My Dd is 7 and I just can’t imagine me being ok with her going to a sleepover (not yet at least) I know the pressure will start in a few years, plus the phone pressure.
I also always feel uncomfortable when checking out groups for Dd, for example she wants to go to an adventure type club two friends go to, but the staff are mainly male and it puts me off. There are also three male staff at her school
(not teachers, but door staff & library) and I sometimes wonder about them.
I never pass any of this on to Dd and she has quite a free life, plays at friends houses on the street etc
You just see so many awful things about how kids can be treated and evil people out there.
