Daily How Much

Most 3-week-olds take 2–3 oz per feed, 8–12 feeds daily; wet diapers and steady weight gain show it’s enough.

Most 1-month-olds take about 570–900 mL (19–30 oz) of milk in 24 hours, split across frequent feeds that match hunger cues.

By 4–6 weeks, many parents make about 25–35 oz (750–1,050 mL) a day, with wide normal variation.

Most 2-week-olds take 60–90 mL per feed, 8–12 feeds in 24 hours, with plenty of wet diapers and rising weight.

Most pumpers collect 19–30 oz (560–900 mL) per day once milk is established, split across sessions.

Many 1-month-olds take 2–4 oz per feed, 8–12 feeds in 24 hours, with steady weight gain and plenty of wet nappies.

Most 2-month-olds take 24–32 oz (710–950 mL) a day, split into 6–8 feeds, with diapers and weight gain as checks.

Most day-4 newborns take about 30–60 mL (1–2 oz) per feed across 8–12 feeds in 24 hours.

Most newborns nurse 8–12 times in 24 hours, and diaper output plus steady weight gain show they’re taking in enough milk.

Most fully breastfed babies take in around 19–30 oz (570–900 mL) in 24 hours once milk is in.
