DD9 has made friends with a girl who is new to the school and has been invited to a birthday sleepover next weekend. There will be 4 girls from the new school and a couple from her old school. As the girl is new to the school, I have never met the daughter or the mum and it doesn't sit comfortably to let her stay have a sleepover when I don't know the family at all.
Have tried to look out for friend/her parents at school drop off but she gets the school bus, so that didn't work!
DD is desperate to go - am I being overprotective to say no or should I let her go?
