Most newborns double birth weight around 4–6 months, with many reaching it near 4–5 months when feeding and growth stay on track.

Most newborns need 150–200 mL per kg each day across 8–12 feeds; in week 1, per-feed volumes rise from 5–7 mL to 45–60 mL.

Newborn intake typically starts at 5–30 mL per feed on day one and rises to 45–90 mL every 2–3 hours by week one—about 300–600 mL a day.

Most newborns take about 150–180 mL per kg in 24 hours from all feeds, split across frequent feedings; watch diapers and weight to confirm intake.

Newborn feeds start near 2–10 mL on day 1, rise to 30–60 mL by days 3–4, and from weeks 2–6 many take 60–90 mL per feed across 8–12 feeds daily.

In the first 4 days, newborn feeds often rise from 2–10 mL to 5–15 mL, 15–30 mL, and 30–60 mL per feed, with about 8–12 feeds in 24 hours.

Most newborns start at 5–7 mL on day 1, rise to 30–60 mL by days 2–3, and reach about 30–60 mL per feed during the first week, with 8–12 feeds

In the first week, newborn milk intake ranges from about 5–7 ml per feed on day 1 to 30–60 ml by days 3–7, spread across 8–12 feeds each day.

Newborn breast milk amounts start tiny: roughly 2–10 mL per feed on day 1, rising toward 30–60 mL by day 4 and about 45–60 mL by day 7.

For expressed breast milk for newborns, aim 5–15 mL per feed on days 1–2, moving toward 60–90 mL by day 5; match amounts to hunger cues.
