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. The intake volumes apply to both formula and expressed breast milk. Breastfed babies often feed a little more frequently with slightly smaller per-feed volumes, but the daily totals overlap.
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 every 2–4 weeks. If your baby drains bottles fast, wakes more at night, or weight gain slows on the growth chart, bump the daily total and reassess.
Use it only as a rough orientation. Preemies often need fortified milk and individualized volumes. Your neonatologist or pediatrician should set the actual targets.
