Baby Developmental Milestones

​​

• Skills such as taking a first step, smiling for the first time, and waving “bye bye” are called developmental milestones.

• According to the Centers for Disease Control & Prevention (CDC), developmental milestones are things most children can do by a certain age.

• Your doctor checks these milestones at every visit to learn about your child’s health.

• Children reach milestones in how they play, learn, speak, act, and move (like crawling and walking).
