Your toddler at 17 months

Still between the 15-month and 18-month checklists. The CDC's 18-month list includes looking at a few pages in a book with you and helping you dress by pushing an arm through a sleeve.

There's no CDC checklist for 17 months; the CDC's checklists come at 15 months and 18 months. By 15 months, most children (75% or more) do things like “Shows you affection (hugs, cuddles, or kisses you)”. Coming up by 18 months: “Helps you dress him by pushing arm through sleeve or lifting up foot”. Both lists are below, with this month's play, talk and reading ideas.

Checked October 29, 2026.

Talk to your pediatrician if…

Your toddler isn't doing the things on the CDC's 15-month list, has lost a skill they once had, or you're worried for any reason. Things on the 18-month list are still coming.

You know your child best. Don't wait. If your child is not meeting one or more milestones, has lost skills he or she once had, or you have other concerns, act early. Talk with your child's doctor, share your concerns, and ask about developmental screening.
CDC, Learn the Signs. Act Early.

If you or the doctor are still concerned, the CDC says to ask for a referral to a specialist, and to call your state's early intervention program (find the number on the CDC's list). You do not need to wait for a doctor's referral or a medical diagnosis to make this call. If your child is younger than 3 years old, contact your local early intervention system.

More from the CDC: Concerned about your child's development? If your child seems unwell, call your pediatrician, or 911 in an emergency.

What the CDC suggests you share with the doctor

What are some things you and your child do together?
What are some things your child likes to do?
Is there anything your child does or does not do that concerns you?
Has your child lost any skills he/she once had?
Does your child have any special healthcare needs or was he/she born prematurely?

From the CDC's Milestones by 18 months page. The CDC suggests filling in a milestone checklist and sharing it with your child's doctor; its Milestone Tracker app is free.
