Developmental Milestones 

Every child is unique and has an individual rate of development.

The below chart represents, on average, the age by which most children will accomplish the listed skills. Children typically do not master all items in the category until they reach the upper age in each age range. This information was provided by the American Speech, Language and Hearing Association (ASHA).
