How many ounces to feed a newborn baby

Formula Feeding FAQs: How Much and How Often (for Parents)

Whether you plan to formula feed your baby from the start, want to supplement your breast milk with formula, or are switching from breast milk to formula, you probably have questions.

Here are answers to some common questions about formula feeding.

How Often Should I Feed My Baby?

Newborns and young babies should be fed whenever they seem hungry. This is called on-demand feeding.

After the first few days of life, most healthy formula-fed newborns feed about every 2–3 hours. As they get bigger and their tummies can hold more milk, they usually eat about every 3–4 hours. As babies get older, they’ll settle into a more predictable feeding routine and go longer stretches at night without needing a bottle.

Talk to your doctor if you have concerns about feeding your baby, especially if your baby is very small, is not gaining weight, or was born early (prematurely).

How Can I Tell When My Baby Is Hungry?

Signs that babies are hungry include:

moving their heads from side to side
opening their mouths
sticking out their tongues
placing their hands, fingers, and fists to their mouths
puckering their lips as if to suck
nuzzling again their mothers' breasts
showing the rooting reflex (when a baby moves its mouth in the direction of something that's stroking or touching its cheek)

Babies should be fed before they get upset and cry. Crying is a late sign of hunger. But every time your baby cries is not because of hunger. Sometimes babies just need to be cuddled or changed. Or they could be sick, tired, too hot or too cold, in pain, or have colic.

How Much Should My Baby Drink?

In the first few weeks, give 2- to 3-ounce (60- to 90-milliliter) bottles to your newborn. Give more or less depending on your baby’s hunger cues.

Here's a general look at how much your baby may be eating at different ages:

On average, a newborn drinks about 1.5–3 ounces (45–90 milliliters) every 2–3 hours. This amount increases as your baby grows and can take more at each feeding.
At about 2 months, your baby may drink about 4–5 ounces (120–150 milliliters) every 3–4 hours.
At 4 months, your baby may drink about 4–6 ounces (120-180 milliliters) at each feeding, depending on how often they eat.
By 6 months, your baby may drink 6–8 ounces (180–230 milliliters) about 4–5 times a day.

Watch for signs that your baby is hungry or full. Respond to these cues and let your baby stop when full. A baby who is full may suck with less enthusiasm, stop, or turn away from the bottle.

Why Does My Baby Seem Hungrier Than Usual?

As babies grow, they begin to eat more at each feeding and can go longer between feedings. Still, there may be times when your little one seems hungrier than usual.

Your baby may be going through a period of rapid growth (called a growth spurt). These can happen at any time, but in the early months are common at around:

7–14 days old
between 3–6 weeks
4 months
6 months

During these times and whenever your baby seems especially hungry, follow their hunger cues and continue to feed on demand, increasing the amount of formula you give as needed.

Is My Baby Eating Enough?

At times, you may wonder whether your baby is getting enough nutrients for healthy growth and development. Babies who get enough to eat seem satisfied after eating and are regularly peeing and pooping.

At your baby’s checkups, the doctor will review your baby’s growth chart, track your little one’s development, and answer any questions. Talk to your doctor if you have any concerns about your baby’s feeding and nutrition.

How Often and How Much Should Your Baby Eat?

By: Sanjeev Jain, MD, FAAP

One of the most common questions new parents have is how often their baby should eat. The best answer is surprisingly simple: in general, babies should be fed whenever they seem hungry.

How do I know when my baby is hungry?

For babies born prematurely or with certain medical conditions, scheduled feedings advised by your pediatrician are best. But for most healthy, full-term infants, parents can look to their baby rather than the clock for hunger cues. This is called feeding on demand, or responsive feeding.

Hunger cues

A hungry baby often will cry. But it's best to watch for hunger cues before the baby starts crying, which is a late sign of hunger and can make it hard for them to settle down and eat.

Some other typical hunger cues in babies:

Licking lips
Sticking tongue out
Rooting (moving jaw and mouth or head in search of breast)
Putting his/her hand to mouth repeatedly
Opening her mouth
Fussiness
Sucking on everything around

It is important to realize, however, that every time your baby cries or sucks it is not necessarily because he or she is hungry. Babies suck not only for hunger, but also for comfort; it can be hard at first for parents to tell the difference. Sometimes, your baby just needs to be cuddled or changed.

