Motor development is taking coordinated muscular control necessary for physical activity. It follows two general principles. The first is the cephalo-caudal principle, which means that part of the body closer to the head to develop before the part closer to the foot. For example, as the baby learned to crawl, first to do this by using their weapons less developed and only later their feet. The second factor governing motor development is the proximodistal principle, which means the part closer to the center of the body of the baby will develop new parts farther away. For example, in reaching for objects, infants use their first further develop arm s and then their fingers, that control develops later.

Most sequence developing motor skills early is managed by a process known as maturation. Maturation is a development occurs in a sequential and orderly fashion due to a genetic plan. A child’s first step is a good example of maturity, because it is provided by the development and control of many sets of activities of the flesh. The sequence of motor development and control that results in walking, to a large extent, controlled by maturation.
