How many ounces do you 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.

How many ounces should a newborn eat?

Overview

Let's be honest, newborns don't do much. Eat, sleep and poop, and then sleep, eat and poop again. But don't be fooled by your little one's free schedule.

In fact, your baby does important work in the first few weeks of life. All this sleep and food helps them grow at an amazing rate.

But you might be wondering how much your newborn really needs to eat. Here is a feeding guide for new parents.

How much should newborn babies eat on their birthday?

You may be worried about getting your child to eat as soon as possible. But on the first day of life, your baby may be just as tired as you are after giving birth.

It is not uncommon for babies to be very sleepy in the first 24 hours of life. That first 24-hour period after birth can be a learning curve for a baby to literally learn how to eat and be mindful enough to eat. Don't worry too much if your child doesn't show interest in eating every two hours on a schedule.

One study found that, on average, breastfed babies ate about eight meals and wore three wet or dirty diapers in the first 24 hours of life. This is less than they will eat and put away later.

You may be shocked to see how little your newborn actually eats during breastfeeding on the first day of life. This is normal, so don't worry. Keep in mind that until you have milk (around the third day after giving birth), your baby will only drink colostrum.

Colostrum is like a concentrated superfood, full of calories and nutrients, so even small amounts are sufficient for the first couple of days. Think quality, not quantity.

The average healthy newborn only drinks about 1/2 ounce of colostrum during the first 24 hours of life. Of course, all children are different.

When should I start feeding a newborn baby?

Newborns are especially active an hour or two after birth, so it is important to start breastfeeding as early as possible. If you skip this very active stage, your baby may become more sleepy later, making it difficult to practice latch on for the first first feed.

If your baby does not show signs of wanting to breastfeed, you should continue to breastfeed your baby every two to three hours. This can take a lot of practice, so it's important to be patient while your baby figures out the best way to breastfeed.

Write down the feeding times and the number of wet and dirty diapers your baby has during your hospital stay. Your nurse and doctor will be able to help you determine if your baby needs extra support to breastfeed or supplement.

Feed by Weight

As a rough estimate, your child should eat 2.5 ounces for every pound of their weight. Thus, if your child weighs 10 pounds, he should eat a total of 25 ounces per day.

How many ounces do formula-fed babies need each day?

The American Academy of Pediatrics (AAP) explains that after the first few days, your formula-fed newborn will drink 2 to 3 ounces (60 to 90 milliliters) of formula at each feeding.

They need to eat about every three to four hours. This is compared to a breastfed baby who typically eats every two to three hours.

By the time your baby is 1 month old, he should be eating about 4 ounces every four hours.

How much should breastfed babies eat?

If you are exclusively breastfeeding, you will not measure your baby's ounces for feeding. Instead, you will simply feed your baby on demand or when he wants to eat.

A newborn will typically eat every two to three hours during the first months of life, but this may vary. The feeding schedule starts from the moment your baby starts suckling.

For example, in the first few weeks, if your baby starts eating at 2:40 and breastfeeds for 4 minutes, he may be ready to eat again at 2:40. Hello breast milk bar!

Sometimes your baby may breastfeed more or less. Your baby may want to breastfeed more if he is sick. Nursing is a comfort mechanism and an immune booster. They may want to eat more if they are experiencing a growth spurt and need extra calories.

Both the AAP and the World Health Organization recommend breastfeeding on demand. So don't worry, you can't overfeed an exclusively breastfed baby.

Your baby will signal to you when he is full by pushing off or stopping by himself until he is ready again. And if you're an exclusive pumper, follow self-care routines to keep your milk supply going and watch your baby's signals about how much to feed.

Next Steps

It is best to feed your baby when he is hungry rather than following a strict schedule. Work with your doctor to make sure your child is growing and developing properly.

Q:

How do you know if you are feeding your baby properly?

Patient Anonymous

A:

Your baby will show signs of being full, showing less interest in milk and withdrawing. Do not force your child to eat more than he is interested if he continues to grow well. One of the signs that you are feeding too much is that your baby is spitting up a lot at every feed. If this happens even without overfeeding, be sure to ask your pediatrician about it. During your pediatrician visit, discuss how well your child is growing in weight and height. Steady growth along the growth curve is always a good sign that your child is eating a healthy amount of food.

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 the two, here you will find all the information you need to know about how much food your baby needs to grow and develop properly.

Signs indicating that the child is hungry

Every mother has a wonderful maternal instinct, but we cannot guess the child's desires 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 child is hungry:

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

If your child is showing any of these signs, they are probably 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 every baby is 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 eats if bottle fed

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 is also important to purchase a bottle that will help make bottle feeding more natural for both you and your baby.