General guidelines for baby feeding

It is important to remember all babies are different―some like to snack more often, and others drink more at one time and go longer between feedings. However, most babies will drink more and go longer between feedings as they get bigger and their tummies can hold more milk:

Most newborns eat every 2 to 3 hours, or 8 to 12 times every 24 hours. Babies might only take in half ounce per feeding for the first day or two of life, but after that will usually drink 1 to 2 ounces at each feeding. This amount increases to 2 to 3 ounces by 2 weeks of age.
At about 2 months of age, babies usually take 4 to 5 ounces per feeding every 3 to 4 hours.
At 4 months, babies usually take 4 to 6 ounces per feeding.
At 6 months, babies may be taking up to 8 ounces every 4 to 5 hours.

Most babies will increase the amount of formula they drink by an average of 1 ounce each month before leveling off at about 7 to 8 ounces per feeding. Solid foods should be started at about 6 months old.

Concerns about overfeeding or underfeeding your baby

Too full?

Babies are usually pretty good at eating the right amount, but they can sometimes take in more than they need. Infants who are bottle feeding may be more likely to overfeed, because drinking from a bottle may take less effort than breastfeeding.

Overfed babies can have stomach pains, gas, spit up or vomit and be at higher risk for obesity later in life. It's better to offer less, since you can always give more if your baby wants it. This also gives babies time to realize when they're full.

If you are concerned your baby wants to eat all the time―even when he or she is full―talk with your pediatrician. Pacifiers may be used after feeding to help sooth healthy-weight babies who like to suck for comfort, rather than nutrition. For babies who are breastfed, it's best to wait to offer pacifiers until around 3 to 4 weeks of age, when breastfeeding is well-established.

Trouble gaining weight?

Most babies will double their birth weight by 5 months of age and triple their birth weight by their first birthday. If your baby is having trouble gaining weight, don't wait too long between feeding―even if it means waking your baby. Be sure to talk with your pediatrician about how often and how much to feed your baby.

How do I know if my baby is getting enough to eat?

Daily diapers

A newborn's diaper is a good indicator of whether he or she is getting enough to eat. In the first few days after birth, a baby should have 2 to 3 wet diapers each day. After the first 4 to 5 days, a baby should have at least 5 to 6 wet diapers a day. Stool frequency is more variable and depends whether your baby is breastfed or formula fed.

Growth charts

During regular health check-ups, your pediatrician will check your baby's weight and plot it on a growth chart. Your baby's progress on the growth chart is one way to tell whether or not they are getting enough food. Babies who stay in healthy growth percentile ranges are probably getting a healthy amount of food during feedings.

Remember

Talk with your pediatrician if you have any questions or concerns about your baby getting the right amount to eat.

Breastfeeding on demand

You can often hear from a nursing mother: "I feed on demand, my baby requires a breast every 3.5 hours." Or: “I have always fed on demand. In a year, we already had 1 feeding in the evening, and my child calmly refused to breastfeed. Before talking about the demand of the child, it is necessary to find out what modern women mean when they say - "I breastfeed."

Modern mothers consider breastfeeding necessary for feeding their baby. Just for feeding. Breast milk is food, the mother supplies the baby with the nutrients necessary for growth and development. When a baby suckles at the breast, he eats. Breastfeeding makes sense only as a process of supplying proteins, fats, carbohydrates, vitamins and microelements.

During suckling, the baby receives the nutrients it needs with mother's milk. This is the absolute truth. There is another unconditional truth, which is not given any importance in modern society, it is not taken into account and is not considered. Breastfeeding for a child is communication with the mother. We need to figure out how the child understands feeding on demand? Can he understand anything at all? Is there any difference for him how he is fed, for 15-20 minutes after 3.5 hours or in some other way?

