How Many Ounces Are Newborns Supposed To Eat? | Get It Right

Newborn feeding: start with 1–2 oz every 2–3 hours in the first days; by about 1 month most take 3–4 oz per feed, with formula intake rarely over 32 oz a day.

Newborns don’t read charts. Some take tiny, frequent sips. Others drain a bottle, then nap. Milk moves through small bellies fast, and appetite shifts with sleep, growth, and how feeds are delivered. The aim isn’t a perfect number. It’s steady growth, content stretches between feeds, and plenty of wet diapers.

How Many Ounces Should A Newborn Eat Per Feeding: Daily Guide

Most families ask the same thing during week one: “How many ounces per feed is normal?” Use the ranges below as a starting map for the first month, then let your baby’s cues steer day to day. For formula, the AAP’s formula guide and the CDC’s how-much/how-often page both echo these patterns.

Typical Newborn Intake & Frequency (First Month)

Age Window Ounces Per Feed Feeds In 24 Hours
First 24–48 Hours 1–2 oz Every 2–3 hours
Days 3–4 1.5–2.5 oz Every 2–3 hours
End Of Week 1 2–3 oz 8–12 feeds
Weeks 2–3 2–3 oz About every 3 hours
Week 4 3–4 oz Every 3–4 hours

Breastfed Newborns: What Those Ounces Really Mean

You can’t see ounces at the breast, and that’s fine. Early on, colostrum arrives in small volumes yet packs dense nutrition. Frequent nursing helps milk supply settle in and gives babies many chances to practice a deep latch. Expect 8–12 feeds a day, with intervals that stretch as weeks pass. Cluster feeding shows up too—brief runs of back-to-back nursing that often land in the evening.

Hunger And Fullness Cues

Watch the baby, not the clock. Early hunger looks like stirring, rooting, hand-to-mouth moves, lip smacking, or light fussing. Crying is a late cue. Fullness shows up as relaxed hands, slowed sucking, turning away, or drifting to sleep at the breast or bottle. Feeding to these signals trims overfeeding risk and keeps intake aligned with need.

How To Tell Your Breastfed Baby Is Getting Enough

Diapers and weight are your daily dashboard. After the first few days, most babies have at least six wet diapers and regular soft stools. Weight dips a little after birth, then climbs at a steady clip across the first months. If output drops or weight lags, ask your pediatrician and a trusted lactation pro to watch a feed and help tune latch, position, and any pumping plan.

Formula-Fed Newborns: Ounces And Daily Totals

Bottles make ounces visible, which is handy, yet the same cue-led idea still applies. In the first days, many newborns take 1–2 oz every 2–3 hours. By the end of the first month, many finish 3–4 oz per feed, with about 24–32 oz across a day. A simple guide is about 2.5 oz of formula per pound of body weight in 24 hours, with an upper limit near 32 oz for most babies. If a baby is draining every bottle and still acting hungry, add an ounce. If they’re pushing the nipple out or dozing after a small volume, shrink the next bottle and slow the flow.

Paced Bottle Feeding Helps

Fast flow can prompt gulping and bigger volumes than a baby truly wants. Try paced feeding: keep the bottle level, offer pauses, and switch sides mid-feed. This slows intake, keeps self-regulation on track, and mimics the rhythm of the breast. Burp midway and at the end. If coughing or leaking is frequent, move to a slower nipple flow.

Weight-To-Ounces Rule Of Thumb (Table)

Baby Weight (lb) Approx. Formula Per Day (oz) Sample Day Plan
6 lb 15 oz/day 2.5–3 oz × 6–7 feeds
7 lb 17–18 oz/day 3 oz × 6 feeds
8 lb 20 oz/day 3–3.5 oz × 6–7 feeds
9 lb 22–23 oz/day 3.5 oz × 6–7 feeds
10 lb 25 oz/day 4 oz × 6 feeds
11 lb 27–28 oz/day 4–4.5 oz × 6 feeds
12 lb 30 oz/day 5 oz × 6 feeds

Night Feeds, Growth Spurts, And Cluster Feeding

Most newborns feed around the clock. Short nighttime stretches are common, then feeds space out as stomach capacity grows. Brief surges in appetite often land near 2–3 weeks and again around 6 weeks. During these spurts, babies may want extra ounces or extra sessions. Lean into it; intake soon steadies again.

Common Scenarios And Simple Fixes

  • My baby sucks down a bottle in five minutes and spits up. Try a slower nipple and paced feeding. Offer a brief break every ounce.
  • My baby never finishes bottles. Check the nipple flow and feeding position. Some babies just prefer smaller, more frequent feeds.
  • My baby wants more than 32 oz a day. Call your pediatrician to review growth and whether larger feeds make sense right now.
  • My baby seems hungry again after 30 minutes. That can be a growth spurt or just a need to suck. Try skin-to-skin or a clean pacifier after the feed.

Safe Prep And Warming Basics

Wash hands. Use clean bottles. Mix formula as the label states. Make fresh bottles for each feed when you can, or refrigerate right away and use within the time on the product. Warm bottles in a cup of warm water or a warmer. Skip the microwave. Test drops on your wrist before you feed. Toss leftovers after an hour at room temp.

When Intake Looks Too Low

Newborns who are sleepy from a long stretch may need a gentle wake for feeds. Look for feeding cues at least every 2–3 hours in the early days. If latching is painful, milk transfer may be poor. Ask your pediatrician and a lactation pro to watch a feed and tune latch, position, and any pumping plan. If bottles are in the mix, paced feeding and the right nipple flow can help a baby finish without gulping air.

When Intake Looks Too High

Big volumes don’t always mean better growth. Signs of overfeeding include frequent spit-up, gassiness, arching, or fussing soon after feeds. Shrink bottle size by an ounce and slow the flow. Stretch the next feed by a short walk, diaper change, or a cuddle. Use a pacifier for non-nutritive sucking needs once breastfeeding is established.

How Much Ounce Talk Changes Over Time

Across the first month, ounces rise fast. Then gains level off. By 2–3 months, many babies take 4–5 oz per feed. By 4–6 months, many take 5–8 oz at each of 4–5 feeds, with milk still the main calorie source. Solid foods wait until the middle of the first year when ready signs appear. Milk stays the base through the first year.

What To Do If You’re Pumping

Pumped milk makes tracking intake simple. Label volumes and times. Early on, small bottles—1 to 3 oz—cut waste. As supply grows, store in 2–4 oz portions. When someone else feeds the baby, share the paced steps above so bottles aren’t finished on autopilot.

Signals That Merit A Call

Phone your pediatrician if any of these show up: fewer than expected wet diapers after the first days, deep yellow urine, dry mouth, a weak suck, fast breathing during feeds, repeated choking, or firm swelling under the tongue or jaw. A sharp drop in interest in every feed, or vomiting that shoots out forcefully, also needs a check.

Newborn Feeding: Quick Tips That Work

  • Feed on cue. Skin-to-skin helps cues show up sooner.
  • Hold baby upright and close. Watch the chin and cheeks for smooth, wide sucks.
  • Aim for a deep latch at the breast; pain is a sign to reposition.
  • Use paced bottle feeding and slow nipples.
  • Burp during and after feeds.
  • Keep night feeds dim and quiet to shorten wake time.
  • Track diapers and weight from week to week.
  • Be kind to yourself. Small tweaks pay off.
