Adults exercise enormous control over children's bodies, including how they sit, walk and run, what they wear (sun hats, make-up, glasses), their hairstyles and whether or not they can have their ears pierced. It is taken for granted that children's bodies may be touched (in socially acceptable ways by specific adults): they are washed, fed and dressed, have their heads patted and hands held, are picked up, cuddled and kissed, and they may be disciplined by smacking.