What is on-demand feeding

On-demand feeding of a newborn baby means putting it to the breast for every squeak or search. Squeak and search movements in newborns, even as early as the second or third day of life, begin to appear much more often than after 3.5 or 2.5 hours. The need for attachments increases rapidly, and by the 10-12th day of life, the need to attach to a child may occur 15-16 or more times a day. Applications vary in duration. The baby can fall asleep and sleep while sucking for, for example, 1.5-2 hours. Can release the breast after 1-2 minutes. And then ask her again. Why does a child need such frequent contact with his mother's breast?

That's why. Being in the mother's belly, in a calm, familiar environment, listening to the noises of the mother's body, being in a warm, cramped, confined space, the baby sucked his fist, fingers, loops of the umbilical cord, swallowed amniotic fluid. Learned to suck and swallow. After birth, experiencing discomfort for any, the most insignificant reason, the baby tries to get rid of it. You can get rid of discomfort by getting into the usual conditions of a comfortable stay. The only place where the baby after birth can feel the sensations familiar to him is in the arms of the mother. The only familiar action is sucking. The only familiar taste and smell is the taste and smell of milk and lube in the areola. Milk and lubricant have an odor and taste similar to the taste and smell of amniotic fluid. Therefore, experiencing discomfort, the baby squeaks, or begins to look for an object to suck with his mouth. Ideally, it is immediately applied to the chest. The baby becomes warm, cramped, he hears the beating of his mother's heart, breathing, grumbling in the intestines, he sucks and feels the familiar taste and smell. If such an action happens constantly, the baby gains confidence, no matter what happens, he will solve all his problems with his mother. The place of comfort is now under the breast, and you can suck on the breast.

This whole process is biologically justified. A newborn child does not feel the feeling of hunger, this feeling is not formed in him. It will begin to form at about two months of age. How to feed a creature that does not experience hunger ?! How to encourage him to take some action to get food? This can be done only at the expense of some other incentives. This stimulus for the newborn is constant bodily discomfort, thanks to which he wants to suckle all the time! The most intense, frequent and prolonged sucking in infants is observed in the first two or three months of life. It is in these first months that the main weight gain of the baby occurs.

Feeding in the first month

Baby falls asleep with breast in mouth, sleeps sucking for a while. Falling asleep deeply, lets go of the chest. After sleeping for a while, he wakes up, and is applied on waking. After sleep, he can stay awake for some time, for example, an hour and a half. During wakefulness, he may feel discomfort 2-3 times, for example, from a completely natural desire to pee, and having called his mother for help, having kissed for a couple of minutes, he will do his deeds. Then he will want to sleep, feel discomfort and, kissing his chest, will again fall asleep sucking. After some time, he will wake up and attach again. Then again a little "walk". And after some time, he will fall asleep at the chest again.

The daytime naps of a one-month-old infant feeding on demand vary in duration and number. There can be 4-6 dreams during the day, and they can last from 5-15 minutes to 2-2. 5 sometimes 3 hours. "Around" each dream, the baby is applied to the chest, and applied between dreams several times. At night, the child falls asleep at the breast. Usually in the early morning hours, he begins to fuss and apply. In the morning, he almost never fully wakes up. The baby sleeps, from time to time, sucking on his mother's breast. Waking up in the morning, the baby is again applied to the chest. If you count all the attachments that have happened in a baby of one month of age, then approximately 16-20 attachments are obtained. This is how a newborn human cub behaves if it is given the opportunity to behave in accordance with physiological and psychological needs, which, by the way, are genetically determined. The child of the first months of life does not separate his personality from the personality of the mother and from her breast. Mom and her breasts, and everything connected with them, are the universe of the baby and himself.

In most cases, a modern woman, being afraid to “accustom a child to hands”, strives to limit his requests for suckling. A pacifier and a bottle of tea or water come to her aid in this matter. They, too, can be sucked ... The need for sucking seems to be satisfied. But only the need for communication with the mother during suckling is not satisfied, the peculiar chain of mutual assistance and cooperation between mother and baby is destroyed, the formation of maternal affection and concentration is disrupted. Is the difference in the two actions noticeable to the reader: the baby cried, the mother took him, put him to her chest and started rocking him, or gave him a pacifier and started rocking the stroller, even with the words “Why are you crying, my sun?”

