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 point to show things to others
•Can’t walk
•Doesn’t know what familiar things are for
•Doesn’t copy others
•Doesn’t gain new words
•Doesn’t have at least 6 words
•Doesn’t notice or mind when a caregiver leaves or returns
•Loses skills he once had
