I have a friend who has a child that is over 2. She claims he has never slept though the night and wakes most nights and then doesn't go down again, also he doesn't nap. She constantly talks about how he doesnt sleep yet When I questioned her about why he thought he didn't sleep she seems to think its normal and that it's something 'some children do'. I worry about the child as it seems try are given a lot of medicine whether they show signs of needing it or not. Is it normal?
