I read on one of the bedwetting threads about the mattress protector from www.toysrus.co.uk
ref 187410 £12.99
and it looks v useful, but from the pic it doesn't look like it's attached to the bed at all. Is there anything attaching it? I don't want to get one and find that it just slips off before she's even gone off to sleep!! Also, if she were to take it to a friend's for staying over - just in case - do you think the friend would laugh at her?? (we're talking 6 yr olds). Thanks for any advice.
