Developmental Milestones
What Are Developmental Milestones?
Developmental milestones are skills and behaviors that most children reach by a certain age. They include physical, cognitive, social, and language abilities. Every child develops at their own pace, but milestones help track progress and identify potential concerns early. Routine well child visits are an important way to monitor these milestones. See our Well Visit Schedule to learn when your child should be seen.
