Developmental Milestones

Developmental milestones are a set of functional skills or age-specific tasks that most children can do at a certain age range.  Although each milestone has an age level, the actual age when a normally developing child reaches that milestone, can vary quite a bit because every child is unique.


Please Note: The ages shown in the PDF table represent guidelines only and are not absolute.
