Most three-week-olds nurse 8–12 times daily; wet diapers and steady weight gain show intake is enough.

Most newborns take 1–3 oz per feed in the first days, then 2–4 oz by about two weeks, with 8–12 feeds across 24 hours.

Most newborns take small, frequent feeds—often 8–12 times daily—then settle into a steadier rhythm as milk supply and swallowing skills grow.

Most parents do best by pumping the amount their baby drinks in the same time window, then tweaking based on wet diapers, weight gain, and comfort.

At two weeks, most babies take roughly 2–3 oz per feed across 8–12 feeds a day, and steady diapers plus weight gain are the clearest proof you’re making enough.

At 3 weeks postpartum, many babies take roughly 19–30 oz (560–900 mL) in 24 hours, so output looks different for nursing, pumping, or mixed feeding.

By one week, milk usually flows more steadily, and steady diaper output plus weight trend matter more than pumping totals.

Most 3-month-olds take 24–32 oz (710–950 mL) per day, split into 6–8 feeds, with steady weight gain and regular wet diapers.

Newborns tend to feed 8–12 times daily, starting with drops of colostrum and rising to roughly 60–90 ml per feed by 1 month.

Most 8-month-olds take about 20–28 oz (600–830 mL) of breastmilk in 24 hours, with solids changing the pattern more than the total.