The modern woman who gives a pacifier and pumps a stroller is not a bad person deliberately harming an infant. She is simply in captivity of prejudices regarding the relationship between mother and baby. She does not know how to behave correctly, does not know what to do in accordance with the natural needs of the child. If you tell her what the child really needs, she will exclaim in horror: “What is it, don’t let him get away with?!” Indeed, the child of the first months of life must not be let off the hook. For a woman who does not know how to comfortably carry a baby, and who does not know how to feed him in various positions (sitting, lying, standing and even moving), this can be very difficult. Especially if she is not sure of the correctness of her actions.

An action that should become automatic for the mother of a newborn: when the baby cries or shows other signs of anxiety, put the baby to the breast.

What's next?

The baby is growing. A fairly stable rhythm of daytime sleep begins to form in him, and a 3-4-month-old baby behaves quite differently from a newborn. Feeding on demand at this age looks something like this...

At three months, the baby has 10-12 feeds during the day and 2-4 at night. There are frequent applications for a short time, but their number is reduced. There may be a long night break in feedings, about 5 hours, but this is very rare. Much more often the night break is 2.5-3.5 hours. By this age, the baby's body is noticeably rounded.
At four months, the baby begins to breastfeed noticeably less frequently. The main feedings are associated with sleep: the baby suckles before bedtime, during awakening and during sleep, both daytime and nighttime. In this regard, he has a fairly accurate feeding regimen. And many babies stop breastfeeding when they wake up after daytime sleep, sometimes as early as 2.5-3 months.
At five months, the baby has 8-10 daytime feedings and 2-3 nighttime, attachments as well as in the fourth month of life, are organized around dreams - the baby eats when going to bed and some babies suck during awakening.
At six months, the feeding regimen changes. The most active sucking shifts to the last 2-3 hours before waking up from a night's sleep. The period of daytime wakefulness can be divided into two periods: in the morning, when the baby sucked during the night is rarely applied to the breast, and in the evening, when attachments become very frequent. In total, there can be 7-10 day applications and 3-4 night applications. At this age, the baby begins a period of acquaintance with new food - pedagogical complementary foods. Sometimes there are attachments associated with the introduction of complementary foods, the baby “washes down” samples of new food with mother's milk. But many children do not want to drink complementary foods. When complementary foods are introduced to an on-demand baby, it is never meant to replace feedings with complementary foods. This is practically impossible, because the main feedings of the baby are associated with sleep, and mother's breakfasts, lunches and dinners, during which the baby gets acquainted with new food, are located between the baby's dreams, during his wakefulness.
At seven months, the frequency of application is about the same.
At eight months, the feeding regimen changes. Since the baby shows high motor activity and is very busy exploring the surrounding space, in the daytime he forgets to breastfeed. In this regard, the number of daily feedings can be reduced to 6-8 times. The baby compensates for the reduction in daytime feedings by increasing the frequency and duration of nighttime feedings up to 6 times.
In the second half of the year, babies who stopped breastfeeding when waking up after daytime naps recall this habit again. The baby’s daytime sleep in the second half of life, as well as in the region of a year and older, looks something like this: the baby falls asleep sucking, sleeps quietly for a while, for example 1-1.5 hours, then starts tossing and turning, fiddling, worrying, at this moment the mother lies down next to , gives him a breast and the baby can fill up 10-15-30 minutes sucking. Mom may well use this time for her own rest - lie down, read, while the baby sleeps while sucking. I know my mother, a lover of embroidery, who used this time specifically for embroidery ...
Breastfeeding becomes more frequent at nine to ten months. In the daytime, this is 4-6 full feedings and about the same number of attachments for various reasons. The baby has new reasons for attachment. If, during active actions to explore the world, the baby stuffs a bump or gets scared, he calms down with his mother's breast. There may be situations when you can comfort the baby by sitting next to him and hugging him. At night, 4-6 feedings remain, the baby begins to suckle more actively in the morning between 3 and 8 hours.
At eleven months, a baby can already have 2-3 complete complementary foods. Initiation to adult food in the mind of a child is not associated with breastfeeding: attachment to the mother's breast is something other than the desire to get enough of the product they like. As a rule, after the baby has eaten, he feels the need to attach himself to the breast. The number of daily feedings remains the same in the child, but the number of short-term attachments increases. There are active mid-morning feedings between 4 and 8 o'clock in the morning.
At ten or twelve months, the baby, if he is already walking, can sometimes breastfeed every time he comes to his mother, i. e. about every 15-30 minutes. Attachments around dreams and night sucking persist. Therefore, if a mother says that a child suckles once or twice a day, this means that there is no feeding at the request of the child. There are restrictions imposed by the mother, with which the baby has come to terms. He treats breast sucking like food, sucks on a pacifier or a finger to fall asleep or soothe, or falls asleep just like that, without calming down.
At twelve months, the baby is applied in about the same way.
At the age of one and a half years, there may already be one daytime nap, so there are fewer attachments associated with sleep. Preserved for morning sucking. The baby is very free with his mother's breasts. Sometimes it happens that he comes up to suck just for pleasure. For example, like this: he comes up, climbs on his knees, looks into his mother’s face, smiles, starts to swarm in his shirt, gets breasts, smiles at his breasts, sucks for 30 seconds and leaves.

