Taking that first step, smiling for the first time, rolling from tummy to back, waving “bye-bye” — seeing your baby grow and learn before your eyes is a thrill for every parent. But these precious firsts also provide crucial clues that your baby is growing and developing normally.

To help parents and health care providers gauge children’s progress, the Centers for Disease Control and Prevention offer information about “developmental milestones” — movements, responses and behaviors that put your baby on par with what 75% of children can do at the same age.

Wondering if your baby is development is on track? Below is an abbreviated list of developmental milestones from the CDC for babies ages 2 months to 18 months.

  • Holds head up when on tummy

  • Chuckles (not yet a full laugh) when you try to make them laugh
  • Makes sounds like “ooh” and “aah” (cooing)
