Developmental Milestones

From babbling to walking, your child is growing very quickly! The way your child plays, learns, speaks, acts, and moves all show how your child is developing.

About Your Child's Development

Below is a timeline of developmental milestones. Developmental milestones are things most children can do by the time they reach a certain age. These milestones were developed by the CDC to serve as a quick reference. They can tell you where your child should be and where they are headed next. 

It’s important to remember that all children develop at their own pace. A developmental screening is the best way to know if your child is on track. If you have questions or concerns about your child’s development, or want a developmental screening, contact your pediatrician or call Help Me Grow Inland Empire at 1-888-464-4316.

This information on developmental milestones is from the Centers for Disease Control and Prevention (CDC), “Learn the Signs. Act Early.”
