A toddler is a child between the ages of one to three years old. During this period, the child learns a great deal about social roles and develops motor skills.

The toddler developmental timeline shows what an average toddler can do at what age. Times vary greatly from child to child.

If a child is 'behind' in some areas, do not consider it a problem without first consulting with a professional.
