AIBU to not feel comfortable with letting my 9 year old (just turned) go to another 9 year olds party which is an hours drive away (with her parents) and 6 other friends. It's a public place they are going too which will be very busy, espec in school holidays. My mind always thinks worst case scenario. She is sensible, as sensible as a 9 year old can be. I don't want to hold her back but feel she's still a bit young, maybe end of primary school age is more appropriate for these kind of parties?? All her other friends, including her, had their parties at home.
