Formula only? The formula feeding calculator gives per-bottle formula amounts. Want the math by weight? See the baby milk intake by weight chart.
Newborns (0–2 months) typically need 150–180 ml of milk per kg of body weight per day. A 3.5 kg (7.7 lb) newborn would need roughly 525–630 ml (18–21 oz) daily across 8–12 feedings. The calculator gives you a personalized range based on your baby's exact weight.
Weigh your baby, pick the ml/kg/day for their age (0–2mo: 150–180 · 2–6mo: 120–150 · 6–12mo: 100–120), multiply weight by the rate, then divide by daily feedings for the per-bottle amount. The form above does the math instantly.
A 3-month-old usually takes 4–6 oz (120–180 ml) per feeding, with 5–6 feedings a day — about 24–32 oz (700–950 ml) total. Heavier babies sit at the top of that range. Enter your baby's weight above for a tailored number.
Yes. Choose Pumped milk + formula and enter the measured pumped milk already offered to see a formula top-up range. Direct nursing cannot be measured precisely at home, so that mode does not guess a remainder; use a supplement amount from your pediatrician or lactation specialist when you have an individual plan.
Newborns: 8–12 feeds a day (every 2–3 hours). 2–3 months: usually 6–8. By 6 months: 5–6. Always read your baby's cues over the clock, and check in with your pediatrician for anything that feels off.
Treat the result as a range, not a quota. Six or more wet diapers a day, steady weight gain, and a content baby after feeds are stronger signals than hitting an exact ml number.
Recalculate with a current measured weight and follow hunger and fullness cues. If weight gain slows or your baby falls away from their usual growth pattern, do not calculate from a goal weight or concentrate formula yourself—ask your pediatrician to assess feeding and growth first.
Use it only as a rough orientation. Preemies often need fortified milk and individualized volumes. Your neonatologist or pediatrician should set the actual targets.
