Developmental Checklist

This developmental checklist provides information on what a child may typically be doing between the ages of birth to five.

If your child is not meeting “developmental milestones” you may want to have him or her evaluated by a physician.

If your child is under the age of three, call First Steps, Indiana’s early intervention program for infants and toddlers with disabilities or at risk of disability.

If your child is over the age of three, call your local school. He or she may be eligible for early childhood special education.
