DD (6) has been invited to a sleepover party the saturday before Christmas. It is a friend from school and I know her mum so I don't have any concerns regarding being looked after etc. however I was quite surprised that she would do this with 4 6 year olds (am I being old fashioned) but I don't think dd is old enough. On top of thinking that she is too young MIL/FIL are visiting that weekend (in lieu of Christmas) and i think it's a bit rude if dd is away for much of it - we only see then about 3 times a year. I imagine that dd with get very little sleep (she still needs at least 11 hours) and will spend the next few days tired and grumpy.
I have told dd that I am not sure she can go - grandparents here, going to a restaurant and she just looked sad said she really wanted to go but didn't kick up a fuss.
Does anybody have any experience of this? Am I being an old fuddy-duddy (I didn't do sleepovers until I was about 10)? Should I just tell her that she's too young but she can have sleepovers when she's 7/8 whatever?
