Baby Development at 0 to 1 Month

This is not a month for strict schedules. Pregnancy Birth and Baby says newborns often do not follow schedules in the first couple of months, and a feed, play, sleep rhythm is more useful than a clock-based routine. Expect every day to look slightly different while feeding and sleep settle.

Feeding takes up a lot of the first month. Newborns commonly need 8 to 14 feeds or more in 24 hours, including overnight feeds. Breastfeeding, bottle-feeding, expressing, and mixed feeding can all be normal family plans, but poor feeding, fewer wet nappies, ongoing vomiting, unusual sleepiness, or weight worries need advice from a midwife, child and family health nurse, GP, or hospital.

Sleep is also uneven. Many newborns sleep up to 14 to 17 hours in 24 hours, but usually in short stretches of about 2 to 4 hours, and they do not yet know night from day. Keep the setup safe every time: baby on their back, head and face uncovered, in their own safe sleep space, and near a caregiver as recommended by your local safe-sleep guidance.

At around 0 to 1 month, babies are often fascinated by faces. They may be able to follow your face briefly with their eyes and see you best when you are close, around 20 cm away. High-contrast patterns, simple books, and face-to-face time can be interesting, but your baby may look away when they need a break.

Your baby can hear you and may already know your voice. Sudden sounds can still startle them. Talking, singing, reading, humming, or narrating a nappy change all count as useful language exposure, even when your baby cannot answer with words.

Crying is communication in this stage. Your newborn may cry because they are hungry, tired, uncomfortable, overstimulated, cold, hot, or simply need holding. Responding with feeds, cuddles, a nappy change, gentle rocking, or a quieter room helps your baby feel safe; you cannot spoil a newborn by comforting them.

Skin-to-skin contact can support bonding and settling for both baby and caregiver. Pregnancy Birth and Baby frames the fourth trimester as a period of adjustment after birth, when swaddling, skin-to-skin, feeding, safe bathing, and gentle movement can help newborns feel secure. Follow safe wrapping guidance and stop or change wrapping when it no longer suits your baby or safe-sleep advice.

Nappies are one of the best first-month clues. In the first week, poo changes from black and sticky meconium toward lighter colours, and wet nappies help show whether feeding is going well. Ask for advice if nappies are much fewer than expected, poo or wee worries you, there is blood, or your baby seems unwell.

Umbilical cord care is usually simple. Keep the stump clean and dry, wash around it with clean water only if it gets dirty, and pat it dry. Seek advice if the area becomes red, swollen, smelly, leaking pus, bleeding more than a small spot, or if your baby has a fever or seems unwell.

Health checks begin immediately. Your baby is usually checked at birth, then again in the first 1 to 4 weeks, with later checks around 6 to 8 weeks, 6 months, and 12 months. These appointments track development, weight, length or height, and head circumference, and they are the right place to ask small questions before they become stressful.

Newborn screening is part of the early health routine. In Australia, babies are offered hearing screening and newborn bloodspot screening, often around 48 to 72 hours after birth. You may also be offered vitamin K and the first hepatitis B vaccination while in hospital, with the next vaccine round due around 2 months of age.

Your baby's personal health record matters. Bring it to appointments, use it to record growth and immunisations, and write questions in it when you are too tired to remember them. It can also help different providers understand what has already been checked.
