Most newborns take 1–2 oz every 2–3 hours at first, then 2–3 oz; about 2.5 oz per pound per day, not above ~32 oz in 24 hours.
Newborn Formula Intake: How Much And How Often?
Your baby’s stomach is tiny and grows fast. In the first few days, offer small, frequent bottles. Expect feeds every 2–3 hours around the clock. By the end of the first month, many babies settle into 3–4 oz per feed with longer gaps between bottles. Total volume across a day usually lines up with body weight.
Two trusted rules of thumb guide the early weeks. First, start with 1–2 oz per feeding in the first days and watch for hunger cues. Second, aim for roughly 2.5 oz of formula per pound of body weight per 24 hours, with a practical ceiling near 32 oz a day. Your baby may take a little more or less at any single feeding, and that’s normal.
Feeding Snapshot For The First 4 Weeks
| Age | Typical Amount Per Feed | Feeds In 24 Hours |
|---|---|---|
| Days 0–7 | 1–2 oz (30–60 mL) | 8–12 (about every 2–3 hours) |
| Weeks 2–3 | 2–3 oz (60–90 mL) | 7–9 (about every 3 hours) |
| Week 4 | 3–4 oz (90–120 mL) | 6–8 (about every 3–4 hours) |
Use this as a flexible map, not a strict script. If bottles disappear fast and your newborn still roots or licks lips, offer a bit more. If your baby turns away or relaxes their hands, they’re likely done. You never need to push a bottle to “empty.”

Reading Hunger Cues And Fullness Cues
Crying is late. Catch the earlier signs. Newborns put hands to mouth, pucker or smack lips, and turn toward the bottle. Those are green lights to feed. As a feeding wraps up, you’ll see a closed mouth, turning away, and loose, relaxed hands. That’s your signal to pause or stop.
Responsive feeding keeps intake on target. Offer when early cues show, pause for burps, and end when your baby shows fullness. This pattern helps avoid overfilling and keeps bottles pleasant.
Close Variation: How Often Should A Newborn Drink Formula?
Through the first week, think “little and often.” Plan on 8–12 feeds in 24 hours, then ease toward every 3–4 hours by the end of the first month. Some babies like two smaller bottles close together during a lively window, then a longer stretch of sleep. Others spread feeds evenly. Both patterns can work if daily totals and growth look good.
Night feeds are part of the picture. Expect two or more overnight bottles early on. As stomach capacity grows and daytime intake rises, many babies naturally lengthen night sleep. There’s no race here. Follow your baby’s rhythm while staying within safe ranges for volume.
Daily Totals Using The 2.5 Oz Per Pound Rule
A handy way to estimate a day’s needs is the body-weight rule. Multiply your newborn’s weight in pounds by 2.5 to get an approximate daily total in ounces. Then split that across feeds. Stay under about 32 oz a day unless your pediatrician gives different advice.
Examples By Weight (Approximate Daily Total)
| Baby’s Weight | Daily Formula | Example Split Across Feeds |
|---|---|---|
| 6 lb (2.7 kg) | ~15 oz / day | 8 feeds of ~2 oz |
| 8 lb (3.6 kg) | ~20 oz / day | 8 feeds of ~2.5 oz |
| 10 lb (4.5 kg) | ~25 oz / day | 7 feeds of ~3.5 oz |
These are starting points. Some days your baby will want more at one feeding and less at the next. Watch cues and the big picture across 24 hours. Growth, diapers, and contented wake time matter more than any single bottle size.
How Often Should You Wake A Sleepy Newborn?
During the first few weeks, don’t let long stretches shave off needed calories. If sleep runs past 3–4 hours, wake your baby and offer a bottle. Once weight gain is steady and your clinician is happy with growth, you can stretch intervals as your baby allows.
Bottle Size, Nipple Flow, And Pace
Use small bottles at first. A slow-flow nipple helps your baby control the stream. Hold the bottle so milk fills the nipple and air stays at the top. Offer short pauses to burp. Paced bottle feeding—tilting the bottle down now and then—lets your baby breathe, rest, and decide when to stop. That supports self-regulation and reduces spit-up linked to fast flow.
If bottles finish in minutes with gulping and coughing, try a slower nipple. If your baby works hard, gets frustrated, and takes ages to finish, the nipple may be too slow. Tuning flow is a small tweak that can make feeds smoother.
Mixing And Serving Formula Safely
Clean your hands and the workspace. Wash and air-dry bottles and nipples. Add the correct amount of safe water to the bottle first, then the measured powder. Shake until fully blended. Wrong ratios can be risky, so stick to the label’s scoop and water amounts.
Use prepared formula within 2 hours, or refrigerate right away and use within 24 hours. Once a feeding starts, finish within an hour and toss leftovers. Never warm bottles in a microwave; warm under running warm water or in a container of warm water and test drops on your wrist.
For babies under 2 months, preterm infants, or infants with weak immunity, take extra care to reduce Cronobacter risk. Use very hot water for mixing powdered formula, then cool before feeding. Ready-to-feed formula is another option during this window.
Burping, Spit-Up, And Overfeeding
Short pauses help. Burp mid-feed and at the end. Keep your baby fairly upright during and after bottles. Spit-up is common; watch comfort and weight gain, not laundry. If spit-up surges with fussing or arching, check bottle flow and take more breaks. Smaller, more frequent feeds can help.
Overfilling can show up as frequent spit-up, gassiness, or a baby who seems uncomfortable after bottles. Follow fullness cues, and don’t feel the need to finish every ounce poured. If sucking needs are strong after a full feed, offer a pacifier.
Diapers, Growth, And When To Call Your Pediatrician
Plenty of wet diapers, steady weight gain, and bright awake periods are reassuring signs. Reach out for advice if your newborn is taking far less than expected for age, shows weak suck, has very few wet diapers after the first week, seems unusually sleepy during feeds, or is vomiting forcefully. Ask about feeding plans for preterm babies, jaundice, reflux, or any medical condition.
Your Easy Feeding Checklist
1) Offer 1–2 oz every 2–3 hours in the first days. 2) By week 4, many babies take 3–4 oz every 3–4 hours. 3) Estimate daily needs with 2.5 oz per pound, staying near or below 32 oz a day. 4) Watch hunger and fullness cues. 5) Wake for feeds in the early weeks. 6) Mix and store formula safely. 7) Call your pediatrician with any concerns.
