Document Summary
Growth in height in weight is the obvious physical change that characterizes early childhood. The average child grows about 6. 4 cm in height and gains between 2. 2 and. As we age in childhood the percentage of increase in height and weight decreases with each passing year. Girls are slightly smaller and lighter than boys until puberty. During the preschool years we begin to thin out and our body fat shows a slow steady decline (loosing baby fat). One of the most important physical developments during early childhood is the continuing development of the brain and nervous system. Brain growth continues, but at a slower pace. Brain development at this stage allows us to make considerable strides in language development, planning, and reacting to and interacting with our environment. By the age of 3 our brain is three-quarters of its adult size. By the age of six the brain has reached 95% of its adult volume.
