How much formula to feed baby by weight


Amount and Schedule of Baby Formula Feedings

  • ​In the first week after birth, babies should be eating no more than about 1 to 2 ounces (30 to 60 ml) per feed.
  • During the first month, babies gradually eat more until they take 3 to 4 ounces (90 to 120 ml) per feed, amounting to 32 ounces per day. Formula-fed babies typically feed on a more regular schedule, such as every 3 or 4 hours. Breastfed babies usually take smaller, more frequent feedings than formula-fed infants.

If your baby sleeps longer than 4 to 5 hours during the first few weeks after birth and starts missing feedings, wake them up and offer a bottle.

  • By the end of the first month: Your baby will be up to at least 3 to 4 ounces (120 mL) per feeding, with a fairly predictable schedule of feedings about every 3 to 4 hours.

  • By 6 months: Your baby will consume 6 to 8 ounces (180–240 mL) at each of 4 or 5 feedings in 24 hours.

Formula feeding based on body weight

On average, your baby should take in about 2½ ounces (75 mL) of infant formula a day for every pound (453 g) of body weight. But they probably will regulate their intake from day to day to meet their own specific needs, so let them tell you when they've had enough. If they become fidgety or easily distracted during a feeding, they're probably finished. If they drain the bottle and continues smacking their lips, they might still be hungry.

There are high and low limits, however. If your baby consistently seems to want more or less than this, discuss it with your pediatrician. Your baby should usually drink no more than an average of about 32 ounces (960 mL) of formula in 24 hours. Some babies have higher needs for sucking and may just want to suck on a pacifier after feeding.

On-demand feeding

Initially it is best to feed your formula-fed newborn a bottle on demand, or whenever they cry with hunger. As time passes, your baby will begin to develop a fairly regular timetable of their own. As you become familiar with their signals and needs, you'll be able to schedule their feedings around their routine.

Eating & sleeping patterns

Between 2 and 4 months of age (or when the baby weighs more than 12 lb. [5.4 kg]), most formula-fed babies no longer need a middle-of-the-night feedings. They're consuming more during the day, and their sleeping patterns have become more regular (although this varies considerably from baby to baby). Their stomach capacity has increased, too, which means they may go longer between daytime feedings—occasionally up to 4 or 5 hours at a time.

If your baby still seems to feed very frequently or consume larger amounts, try distracting them with play or with a pacifier. Sometimes patterns of obesity begin during infancy, so it is important not to overfeed your baby.

Getting to know your baby's feeding needs


The most important thing to remember, whether you breastfeed or bottlefeed, is that your baby's feeding needs are unique. No book―or website―can tell you precisely how much or how often they need to be fed or exactly how you should handle them during feedings. You will discover these things for yourself as you and your baby get to know each other.

Baby formula feeding chart: How much formula by weight and age

Is your baby getting too much or too little formula? It's an important question that worries many new parents, especially those with newborns. When deciding how much formula to give your baby, it's important to watch their hunger cues as well as looking at guidelines based on age and weight. In general, before they're eating solids, babies need 2.5 ounces of formula per pound of body weight each day.

These guidelines are for babies who are exclusively formula-fed for the first 4 to 6 months, and then fed a combination of formula and solids up to age 1. If your baby is getting a combination of breast milk and formula, talk to their doctor for separate advice.

Your pediatrician can tell you where your baby falls on the growth charts, make sure they're growing steadily on their own growth curve, and help you ensure that they're getting a healthy amount of formula. If you're ever worried about your baby's growth, behavior, or development, talk with their doctor.

How much formula for a newborn

For the first few days, offer your newborn 1 to 2 ounces of formula every 2 or 3 hours. (At first, newborns may only take a half ounce of formula at a time.)

After the first few days, give your newborn 2 to 3 ounces of formula every 3 to 4 hours.

Initially it's best to feed your formula-fed newborn on demand, whenever they show signs that they're hungry. Because your little one can't tell you when they want a bottle, you'll need to learn to read their hunger cues. Crying is often a late sign of hunger, so if you can, try to catch the earlier signs that it's time for a feeding.

