From day 1 to week 2, per-feed intake rises from 5–15 ml to about 30–90 ml, and most newborns feed 8–12 times in 24 hours.

In the first week, most newborns take ~5–60 mL per feed, rising to 60–90 mL by days 4–7 (about 150 mL/kg/day across 24 hours).

Most newborns need one more layer than you in the same setting, with hats outdoors only and sleepwear chosen for room temperature and safe sleep.

For a term baby, a healthy birth weight usually sits between 2.5–4.0 kg; under 2.5 kg is classed as low birth weight by WHO.

Most newborns use 8–12 disposable diapers daily in weeks 1–4; at least 6 wet diapers by day 5 signal good intake.

Newborn breastfeeding hours: expect 8–12 feeds in 24 hours (about every 2–3 hours), with one 4–5-hour stretch once weight and output are steady.

Most families do well with 6–8 newborn bottles plus 8–12 slow-flow nipples; that covers daily feeds while extras dry, sterilize, or go to daycare.

Newborn feeding intervals: aim for 2–3 hours by day and up to 3–4 hours at night in the first weeks, with 8–12 feeds across 24 hours.

Newborn sleep: most babies get 14–17 hours per day in 2–4 hour stretches; totals from 11–19 hours can still be normal.

Most newborns gain about 1 inch (2.5 cm) in length each month during the first 6 months, then about 0.5 inch (1.3 cm) monthly from 7–12 months.
