Developmental Milestones

Developmental milestones are the things most children can do by a certain age. While all children develop differently, it helps to know if your child is meeting typical milestones and how you can support their healthy development. How your child plays, learns, speaks, acts and moves offers important clues about your child’s development. Below is information to help you understand what’s happening at different stages of your child’s life and how you can help them learn and grow.
