At what age do you find you can send a child to wash (including hair) and expect they will make an acceptable job of it? I've no real idea, the books tell you never to leave a baby alone then never really come back to the subject! I don't really mean for having several children and an older one will remind the others to do the job, more so sending a child (comfortably older than 5!) up to bathe and expecting them to return clean. What age did yours manage that?
