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:

•Doesn’t show a wide range of emotions
•Shows extreme behavior (unusually fearful, aggressive, shy or sad)
•Unusually withdrawn and not active
•Is easily distracted, has trouble focusing on one activity for more than 5 minutes
•Doesn’t respond to people, or responds only superficially
•Can’t tell what’s real and what’s make-believe
•Doesn’t play a variety of games and activities
•Can’t give first and last name
•Doesn’t use plurals or past tense properly
•Doesn’t talk about daily activities or experiences
•Doesn’t draw pictures
•Can’t brush teeth, wash and dry hands, or get undressed without help
•Loses skills he once had
