How babies develop


A brief guide

All babies develop at different rates - and if they are not doing the same things as someone else's baby of the same age, it doesn't mean they have learning or development problems.

Below is a general guide to the ages at which you can expect babies to reach certain milestones. But don't worry if your baby hasn't done so.
