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 9 months by completing a checklist with CDC’s free Milestone Tracker mobile app, using the Digital Online Checklist, or by printing the checklist.

Concerned About Your Child’s Development? Act Early.
You know your child best. Don’t wait. If your child is not meeting one or more milestones, has lost skills they once had, or you have other concerns, act early. Talk with your child’s doctor, share your concerns, and ask about developmental screening.
If you or the doctor are still concerned:
- Ask for a referral to a specialist who can evaluate your child more; and
- Call your state or territory’s early intervention program to find out if your child can get services to help. Learn more and find the number at cdc.gov/FindEI.
