Your baby's first year (0–12 months)
Understand early milestones, feeding, safe sleep and caring for your baby during the first year.
The first year: birth to 12 months
CDC publishes milestone checklists for ages 2, 4, 6, 9 and 12 months. Every baby develops differently; discuss concerns or any loss of skills with their clinician.
Birth–1 month · Settling in
Pay attention to feeding, wet nappies, sleep and newborn checkups. Seek medical advice if your baby feeds poorly or appears unwell.
2 months · Connecting
Many babies smile in response to being spoken to and look at their caregiver's face.
4 months · Growing stronger
Many babies hold their head steadier when supported and make sounds to interact.
6 months · Exploring
Many babies laugh, reach for objects and explore with hands and mouth.
9 months · Familiar faces
Many babies respond to their name and show feelings when a familiar caregiver leaves.
12 months · Taking initiative
Many babies wave, play simple games and pull up to stand. Not all babies walk by 12 months.
Three essentials for the first year
Safe sleep
Put your baby on their back for every sleep on a firm, flat surface. Keep pillows, loose blankets and toys out of the sleep space. Room-share without sharing the same sleep surface when possible.
Milk and introducing food
WHO recommends exclusive breastfeeding for about the first six months when possible, with suitable support. From around six months, introduce safe, suitable complementary foods while continuing milk feeds. Ask your care team about your baby's needs.
Checkups and immunizations
Follow local child-health and vaccination visits to review growth, development and health. A milestone list cannot replace professional screening.
