Baby month by month

Milestones, average growth, feeding, sleep and a simple checklist for every month from birth to 2 years.

First year: months 1 to 12

From newborn reflexes to first steps: fast growth, first foods and big changes in sleep.

Second year: months 13 to 24

Walking, talking and growing independence, with toddler meals and one nap a day.

Milestones on these pages follow the CDC’s 2022 developmental milestone checklists. Every child develops at their own pace. If you are worried about your child’s development, talk to your doctor or health visitor.
