How your child plays, learns, speaks, acts, and moves offers important clues about your child’s development. Developmental milestones are things most children (75% or more) can do by a certain age. Check the milestones your child has reached by the end of 15 months by completing the checklist below. Share it with your child’s doctor, teacher, and other providers, and be sure to talk about the milestones your child has reached and what to expect next.
Checking children’s development regularly is important. CDC’s free Milestone Tracker app is also available to complete the checklists, with reminders and helpful tips on the go! Available on the AppStoreexternal icon and GooglePlayexternal icon.

What Most Babies Do by this Age:
Selected “not sure”? Watch for these milestones over the next week or two. Try some things with your child that gives him/her the chance to show the milestone. If you’re still not seeing the milestone, see the steps below.
Selected “not yet” or have other concerns or questions about your child’s development? Talk with your child’s doctor, teacher and/or another trusted provider. Share the checklist and any questions or concerns you might have. Ask about developmental screening. It’s recommended for all children. If you, the doctor, teacher, or other provider is still concerned after screening, ask to be connected with (1) a specialist who can learn more about your child AND (2) with services and other supports that may help.
