Document Summary
We spend about 20% of our lives-all of childhood and adolescence-growing physically. Children depend less on others for care, they"re treated differently by adults, and they view themselves as older and more mature. Pete has just had his 15th birthday, but, as far as he is concerned, there is no reason to celebrate. He is embarrassed by his appearance, particularly in the locker room, where he looks like a little boy among men. From birth and 2 years, average height increases from 19-32 inches; 22 pounds. (boys achieve half their adult height by 2 years, and girls by 18 months. Growth is fairly steady through the preschool and elementary- school years: about 3 inches and 7-8 pounds each year. As children grow, their body parts develop at different rates: the head and trunk grow faster than the legs. Infants and toddlers have disproportionately large heads and trunks, making them look top-heavy compared to older children.
