Developmental Milestones Matter!

Download CDC’s new Milestone Tracker app for a fun and easy way to track and celebrate your child’s developmental milestones!

Skills, such as taking a first step, smiling for the first time, and waving “bye-bye,” are called developmental milestones. From birth to 5 years, your child should reach milestones in how he or she plays, learns, speaks, acts and moves. Parents and caregivers can use CDC’s “Learn the Signs. Act Early.” tools to track developmental milestones from as early as 2 months to help better understand children’s abilities and stay in tune with their developmental health.
