Baby development, from birth to three
Choose your child’s age. Each stage explains what usually changes, how to play at that age and which signs are worth discussing with your paediatrician. Below it you will find the guide’s cards for every week or month.
This is general information about typical development, not medical advice. Every child develops at their own pace. If something worries you, talk to your paediatrician.
