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 as developmental milestones. These are the parameters of different age of children, which gives an idea about the average estimate of the time when the child can be expected to have certain skills. Developmental milestones are a set of functional skills or age-specific tasks that most children can do at a certain age range.
