Newborn Development: The First Month

Most newborns lose a small amount of weight in the first few days (usually 5-10% of birth weight) before regaining it by around 2 weeks. By the end of the first month, babies typically gain back to or slightly above their birth weight.

Your baby's head will seem large in proportion to their body — this is completely normal. The soft spots (fontanelles) on the skull allow room for rapid brain growth and will close gradually over the first couple of years.

Newborns sleep a lot — typically 14 to 17 hours a day, but in short stretches of 2 to 4 hours at a time, since their tiny stomachs need frequent feeding. There's no real day-night rhythm yet; that develops over the coming weeks and months.

Always place your baby on their back to sleep, on a firm, flat surface, with no loose blankets, pillows, or soft toys in the crib, to reduce the risk of SIDS.

Newborns typically feed every 2 to 3 hours, whether breastfeeding or formula feeding — that's 8 to 12 feeds in a 24-hour period. Watch for hunger cues like rooting, sucking on hands, or fussiness rather than waiting for crying, which is a later sign of hunger.

If breastfeeding, your milk will transition from colostrum to mature milk over the first week or so. If you have concerns about latch, supply, or feeding patterns, a lactation consultant can be a valuable resource.

At this stage, your baby's main activities are eating, sleeping, and gradually becoming more alert. Short bursts of tummy time while awake (a minute or two, several times a day) help build neck and shoulder strength.

Talking, singing, and making eye contact during feeds and diaper changes all support early bonding and brain development, even though your baby can't respond yet.

Keep the umbilical cord stump clean and dry until it falls off on its own, usually within 1 to 2 weeks. Avoid submerging your baby in water (sponge baths only) until the stump has fallen off.

Watch for jaundice (yellowing of skin or eyes), which is common in newborns but should be monitored by your pediatrician, especially if it seems to worsen.

Several vaccines are given at birth, typically before you leave the hospital: BCG (protects against tuberculosis), the first dose of Hepatitis B, and OPV (oral polio vaccine). Your pediatrician or hospital staff will guide you through this schedule.
