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 1 year (from the CDC)

  • Teach your baby "wanted behaviors." Show her what to do and use positive words or give her hugs and kisses when she does it. For example, if she pulls your pet's tail, teach her how to pet gently and give her a hug when she does it.
  • Talk or sing to your baby about what you're doing. For example, "Mommy is washing your hands" or sing, "This is the way we wash our hands."
  • Build on what your baby tries to say. If he says "ta," say "Yes, a truck," or if he says "truck," say "Yes, that's a big, blue truck."
