How your child plays, learns, speaks, acts, and moves offers important clues about your child’s development. Developmental milestones are things most children (75% or more) can do by a certain age. Check the milestones your child has reached by the end of 1 year by completing the checklist below. Share it with your child’s doctor, teacher, and other providers, and be sure to talk about the milestones your child has reached and what to expect next.

If your child was born more than 3 weeks prematurely, use his/her corrected ageexternal iconexternal icon. If your child’s age falls between 2 checklist ages, use the checklist for the younger age.

Checking children’s development regularly is important. CDC’s free Milestone Tracker app is also available to complete the checklists, with reminders and helpful tips on the go!  Available on the AppStoreexternal icon and GooglePlayexternal icon.

*These fields are required.


CDC does not collect or share any personal information that can be used to identify you or your child.

What Most Babies Do by this Age:

Social/Emotional

Plays games with you, like pat-a-cake




Language/Communication

Waves “bye-bye”




Calls a parent “mama” or “dada” or another special name




Understands “no” (pauses briefly or stops when you say it)




Cognitive (learning, thinking, problem-solving)

Puts something in a container, like a block in a cup




Looks for things he sees you hide, like a toy under a blanket




Movement/Physical Development

Pulls up to stand




Walks, holding on to furniture




Drinks from a cup without a lid, as you hold it




Picks things up between thumb and pointer finger, like small bits of food




Selected “not sure”? Watch for these milestones over the next week or two. Try some things with your child that gives him/her the chance to show the milestone. If you’re still not seeing the milestone, see the steps below.

Selected “not yet” or have other concerns or questions about your child’s development? Talk with your child’s doctor, teacher and/or another trusted provider. Share the checklist and any questions or concerns you might have. Ask about developmental screening. It’s recommended for all children. If you, the doctor, teacher, or other provider is still concerned after screening, ask to be connected with (1) a specialist who can learn more about your child AND (2) with services and other supports that may help. Visit www.cdc.gov/Concerned for more information.


– Share the checklist with your child’s healthcare provider, early educator, WIC Clinic, or other care providers by FORWARDING the email you receive.
– Be sure to add your child’s name and birthdate (if needed) when forwarding the checklist so your provider can identify it as your child’s.
