    Developmental Milestones
    You may be surprised by the average age when a child reaches developmental milestones. The process by which we reach these milestones is called maturation. Is there a way to "speed up" a child’s thinking process? The answer is no. Yes, it is important to provide babies and children with developmentally appropriate toys. However, thinking that the more toys a baby or child has, the smarter this child will become is not correct. Talking to children and playing with children are just as important as a stimulating toy. A child who develops very slowly and at a much later age than the average child may have something wrong physically.

    Maturation: The rate in which a person matures.

    Talk with your parent or grandparent or a person who would remember you as an infant. You may also have a baby book that you and your family member can reference together for this activity.Try to identify when you hit your developmental milestones.

    • How old were you when you began to walk?
    • How old were you when you began to talk?
    • How about sit up?

    Did you know there is an average age that all children, no matter what culture, reach these developmental milestones? Try the self-check below to see if you can guess some of these average ages. (Note: These are estimated ages and everyone reaches these development milestones at slightly different times in their childhood.)
