How much formula does a baby need?
The AAP's HealthyChildren.org says a newborn takes no more than about 1 to 2 ounces a feeding in the first week, growing to 3 to 4 ounces by 1 month and 6 to 8 ounces, 4 or 5 times in 24 hours, by 6 months. Most babies should not average more than about 32 ounces a day. Follow your baby's cues.

Formula amounts by age
| Age | Amount per feeding | How often |
|---|---|---|
| First week | No more than about 1 to 2 ounces (30 to 60 mL) | On your baby's cues |
| 1 month | Grows to 3 to 4 ounces (90 to 120 mL) | About every 3 to 4 hours |
| 2 and 4 months | The AAP page gives no amount | Most babies no longer need middle-of-the-night feedings; daytime gaps may stretch to 4 to 5 hours |
| 6 months | 6 to 8 ounces (180 to 240 mL) | 4 or 5 feedings in 24 hours |
Over a whole day
The AAP says babies average about 2½ ounces (75 mL) of formula per pound of body weight per day, and most should not average more than about 32 ounces (960 mL) in 24 hours. Talk with your pediatrician if your baby is regularly above or below this.
Hunger and fullness
The AAP says a baby who becomes fidgety or easily distracted during a feeding is likely finished. A baby who empties the bottle but keeps smacking their lips may still be hungry.
After 6 months
The CDC says breast milk or infant formula stays the main source of nutrition from 6 to 12 months, while solid foods slowly make up more of the diet. See starting solids, and water for the first year.
