Child development refers to a child's ability to perform tasks of greater complexity as she/he gets older. The sequence at which a child develops is orderly and predictable, but different children develop at different rates. Child development involves language, social and motor skills. Physical development in children refers to the development of their motor skills, which involves using their bodies. Physical development is defined by a child's gross motor, fine motor and balance or coordination skills.
