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 30 months (from the CDC)

  • Encourage "free play," where your child can follow her interests, try new things, and use things in new ways.
  • Use positive words and give more attention to behaviors you want to see ("wanted behaviors"), than to those you don't want to see. For example, say "I like how you gave Jordan the toy."
  • Give your child food choices that are simple and healthy. Let him choose what to eat for a snack or what to wear. Limit choices to two or three.
