Newborns engage through eye contact, voices, touch, and simple back-and-forth moments from day one.

A newborn stomach holds about 5–7 mL on day one, rising to 22–27 mL by day three and 45–60 mL at one week.

Newborn size is flagged when birth weight tops 4,000–4,500 g, or when length or head size sits above the 97th percentile for age and sex.

Newborn poop doesn’t have a set size; soft stools that pass easily—often coin-sized by day 5—fit the norm in well-fed babies.

After day 4, a newborn poop should be at least coin-sized (≈2.5 cm across); more or bigger is fine if baby feeds and gains well.

Breast milk guards newborns with antibodies, prebiotics, and living cells that block germs and train early immunity.

To bottle-feed a newborn, hold them semi-upright, keep the nipple full of milk, follow hunger cues, pause to burp, and mix feeds safely.

In the first 2 weeks, newborns move from teaspoons on day 1 to 45–90 ml (1½–3 oz) per feed; 8–12 feeds daily with steady wet diapers.

Newborns usually take 45–90 ml (1.5–3 oz) per feed, adding up to roughly 300–900 ml (10–30 oz) in 24 hours.

A newborn stomach holds 5–7 mL on day 1, near 30 mL by day 3, and 45–60 mL by week 1.
