A child's first three years are very important and the way the child learns and develops during those years can make a difference in the child's future. Below are some developmental milestones for your child's first three years. Although each milestone has an age level, the actual age when a normally developing child reaches that milestone will vary. It is important to remember that every child is unique. If you have any concerns speak with your child's pediatrician about a referral to your community's early childhood intervention system.
