Most newborns need to eat every 2 to 3 hours - that's about 8 to 12 times in a day. This is true whether you're breastfeeding or bottle-feeding. The exact amount and timing will shift a little as your baby grows, but "often" is the normal answer for the first few weeks.
Note: This is general information, not medical advice. Your pediatrician can give you guidance specific to your baby.
How Much a Newborn Eats, Day by Day
A newborn's stomach is tiny - about the size of a small marble on day one. It grows fast.
| Age | Typical amount per feed |
|---|---|
| Day 1–2 | About ½ ounce (breast milk or formula) |
| End of week 1 | 1–2 ounces |
| Week 2 | 2–3 ounces |
These are averages. Breastfed babies in particular can vary a lot from feed to feed, and that's normal.
Breastfed vs. Formula-Fed: Why the Schedule Looks Different
Breast milk digests quickly, so breastfed newborns often want to eat every 2 to 3 hours, round the clock. Formula takes longer to digest, so formula-fed babies sometimes go a bit longer between feeds - closer to every 3 to 4 hours. Neither pattern is "better." They're just different, and both are normal.
Signs Your Baby Is Getting Enough
- Steady weight gain at checkups
- At least 6 wet diapers a day by about day 5
- Your baby seems content and relaxed after most feeds
- Regular, seedy or soft yellow stools (after the first week)
If you're worried your baby isn't feeding well - lots of crying at the breast or bottle, very few wet diapers, or no weight gain - call your pediatrician. Don't wait it out.
Cluster Feeding Is Normal Too
Some evenings, your baby may suddenly want to feed every hour or less for a few hours straight. This is called cluster feeding, and it's very common, especially in the early weeks and during growth spurts. It doesn't usually mean you don't have enough milk - it's just a phase, and it passes.
Frequently Asked Questions
How often should a newborn eat?
Most newborns eat every 2 to 3 hours, or about 8 to 12 times in 24 hours, whether breastfed or bottle-fed.
Do formula-fed babies eat less often than breastfed babies?
Often yes, slightly - formula digests more slowly, so formula-fed newborns sometimes go closer to every 3 to 4 hours between feeds.
What is cluster feeding?
It's when a baby wants to feed much more often than usual for a few hours, often in the evening. It's common and doesn't usually mean low milk supply.