Here are some hunger cues to watch for:

  • Smacking or licking their lips
  • Rooting (moving their jaw, mouth, or head in search of food)
  • Putting their hands to their mouth
  • Opening their mouth
  • Fussiness
  • Sucking on things
  • Becoming more alert
  • Crying

As time passes, your newborn will begin to develop a fairly regular feeding schedule. You'll become familiar with their cues and needs, and knowing when and how much to feed them will be much easier.

Formula feeding chart by weight

During the first 4 to 6 months, when your baby isn't eating solid foods, here's a simple rule of thumb: Offer 2.5 ounces of formula per pound of body weight every 24 hours, with a maximum of about 32 ounces.

7 pounds17.5 fl oz every 24 hours

9 pounds22.5 fl oz every 24 hours
10 pounds25 fl oz every 24 hours
11 pounds27.5 fl oz every 24 hours
12 pounds30 fl oz every 24 hours

These numbers aren't rigid rules. They offer a rough estimate for what your baby may need. Some babies will grow well while taking less than the recommended amount, while others consistently need more. Your baby's daily feedings will also vary according to their individual needs – in other words, they may want a bit more on some days and a bit less on others.

Formula feeding chart by age

Here are typical amounts per day based on age:

AgeOunces of formula
Full-term newborn2 ounces per bottle every 3 to 4 hours
1 month old3 to 4 ounces per bottle every 3 to 4 hours
2 month old4 to 5 ounces per bottle every 3 to 4 hours
3 month old4 to 6 ounces per bottle every 3 to 4 hours
4 month old4 to 6 ounces per bottle, 4 to 6 times a day
5 month old4 to 6 ounces per bottle, 4 to 6 times a day
6 month old6 to 8 ounces per bottle, 4 to 5 times a day
7 month old6 to 8 ounces per bottle, 3 to 5 times a day

From 8 months old until their first birthday, you can expect your baby to have 7 to 8 ounces per bottle, 3 to 4 times a day.

As your baby gets older – and their tummy gets bigger – they'll drink fewer bottles a day with more formula in each. It's important not to overfeed your baby so they'll stay at a healthy weight. Your baby shouldn't have more than 32 ounces of formula in 24 hours.

When they reach their first birthday, they can stop drinking formula and transition to cow's milk in a bottle, sippy cup, straw cup, or open cup. Limit your toddler to 16 to 24 ounces (2 to 2.5 cups) a day of whole milk, so they have room for other healthy foods.

Here are signs that your baby's getting all the formula they need:

  • Steady weight gain. They continue to gain weight after their first 10 days and follow a healthy growth curve during their first year. (Most babies lose up to 7 to 10 percent of their birth weight in the first few days and then regain it by the time they're about 2 weeks old.)
  • Happy baby. They seem relaxed and satisfied after a feeding.
  • Wet diapers. They wet two to three diapers a day in the first few days after birth. Over the next few days, the amount should increase to at least five to six wet diapers a day.

Babies are usually good at eating the amount they need, but bottle-fed babies can drink too much at times. Here are the signs that they're getting too much formula:

  • Vomiting after a feeding may be a sign that your baby had too much. (Spitting up is normal, vomiting isn't.)
  • Tummy pain after a feeding can also be a sign of overfeeding. If your baby draws up their legs or their tummy seems tense, they may be in pain. (See other possible reasons for stomach pain in babies.)

If your baby seems to want to eat all the time, even after finishing a bottle, talk to your pediatrician. Using a pacifier may help soothe their need to suck.

Formula-feeding tips

  • In general, babies eat when they're hungry and stop when they're full, so resist the temptation to encourage your baby to finish each bottle. Overfeeding during infancy can contribute to obesity later in life.
  • Don't respond to your baby's every cry with a bottle. They may be crying because their diaper is wet, they're cold or hot, they need to be burped, or they want to be close to you. (Learn more about why babies cry, and how to soothe them.)
  • Your baby may be hungrier than usual during growth spurts. These typically occur 10 to 14 days after birth and around 3 weeks, 6 weeks, 3 months, and 6 months of age.
