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.

Missing Milestones?  Time to Act Early

Talk with Your
Child’s Doctor

These are the results of your examination

Talk with your child’s doctor at every visit about the milestones your child has reached and what to expect next.

Making sure all children have the help and support they need to overcome challenges, find their strengths, and reach their full potential starts early. You know your child best. If your child is missing milestones for his or her age or you have concerns about your child’s development,

If you or the doctor is still concerned,

  • Ask the doctor for a referral to a specialist; and
  • Call for a free evaluation to find out if your child can get services to help.

Don’t wait. Acting early can make a real difference!
