Baby Feeding Amount Calculator
See how much formula is typical for your baby's age and weight — daily totals, a rough amount per bottle, and how many feeds a day to expect. These are gentle ranges for bottle and formula feeds; breastfed babies feed to their own cues.

- Optionally add their weight to estimate bottle sizes.
- See typical feeds per day, the gap between feeds, and per-bottle and daily formula amounts.

Common questions
How much formula should my baby drink?
A common guide for formula-fed infants is about 150 ml per kilogram of body weight per day (roughly 2.5 oz per pound), usually capped around 960 ml (32 oz) a day. Spread that across the day's feeds. Always follow your baby's hunger and fullness cues over a fixed number.
How much should a breastfed baby eat?
Breastfed babies regulate their own intake, so there's no bottle number to hit. Feed responsively — on demand, watching for hunger cues and swallowing — typically 8–12 times a day in the early weeks.
How many ounces is that?
The calculator shows both millilitres and ounces (1 oz ≈ 29.6 ml). Bottle markings vary, so measure with the bottle or scoop instructions for your formula.
When do amounts change with solids?
From around six months, solids gradually complement milk, but milk stays the main source of nutrition through the first year. Daily milk often eases down as solids increase.