As for the number of feedings per day when feeding a child on demand, their number is almost never less than 12. A newborn has 12 or more attachments, mostly they are all associated with dreams. And a child, say 1.5-2 years old, can also have about 12 attachments, only 3-4 are associated with sleep, and the rest are short-term attachments for various reasons. I suggest to all mothers reading this text - do not count the application, do not notice their duration. Breastfeed your baby as often as he asks, when you feel the need to.

Moms who don't think about breastfeeding without looking at the clock may get the impression that when breastfeeding on demand, the mother can do nothing but feed the baby. This is not true. After the birth of a baby, a mother begins another life, she is called life with a baby. That's all. The child is with the mother, not the mother with the child! Feel the difference! You need to be able to organize your life in a different way, in the first months, of course, the help of loved ones is very necessary. In the tradition of many peoples, it was customary for the first 40 days after childbirth to remove a woman from any housework and household chores, she was engaged only in a child. In some nations, objects that the mother of a newborn touched were considered “unclean”, therefore, they preferred to protect the mother from the rest of the household, allocating her a separate “corner” of the house, where no one bothered her and she did not interfere with anyone. Among the Slavs, such a restrictive custom was called a six-week. By 1.5-2 months, the rhythm of daytime dreams begins to form, and the baby has a kind of “regime”, the mother becomes more free.

For a mother who can't imagine breastfeeding without looking back at the clock, and who is sure that the “right” baby is the baby lying quietly in her crib all the time, feeding on demand will be a complete hassle. It will be much easier for such a mother if she stops looking at the clock and ties the baby to herself with a large scarf or uses a patchwork holder (sling). It will become easier for her if she stops running between the nursery and the kitchen, but takes the baby with her to the kitchen and carries him around the house with her, doing housework, in a box, a cradle, a special chair, if she tries not to put him off often, and pick up as soon as possible, postponing the baby only in case of emergency and not for long.

Breastfeeding is not the same as house arrest. In the conditions of modern society, it is possible to organize the exit of a nursing mother to work from about 6 months of age of the baby. If necessary, you can start working from the age of 4 months, but, of course, it is better not every day of the week and not full time. It is the responsibility of a breastfeeding consultant to help a mother organize her return to work.

Sometimes, when I advise mothers on breastfeeding, I suggest that they forget for a second that they are already living in the 21st century. I propose to return, for example, to the cave and ask what they will do if the child woke up at night, how to calm him down? If you are walking through the forest and trying not to attract the attention of predators, how to make the baby silent? If the child is thirsty, what will you give him? What is the baby used to, for thousands of years of its existence? To the fact that he sleeps on his mother while she wanders through the forest with a digging stick in search of roots, and wakes up when mother stops. Since mom stopped, then there is time to wake up and suck. Therefore, even now the child sleeps well, tied to the mother with a patchwork holder, wakes up when the mother, having done a few household chores, sits in a chair to take care of the baby.

