The Growing Child Growth not only involves length and weight of a body, but also includes internal growth and development. A child's brain will grow the most during the first 5 years of life, reaching 90 percent of its final size. Growth also affects different parts of the body at different rates; the head reaches almost its entire size by age 1. Throughout childhood, a child's body becomes more proportional to other parts of his or her body. Growth is complete between the ages of 16 and 18, at which time the growing ends of bones fuse.
