Important Milestones: Your Baby By Two Months

In 2022, CDC’s milestones and parent tips were updated and checklist for ages 15 and 30 months were added. For more information about the 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 2 months 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  [755 KB, 2 Pages, Print Only] below.

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

What most babies do by this age:

Social/Emotional Milestones

Language/Communication Milestones

Cognitive Milestones (learning, thinking, problem-solving)

Movement/Physical Development Milestones

Other important things to share with the doctor…

  • What are some things you and your baby do together?
  • What are some things your baby likes to do?
  • Is there anything your baby does or does not do that concerns you?
  • Has your baby lost any skills he/she once had?
  • Does your baby 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.

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 month old

As your baby’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 baby’s doctor and teachers if you have questions or for more ideas on how to help your baby’s development.

  • Respond positively to your baby. Act excited, smile, and talk to him when he makes sounds. This teaches him to take turns “talking” back and forth in conversation.
  • Talk, read, and sing to your baby to help her develop and understand language.
  • Spend time cuddling and holding your baby. This will help him feel safe and cared for. You will not spoil your baby by holding or responding to him.
