Your toddler at 20 months

Still between the 18-month and 2-year checklists. The CDC's 2-year list includes pointing to things in a book when you ask and noticing when someone is hurt or upset.

There's no CDC checklist for 20 months; the CDC's checklists come at 18 months and 2 years. By 18 months, most children (75% or more) do things like “Looks at a few pages in a book with you”. Coming up by 2 years: “Points to things in a book when you ask, like ‘Where is the bear?’”. Both lists are below, with this month's play, talk and reading ideas.

Checked October 29, 2026.

Play today

Where's the bear?
In a picture book, ask "Where's the bear?" and wait for your toddler to point.
Lids off, lids on
Give your toddler a few plastic containers with easy lids to open and close.
A few stairs
Practice walking up a few stairs together, holding hands.
Safety: Always with you; use a gate when you're not there.

Things to say

“Where's the bear? You found it!”
“Lid off! What's inside?”
“Up, up, up.”

Say it, then wait. Give your toddler time to answer with a look, a sound or a word, and answer back.

A rhyme to share

Humpty Dumpty. Sit your toddler on your knees and let them "fall" gently between them, holding on.

The words are on Peabody's Nursery rhymes with lyrics list.

Talk to your pediatrician if…

Your toddler isn't doing the things on the CDC's 18-month list, has lost a skill they once had, or you're worried for any reason. Things on the 2-year 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.

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 2 years page. The CDC suggests filling in a milestone checklist and sharing it with your child's doctor; its Milestone Tracker app is free.
