Developmental milestones are behaviors or physical skills seen in infants and children

Developmental milestones are behaviors or physical skills seen in infants and children as they grow and develop. Rolling over, crawling, walking, and talking are all considered milestones. The milestones are different for each age range. There is a normal range in which a child may reach each milestone.

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, act, and move (crawling, walking, etc.). Each child develops at his own particular pace, it’s impossible to tell exactly when yours will perfect a given skill.

Each baby develops in his own manner, so it’s impossible to tell exactly when your child will perfect a given skill. Although the developmental milestones listed in this book will give you a general idea of the changes you can expect as your child gets older, don’t be alarmed if his development takes a slightly different course.
