How Much Milk Does Your Baby Need? A 0–12 Month Guide, and Better Ways to Judge "Enough"

"Is my baby getting enough milk?" is probably the most asked — and most anxiety-inducing — newborn question. The principle first: ranges are references; your baby's cues and growth curve are the real answer.

Reference ranges by age (formula/bottle)

0–1 month: 60–90ml per feed, 8–12 feeds/day (on demand, including nights)
1–3 months: 90–150ml per feed, 6–8 feeds, ~600–900ml total
3–6 months: 150–210ml per feed, 5–6 feeds, ~700–1000ml total
6–9 months (with solids): ~600–800ml total as solids ramp up
9–12 months: ~500–600ml total; solids become a major nutrition source

Direct breastfeeding can't be measured — and doesn't need to be. Responsive feeding plus the signs below is enough.

Three signs more reliable than millilitres

Nappies: from day 5, six or more heavy wet nappies daily, pale urine
Growth curve: weight tracking steadily along baby's own centile (P15 vs P85 doesn't matter; crossing major lines downward does)
Demeanour: settled after feeds, alert and energetic when awake

If all three are good, intake is fine — even below the "reference range."

Common traps

Reading every cry as hunger: crying has ten causes; crying right after a feed is more likely gas or tiredness
Chasing the average: appetites vary by design; pushing extra millilitres mostly teaches feed refusal
Switching formula repeatedly: intake fluctuation is normal and formula-hopping rarely fixes anything the growth curve doesn't show
Cow's milk as the main drink before 12 months: it interferes with iron — the main drink stays breast milk or formula until one

When to get an assessment

Weight crossing down through two major centile lines, persistently low urine output, choking or laboured feeding, or vomiting with poor weight gain.

Ranges compiled from mainstream paediatric feeding guidance; premature or low-birth-weight babies need individualised plans.
