I'm a nanny, and I watch two kids, ages 2 & 6 from 8a.m. to 7p.m. Monday through Friday. Both kids are over tired every day. The 6-year-old screams all through the morning and spends most evenings in tears. The 2-year-old has activities every morning and while he is very well tempered in the afternoon after a 3-hour nap, he spends most of his hour long lessons crying in a corner. The parents have decided the 6-year-old just can't sleep and there's nothing they can do, but on the nights I've stayed late I was firm with her that she had to go to bed and she's always fallen asleep by 7:30. But when they put her to bed they'll let her stay up and watch tv until 9-11 p.m. when she says she's not tired or let her take the iPad to her room. As for the 2-year-old, he's started asking if he can go to sleep at 5:30 like clockwork and he's always told no, kept up until 7:30 or 8, and then wakes up at 5 the next morning. I think both parents feel guilty about how rarely they see there kids so they keep them up at night, but the kids and I are suffering for it every day. It's really gotten out of control, but the parents are extremely sensitive when it comes to corrective criticism, so I worry about saying anything to them. What can I do?
