Fibbke I did have to explain fgm to my DD1 when she was 8 as there was a poster on the train about it.
It was not easy, the bit I struggled most with was why.
I also told her that it was in certain communities, it's pointless to have girls thinking that this is a widespread thing for girls in general, when it isn't.
I would have thought that the pants rule covers it tbh for this age, stuff about secrets and so on the stuff I think they get. Naming specific practices and crimes eg rape fgm incest grooming sexual exploitation etc with outlines is too much for this age I'm not singling out fgm.
FGM is in fact only covered at ks3 at the moment. I see a lot of posters want it moving to ks2 named as a specific thing and with outline which is out of step with the way other things are dealt with.
The posters who think that the parents have been overly protective if their child would be upset by facts of fgm at 9 are out of step though I think, with the best comment being that 9yo who play with soft toys lack resilience. 9 is still v young. Lots of 9yo girls and boys are still playing with toys at that age.
And yes lots of children have lots of bad stuff happen all the time, but I don't see why the generalised pants for stuff is OK for all but this one topic where specific info needs to be given.
I am also really against the idea of letting kids think this is a general risk for girls in UK it is not, irrespective of what happens in some extreme USA christian sects.