Some mother, reading about the cave, will be offended, saying that she is a civilized creature. But please think. Man, mother's breast and mother's milk have been created by evolution over millions of years. They are made for each other. Baby food has created progress and more recently. The skills of motherhood and breastfeeding have also been lost by our society quite recently. A person is not physiologically adapted to artificial feeding and a pacifier. The mother's breast will not produce enough milk at 6-7 feedings per day. Nature did not know, when creating man as a mammal, that the time would come when the need for breastfeeding would be satisfied by some kind of pacifiers and nipples.

Changes that occur during the formation of the personality of a child who did not have full contact with the mother during prolonged breastfeeding are noted by modern research by psychologists and sociologists. These are changes with a minus sign. It would be better if they were not, these changes.

Breastfeeding is important not only for the baby, it is also important for the mother. During on-demand feeding, the woman's feelings change, a stronger attachment to the baby is formed, the woman becomes more sensitive to the needs of the baby. Deeper affection and understanding are not only preserved in infancy. They persist for life. For clarity, imagine what happens to a woman’s feelings if she tries to “withstand” a child, endures his crying, anxiety. What happens to a woman if she uses the recommendation from one very popular parenting book: "Go to the child if he cries for more than 15 minutes"? Speaking in abstract terms, humanity is interested in reviving the practice of breastfeeding. The revival of this practice is impossible without mothers realizing the true reasons for the child's need for attachment to the breast.

Like every new mom, you're probably wondering, "How often should a newborn eat?" and “How many milliliters does a newborn baby drink at a time?”. A mother's body is designed to provide her baby with all the nutrients she needs, but every mom needs practical advice and confidence when it comes to how much milk a newborn should drink.

Whether you are breastfeeding, bottle feeding or a combination of both, here you will find all the information you need to know how much food your baby needs to grow and develop properly.

Signs that the child is hungry

Every mother has a great maternal instinct, but we cannot guess the desire of the child from the first time. Over time, you will learn your child's unique gestures and body movements, as well as signs that he is hungry. In the meantime, here are some of the most common signs that a baby is hungry:

turns head towards your breast or bottle;
clenches her fists;
puts pens in mouth;
pouts, smacks or licks lips.

If your child is showing any of these signs, they may be trying to tell you it's time to eat. Ideally, your baby should be fed on demand when he is hungry. If you're breastfeeding, on-demand feeding is a good way to keep your milk supply going as your body will naturally respond to your baby's needs and continue to produce the required amount of milk. Bottle-feeding on demand can also be beneficial for your baby, as it allows him to self-regulate his feeding needs.

How much breast milk should a newborn drink?

So, how much should a newborn baby eat? A remarkable feature of each child is its uniqueness, so it would be wrong to feed the baby strictly according to the instructions. Don't panic if the recommendations below don't fit your own feeding schedule, but please contact your healthcare provider or pediatrician if you have any questions.

Although all babies are different, newborns typically eat every two to three hours, for a total of 8 to 12 meals a day.

How many milliliters does a newborn baby drink? At the very beginning, your body will only produce a small amount of yellowish and thick breast milk called colostrum. This milk is an ideal source of nutrients that your newborn needs, in addition, it has many immunological components. ¹

How much milk does a newborn baby drink? Infants drink 30-60 ml per feeding, while this volume increases to 60-90 ml by two weeks of age. So don't worry if you don't feel like your body is producing much milk in those first few days after your baby is born! Feeding times will also vary, ranging from 10 to 30 minutes at the very beginning and then gradually increasing as your baby grows.

How much breastmilk the baby takes if bottle feeding

If you choose to bottle feed your baby from time to time, do so at the same intervals and for the same period of time as if you were breastfeeding. Pumping is a great option for breastfeeding your baby. It will allow you to separate from the baby if necessary and at the same time retain all the benefits of breastfeeding.

It's also important to get a bottle that helps make bottle feeding more natural for both you and your baby.
