I wasn't implying that babysitters just wanted to watch tv, only that he'll probably be put to bed by us anyway, so he'll be asleep (hopefully) and the babysitter won;t have anything to do except sit in a darkened room. I know when we've been on holiday I've found that fairly boring and ended up going to bed REALLY early, so I wasn't sure if that's what babysitters did too. Anyway, Tegam obviously did it when she was a babysitter so that made me feel better!
Thanks for your replies
