About this much formula in 24 hours
Based on AAP guidance of about 2.5 oz (75 mL) of formula per pound of body weight a day, up to 32 oz (about 950 mL). Follow your baby’s hunger and fullness cues rather than a fixed amount.
How much formula does my baby need?
The American Academy of Pediatrics (AAP) says that, on average, babies need about 2.5 ounces (75 mL) of formula a day for every pound (453 g) of body weight, up to a maximum of about 32 ounces (950 mL) a day. Most babies take 3 to 4 ounces per feed in the first month, increasing over time to around 7 to 8 ounces.
How often to feed
- First weeks: 8 to 12 feeds in 24 hours, at least every 3 hours
- 1 to 2 months: about every 3 to 4 hours
- 4 to 6 months: often 4 to 6 feeds a day
- 6 to 12 months: milk feeds decrease as solid foods increase
Follow your baby’s cues
Babies are good at regulating how much they need. Signs of hunger include rooting, sucking on hands and fussing. Signs of fullness include turning away, closing the mouth and slowing down. Never force your baby to finish a bottle.
Breastfed babies
Breastfed babies feed on demand, usually 8 to 12 times a day in the early weeks. It is not possible to measure intake directly, so wet nappies, dirty nappies and weight gain are the best guides. The AAP recommends a daily vitamin D supplement of 400 IU for breastfed babies.
Frequently asked questions
How do I know my baby is getting enough?
Steady weight gain, at least 6 wet nappies a day after the first week, and a baby who seems content after feeds are good signs.
Can I overfeed a formula-fed baby?
It can happen. Watch for fullness cues and avoid pushing your baby to finish the bottle.
When should I talk to a doctor?
If your baby has fewer wet nappies, is not gaining weight, vomits forcefully or seems unwell, contact your doctor.
