Developmental Milestones

Parents: Being a parent is one of life’s greatest experiences. Use this guide to see just how your child is developing. Every child grows and learns in his/her own way and at his/her own pace. If your child cannot do two or more things at his/her age level, you may want to get more information. A good place to start is your local Intermediate Unit.
