Developmental Milestones

Click an age below to see the milestones to watch for during the selected period of life, and find age-appropriate resources to support your child’s development! Remember that development exists along a continuum, so not every child will achieve every milestone at an exact time. Always reach out to your child’s pediatrician should you have any concerns.

Talk, Read, Play: The Foundation of Development

At the Rollins Center, we believe Talk, Read, and Play are essential tools to building a solid developmental foundation with a focus on language and literacy for children birth to 5. But what exactly does that mean? Check out our articles below to see how you can make a difference in your child’s language development. Learn more about these approaches and how they fit into your child’s development!

When to Talk to a Doctor

You know your baby best – don’t wait! If your baby is not meeting one or more milestones, has lost skills he or she once had, or you have other concerns, act early.

If you or your doctor are still concerned:

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