Right, but what were they actually talking about?
My 10yo girl, when she was in Y5, knew what rape was. I think it might even be mentioned in Sex Ed. You know it happens to 10 year olds?
Sex in general - again, it’s on the curriculum. Age 8-10 is a great age for parents to talk about it, you get in when they’re not too embarrassed or giggly or horsing around or grossed out to listen, and importantly - ask their own questions.
Assault - it’s a fact of life, and an educated child is a safer one. You know that within their class, some child has quite possibly already been assaulted? My daughter and I have discussed risks and consent from this age and younger.
Prostitution? I remember explaining it to mine around this age as it’s when she watched Les Mis. It’s a good opportunity to talk about the lack of choices some women have, the danger of sex work, the over representation of previously sexually abused children and care leavers in the industry.
All of this was part of my Y5/Y6 chats with my daughter (now Y9) and I think she was better educated and safer for it. Also a lot of talk in last couple of years about pornography.
Honestly - you don’t need to move your child, you need to step up and parent your child.
