Important Milestones: Your Child By Two Years

CDC’s milestones and parent tips have been updated and new checklist ages have been added (15 and 30 months). Due to COVID-19, updated photos and videos have been delayed but will be added back to this page in the future. For more information about the recent updates to CDC’s developmental milestones, please review the Pediatrics journal article and these important key points.

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 2 years by completing a checklist with CDC’s free Milestone Tracker mobile app, for iOS and Android devices, using the Digital Online Checklist, or by printing the checklist [1 MB, 2 Pages, Print Only] below.

“Learn the Signs. Act Early.” materials are not a substitute for standardized, validated developmental screening tools.

What most children do by this age:

Social/Emotional Milestones

  • Notices when others are hurt or upset, like pausing or looking sad when someone is crying
  • Looks at your face to see how to react in a new situation

Language/Communication Milestones

  • Points to things in a book when you ask, like “Where is the bear?”
  • Says at least two words together, like “More milk.”
  • Points to at least two body parts when you ask him to show you
  • Uses more gestures than just waving and pointing, like blowing a kiss or nodding yes

Cognitive Milestones (learning, thinking, problem-solving)

  • Holds something in one hand while using the other hand; for example, holding a container and taking the lid off
  • Tries to use switches, knobs, or buttons on a toy
  • Plays with more than one toy at the same time, like putting toy food on a toy plate

Movement/Physical Development Milestones

  • Kicks a ball
  • Runs
  • Walks (not climbs) up a few stairs with or without help
  • Eats with a spoon

Other important things to 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?

Concerned About Your Child’s Development?
Act Early.


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. The American Academy of Pediatrics recommends that children be screened for general development using standardized, validated tools at 9, 18, and 30 months and for autism at 18 and 24 months or whenever a parent or provider has a concern.

If you or the doctor are still concerned:

  1. Ask for a referral to a specialist who can evaluate your child more; and
  2. Call your state or territory’s early intervention program to find out if your child can get services to help. Learn more and find the number at cdc.gov/FindEI.

Tips and Activities: What You Can Do for Your 2 year old
Begins to sort shapes and colors

As your child’s first teacher, you can help his or her learning and brain development. Try these simple tips and activities in a safe way. Talk with your child’s doctor and teachers if you have questions or for more ideas on how to help your child’s development.

  • Help your child learn how words sound, even if he can’t say them clearly yet. For example, if your child says, “or nana,” say “You want more banana.”
  • Watch your child closely during playdates. Children this age play next to each other, but do not know how to share and solve problems. Show your child how to deal with conflicts by helping her share, take turns, and use words when possible.
  • Have your child help you get ready for mealtime, by letting him carry things to the table, such as plastic cups or napkins. Thank your child for helping.
