What is a developmental milestone?
Developmental milestones are a set of functional skills or age-specific tasks that most children can do at a certain age range. Your pediatrician or primary health care provider uses milestones to help check how your child is developing. Every child is unique. Therefore, although each milestone has an age level, when a developmental milestone is achieved varies from child to child.
