby has) x 10 = the volume of what the newborn ate, in ml at a time.

The problem of breastfeeding is that it is difficult to understand how much a newborn has eaten milk. The artisans can see everything perfectly: there was so much mixture in the bottle - so much was left. Calculate easily.

For infants, the amount of fluid they can drink can be determined only in one way. To do this, you need medical scales that are particularly accurate. The newborn must be weighed on them before and after feeding. The difference between the readings and will be the desired parameter.

1 month

After the tenth day, the mother at the intuitive level or on the basis of data obtained from regular weighings will know how much her baby eats at once. Does it conform to the norms? We calculate again by a special formula:

  • N (baby weight): 5 = volume eaten per ml per day;
  • V (volume in ml per day): P (number of feedings per day) = volume eaten in ml per 1 time.

The number of feedings is a very individual indicator. For artificially born babies it is much more convenient to make a schedule by the hour, because there is no milk tide factor in the breast, which needs to be controlled, but there is a recommended interval between feedings (at least 3 hours).

But for babies pediatricians consider the best option meals on demand. This will not allow milk to stagnate, will not lead to mastitis, and the baby will be cheerful and calm, because it will always receive the necessary amount of food.

Another important piece of advice to parents of babies: do not calculate how much he ate, according to the amount of time he spent at sucking. On average, it ranges from 15 to 30 minutes. But one child absorbs the necessary rate in 15 minutes, and the other in only half an hour. Someone even 40 minutes is not enough, because the intensity of sucking is different for everyone. Do not rush the crumb, but do not let him sit at the breast for more than an hour. And how to calculate the dosage for the artificialites?

According to research. As observations have shown, the last 5-10 minutes the newborn is sucking the breasts, not in order to filter out the milk from it. By this time, he is usually fed up. The reason - in the psychological comfort that the baby feels in these moments.

Artificial feeding

Is it even possible to calculate how much the mixture should be eaten by the newborn, if he is on artificial feeding? Yes, for such babies, formulas also work by which it is easy to determine the necessary dosages.

One of them will be exactly the same as for babies. The second is slightly different. For the daily amount used the same formula:

  • N (baby weight): 5 = volume of the mixture, which the newborn ate, in ml per day.

This is quite understandable, because, regardless of the type of food that a baby receives in the first month of its life, it must be full and the volume is the same. But in terms of the number of meals the formula will be slightly modified. Pediatricians are advised to space them for the artificials at least 3 hours. At night, the stomach must rest.

And no matter how much mummies would like to feed their baby on his first demand, more or less than 7 times a day, in this rigid framework, it won't work. Accordingly, the equation takes the following form:

  • V (volume of the mixture in ml per day): 7 = volume in ml per time.

Of course, each situation is purely individual. If on artificial feeding it is necessary for the baby more often (rarely it is not exactly impossible at that age) to give the mixture, then the formula works for babies:

  • V (volume of the mixture in ml per day): P (number of feedings per day) = volume of food in ml per 1 time.

And you end up with a figure of how much a newborn should eat at one feeding, if everything is fine with it, it is not sick and corresponds in development to its age.

It is very important not to leave the norm, because it is very easy to overfeed with a mixture. After all, it is easier to suck from a bottle than from a breast, and if there is also a big hole in the nipple, you can do nothing at all: a trickle of life-giving liquid will flow into the mouth itself.

So, dear mommies, cook only the amount of the mixture, which is supposed to eat a little hero at a time. To help - a few tables with indicators of the norm in accordance with age.

Helpful advice. Never force a newborn to drink forcibly due to him the rate for 1 feeding. Perhaps he will "get" this amount next time. Pay much more attention to how much he ate in one day.


Those values ​​that you calculate by the formulas, how much a newborn child should eat at one time and for a day of milk or a mixture, should be compared with the norm values. This will determine if he develops according to his age.

They are contained in a special table in which daily and single dosages are scheduled monthly for up to 1 year.

This is done so that parents can see the dynamics of changes and understand that with an increase in the weight of the baby and the amount eaten by them will increase proportionally. Starting from 5 months, complementary foods will be added (with which porridge it is better to begin feeding the child, read here) and the dynamics will stop.

On this table, it is easy to determine how many milliliters of the mixture a newborn should eat at a time and a day. It is clear that the breadth of indicators for 1 feeding is due to the fact that their number will vary per day. But too rigid and completely mobile parameters of the last column cause concern for those parents whose children do not fit into the standards of height and weight.

What do those who have a child in 1 month weighs 6 kg instead of 7? And if a miniature girl was born, who has such heredity, and by the first month of her life she weighs only 3.5 kg?

These cases are not pathological, but they have a place to be. That happens. How to determine the amount of the mixture or milk required for such unusual babies? The second table will help - it is more universal and convenient for such non-standard situations.

The naked eye can see the superiority of this table over the previous one, although many parents, whose children develop quite standardly, do not want to engage in complex calculations and use data from the first one.

The last question that may arise in the calculations: in all tables, the normal values ​​are given in milliliters. Does this unit of measurement coincide with grams? The formula is simple:

  • 1 milliliter = 1.03 grams.

The difference is insignificant, so you shouldn’t bother yourself with it. And finally, it is worth giving a few useful tips on dosages of baby food for the little ones.

On a note! The norms given in the last column of the first table are very conditional, not only because of the possible significant difference in weight, but also because of the sex of the child. Still, girls are usually not as large as boys, respectively, and they eat less food.

Useful tips

Formulas, tables, calculations, norms, tolerances, how much a newborn should eat at a time and per day - this should worry parents in the following moments:

  • in the first days of a baby's life;
  • if the mother is inexperienced and does not know how much milk or mixture to give to the baby;
  • if the baby is born prematurely;
  • if he has serious health problems.

These are those situations that require special control over the nutrition of the newborn by doctors and parents. And absolutely no need every day, after each feeding, weigh the baby, worry about fluctuations in weight and constantly look at these tables. The fact that he eats up can be understood by a number of factors:

  • he is calm, he cries a little and is hardly capricious;
  • he has a good dream;
  • no problem with weight gain;
  • he regularly goes to the toilet.

About overeating, you yourself will guess by the loose body, diathesis puffy cheeks, and at the next examination of the pediatrician you will hear that it would be necessary to reduce the volume of the mixture or milk, which you indulge your hero.

In the first month of a baby’s life, it is advisable to keep track of how much he eats a mixture or milk, and compare these figures with the norm. If the amount of food consumed per day is much less than the estimated figures, you need to find out the reasons.

It’s one thing if a baby weighs little and needs much less food than peers. And another - if the problem is in any disease that makes you know about yourself in this way. If the portions eaten exceed the norm, it is also worth thinking about future obesity, which is fraught with dangerous consequences for such crumbs.

So the amount of the mixture or milk consumed by the child per day plays an important role in its development and formation. Parents should pay sufficient attention to this aspect at first, but not to fanaticism.
