Developmental Milestones

Skills such as taking a first step, smiling for the first time, and waving "bye bye" are called developmental milestones. Children reach milestones in how they play, learn, speak, behave, and move (crawling, walking, etc.).

Check to see if your child is achieving these typical milestones at each age level:


Act early by talking to your child’s doctor if your child:

•Can’t jump in place
•Has trouble scribbling
•Shows no interest in interactive games or make-believe
•Ignores other children or doesn’t respond to people outside the family
•Resists dressing, sleeping, and using the toilet
•Can’t retell a favorite story
•Doesn’t follow 3-part commands
•Doesn’t understand “same” and “different”
•Doesn’t use “me” and “you” correctly
•Speaks unclearly
•Loses skills he once had
