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 try to get things that are in reach
•Shows no affection for caregivers
•Doesn’t respond to sounds around him
•Has difficulty getting things to mouth
•Doesn’t make vowel sounds (“ah”, “eh”, “oh”)
•Doesn’t roll over in either direction
•Doesn’t laugh or make squealing sounds
•Seems very stiff, with tight muscles
•Seems very floppy, like a rag doll
