I baby sit a lot of children. But sometimes I baby sit until 11:00pm some nights. Is it right if I should have a nap? I'm worried about something happening if I do...

If the children are asleep and you can manage a nap in a place where you would hear them if they were to get up and wander around or call for you, then I would suggest it's a better idea than to try to stay awake and not be alert enough to deal with an emergency. But check with the parents to make sure they're okay with it. They probably sleep while the kids are sleeping, so they might just say it's a fine idea. On the other hand, if they're a bit concerned about your not waking up because you might sleep too soundly, you will have to go along with their wishes. They are your employers while you're at their home with their children, so you have to adhere to any reasonable demands.
