For the newborn hepatitis B vaccine in the USA, the standard volume is 0.5 mL of a single-antigen HepB shot given intramuscularly at birth.

Most newborns nurse about 10–20 minutes per breast; watch feeding cues and steady swallowing rather than the clock.

At one week, most newborns take 45–90 ml per feed, about 8–12 times daily; steady weight gain and wet diapers confirm enough milk.

Most newborns take about 45–90 mL per feed in the first weeks, adding up to roughly 8–12 feeds a day, with daily intake trending toward ~150 mL/kg.

By week 2–4, newborns drink around 570–900 mL a day; for formula, use ~75 mL per lb (max 960 mL in 24 hours).

Most full-term newborns drink about 150–200 ml per kg of body weight in 24 hours after the first week, with smaller, frequent feeds in the first days.

In the first weeks, most newborns take 30–90 ml per feed, rising to 60–120 ml by 2–4 weeks, with cues and weight guiding exact amounts.

On day 1, offer 5–7 mL per feed; by week 1, 45–60 mL; by week 4, 75–120 mL, with daily intake near 150 mL/kg split across 8–12 feeds.

Most newborns start with tiny 2–10 mL feeds, then reach about 60–120 mL per feed by 2–4 weeks, spread across 8–12 meals a day.

Most newborns take tiny feeds at first—then about 150–200 ml per kg per day by the end of week one, spread across 8–12 feeds.
