Developmental Milestones

Developmental Milestones

Developmental milestones offer important clues about a child’s developmental health

Reaching milestones at the typical ages shows a child is developing as expected. Reaching milestones much earlier means a child may be advanced compared with his or her peers of the same age.


Not reaching milestones or reaching them much later than children the same age can be the earliest indication that a child may have a developmental delay.
