Hi, We are heading to WDW in a couple of weeks. I need a sitter to watch my child. He will be sleeping in our room when we need a sitter. Does the sitter just "sit" there and read while the child is sleeping? I mean that's what they are there for, right? Also, is there a sticky topic with in room sitting options like who to call? Or a link to a page of the info? Maybe even what sitters are recommended? Thanks!
