When to talk to your pediatrician

Call your pediatrician today
  • Your child can’t do one or more of these by 3 years
  • Loses skills they once had, at any age
  • Doesn’t respond to sounds or their name
  • Doesn’t make eye contact or smile back by 6 months
  • You have a feeling something isn’t right. Trust it and ask.

General guidance based on AAP, NHS and CDC advice, not a diagnosis. If your gut says something is wrong, call your pediatrician or nurse line. You never need permission to seek care.

Questions parents ask

What should a 3-year-old be doing?
By 3 years, most children (75% or more, per the CDC): calms down within 10 minutes after you leave them, like at childcare drop-off; talks with you in conversation using at least two back-and-forth exchanges; strings items together, like large beads or macaroni.
What if my child isn't doing all of these at 3 years?
Tell your pediatrician at the next checkup, or call sooner if you are worried. Each item is something most children do by this age, so a missing one is worth discussing but is not a diagnosis. In the US, you can also contact Early Intervention (under 3) or your school district (3+) directly for a free evaluation.
