How to use these numbers

Every figure here is quoted from the organisation named under it. Where a source gives no number for an age, the row is simply missing — we leave the gap rather than fill it with a guess, and we never average between two ages.

These are typical ranges, not targets. Babies vary from day to day. If you are worried about how much your baby eats, sleeps or wets, ask your paediatrician.
