Feeding a newborn can feel like decoding a secret language. Every cry, wiggle, and fuss makes you wonder—are they hungry again? Did they eat enough? Am I overfeeding them? One of the most common questions new parents have is: how much should a newborn eat? Whether you’re breastfeeding, formula-feeding, or doing a mix of both, understanding your baby’s feeding needs in those early weeks can be both reassuring and life-saving.
Let’s break it down—how much breastmilk should a newborn eat, how much formula should a newborn eat, and how often should newborns eat? This guide answers all those questions and more with easy-to-understand explanations and practical tips.
Understanding Your Newborn’s Tummy
Why Newborns Eat So Often
Newborns have tiny stomachs—about the size of a cherry at birth. That’s why they can’t take in large amounts of food at once and need frequent feeding. So if you’re wondering how often should newborns eat, the answer is usually every 2 to 3 hours in the first few weeks. Some may feed even more frequently during growth spurts.
Hunger Cues to Look Out For
Before crying even begins, babies often show subtle hunger cues—rooting (turning head toward your breast or bottle), sucking on hands, or becoming more alert and active. Catching these signs early can make feeding smoother and more peaceful.
How Much Breastmilk Should a Newborn Eat?
The First Few Days
In the first 24–48 hours, your baby will likely take in just teaspoons of colostrum at a time, and that’s totally fine. By day 3 to 5, your milk comes in more fully, and feeding volumes increase. Source
Daily Intake by Age
So, how much breastmilk should a newborn eat in a day? Most newborns consume about 1.5 to 3 ounces (45–90 ml) per feed by the end of the first week, and this gradually increases.

Here’s a quick look at what to expect:
Day 1–3: 0.5 to 1 oz per feeding, 8–12 times/day
Day 4–7: 1 to 2 oz per feeding, 8–12 times/day
Week 2–4: 2 to 3 oz per feeding, 8–10 times/day

How Much Formula Should a Newborn Eat?
Formula Feeding Basics
Formula is digested more slowly than breastmilk, so formula-fed babies may space their feeds out slightly more. However, newborns still need about 8–10 feedings per 24 hours.
Ounces Per Feed
Wondering how much should a newborn eat when formula-fed? Typically, they’ll start with 1 to 2 ounces per feed in the first few days. By the end of the first month, most babies take around 3 to 4 ounces per feeding.
How to Tell if Your Baby Is Getting Enough
Steady weight gain, 6+ wet diapers a day, and contentment after feeding are all great signs. If your baby seems unsatisfied after every feed or is feeding too frequently or too rarely, it’s worth checking in with a pediatrician.
Feeding Frequency Explained
So, How Often Should Newborns Eat?
Breastfed newborns usually feed 8–12 times per day. Formula-fed babies might eat 6–10 times. These feedings might not follow a predictable pattern initially—it’s okay! Over time, your baby will settle into more regular rhythms.
Don’t Watch the Clock
Instead of timing every feed, focus on your baby’s hunger and fullness cues. Some feeds will be short, others longer. As long as your baby is thriving, you’re on the right track.
Tips for Stress-Free Feeding
Trust Your Instincts
No one knows your baby better than you do. If you’re worrying about how much should a newborn eat, remember that a happy, growing baby is your best measure.
Mix of Breast and Bottle? No Problem
Combination feeding is common, and it’s totally okay to mix breastmilk and formula. Just monitor total intake and feeding cues to avoid overfeeding.
Don’t Compare
Every baby is unique. How much should a newborn eat might differ even between siblings. Go by your baby’s needs, not others’ timelines.
Summary!
Feeding your newborn doesn’t need to be complicated. Whether you’re tracking how much breastmilk should a newborn eat, looking up how much should a newborn eat, or scrolling for the perfect how much breastmilk should a newborn eat chart, the most important thing is to respond to your baby’s cues and consult your pediatrician if in doubt.
Keep in mind how many ounces should a newborn eat varies with age, and how often should newborns eat can shift depending on growth and temperament. As long as your little one is healthy and gaining weight, you’re doing great.
