Getting to know your child’s milestones is as simple as playing with your child.

Skills such as taking a first step, smiling for the first time, and waving “hi” are called developmental milestones. As children grow, they reach milestones in how they play, learn, speak, act, and move. While all children grow and change at their own rate, experts on child development target a window of time when a child may reach each milestone.
