Child growth and development is a process that involves physical, cognitive, social, and language milestones. It occurs in five stages from infancy to adolescence. Physical growth can be measured by height, weight, and body mass index. Child development refers to acquiring skills in a sequential order, from simple to complex. Development depends on stimulation and parenting that fosters problem solving and social skills. Parents guide children's physical, cognitive, social, moral, spiritual, and language development through daily routines, play, and modeling positive behavior.
