How Much Should a Newborn Eat?
In the first days a newborn takes about 1 to 2 teaspoons of colostrum per feed, growing to roughly 1 to 2 ounces per feed by the end of the first week. By one month most babies take about 3 to 4 ounces every three to four hours, and by three months about 4 to 6 ounces every four hours. Breastfed newborns typically feed 8 to 12 times in 24 hours; formula-fed babies feed less often because formula digests more slowly.
Feeding amounts by age
| Age | Amount per feed | Feeds per 24 hours | Daily total |
|---|---|---|---|
| Day 1 | 1 to 2 tsp (5 to 10 ml) | 8 to 12 | About 1 to 2 oz |
| Days 2 to 3 | 0.5 to 1 oz (15 to 30 ml) | 8 to 12 | About 6 to 10 oz |
| Days 4 to 7 | 1 to 2 oz (30 to 60 ml) | 8 to 12 | About 14 to 20 oz |
| 2 weeks to 1 month | 2 to 4 oz (60 to 120 ml) | 7 to 10 | About 20 to 26 oz |
| 1 to 2 months | 3 to 4 oz (90 to 120 ml) | 6 to 8 | About 24 to 30 oz |
| 3 months | 4 to 6 oz (120 to 180 ml) | 5 to 7 | About 25 to 32 oz |
These are typical ranges, not targets. Healthy babies vary, and your pediatrician's guidance for your baby always comes first.
Breastfeeding: how much is hard to measure, so watch other signs
At the breast you cannot see ounces, so intake is judged by output and growth instead. Expect 8 to 12 feeds in 24 hours in the newborn weeks, active swallowing during feeds, and breasts that feel softer afterward. Do not restrict or stretch feeds to hit a schedule in the early weeks. See how to know if your baby is getting enough milk for the full checklist.
Formula: a rough daily rule
A common guideline is about 2.5 ounces of formula per pound of body weight per day, up to roughly 32 ounces daily. A 9 pound baby lands near 22 ounces a day. Split across seven feeds, that is about 3 ounces per feed. Follow your baby's hunger and fullness cues rather than pushing a bottle to finish.
Pumped milk: amounts do not scale up the way formula does
Breast milk intake stays fairly flat from about one month to six months, averaging 25 to 30 ounces per day. If you are building bottles of pumped milk, roughly 3 to 4 ounces per feed covers most babies in that window. A baby who takes a big bottle is often responding to fast flow, not extra hunger.
Hunger and fullness cues
- Early hunger: stirring, rooting, hands to mouth, lip smacking
- Late hunger: crying. Calm your baby first, then feed
- Full: slowing or stopping sucking, releasing the nipple, relaxed hands, turning away
When to call your provider
- Fewer than six wet diapers a day after day five
- Birth weight not regained by about two weeks
- A baby too sleepy to wake for feeds, or who consistently feeds fewer than eight times a day in the newborn weeks
- Persistent vomiting, or feeding that is always distressed
