If something worries you

You know your child best. If your child isn't reaching one or more milestones, has lost skills they once had, or you have other concerns, talk with your child's doctor. The CDC says not to wait. You can also contact your state's early intervention program at cdc.gov/FindEI.

Things to try at 4 years (from the CDC)

  • Help your child be ready for new places and meeting new people. For example, you can read stories or role play (pretend play) to help him be comfortable.
  • Read with your child. Ask him what's happening in the story and what he thinks might happen next.
  • Help your child learn about colors, shapes, and sizes. For example, ask the color, shapes, and size of things she sees during the day.
