i guess the bath one isnt essential, u can check with ur elbow
i would get a room one though, u can get them cheap, i got one from mothercare, its pink and gorgeous, they have a boy version aswell and a neutral one, it was dead cheap from what i can remember, its like one of those forehead strip thermometer things hehe
my house is quite cold so i need one cos i know she will be colder than i am and need different number of blankies in different temps and that so its easier really
the bath one i have is a little disney one that i got from tesco for dead cheap ages ago
