Growth From Three to Six
Captions available
The idea
From three to six, US children grow about two to three inches and gain four to five pounds a year, reaching about forty-five inches by six.
In practice
A round-bellied three-year-old becoming a longer-legged, leaner six-year-old.
Where people slip
Proportions shift toward an adult's: the head's share of body length keeps falling as the legs lengthen.
