Common questions
Asked a lot.
Eight things parents type into Google at 2 a.m., answered without filler.
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.
