Document Summary
Around 3 children take on more adult-like body shapes. Boys have an edge with regard to height and weight until puberty. Major improvements in gross and fine motor skills. 1) motor control of the head comes before control of the legs. This head-to-tail sequence is called the cephalo-caudal trend. 2) motor development proceeds from the entre of the body outwards; i. e. the head, trunk and arm control is mastered before the coordination of the hands and fingers. Physical growth follows these same trends throughout infancy and childhood. Five big achievements: child becomes fully locomotor, ball-handling, fine eye-hand coordination, walking leads to running, jumping, hopping, galloping, and skipping, climbing evolves from creeping. Age 4: child has almost achieved an adult style of walking. Age 3: child attempts to run, albeit awkward in style and lacking control turn. Age 4-5: child has more control over running and can start, stop, and. Age 5-6: almost level of an adult.
