Changing for PE year 4

[HowAboutTheLittleSpoon]

DD has started year 4 today, age 8. Over the summer I've noticed she's started puberty, everything but periods. Obviously she's quite young, but also quite a shy, reserved child and often talks about a group of "silly boys" in her class (same class as last year). At her school they still change together in the classroom, I've approached her teacher this afternoon to see about the possibility of the girls and boys splitting up to change/wearing their kit to school on PE days but she says no to both.

Can I ask what your children's schools do around a similar age please?

Nspcc pants rule is good to discuss, thanks

I’d stand firm on this. Children have a right to have their body respected in this way. ‘Supervising’ changing for PE simply needs a timer being set for them to ensure no messing, or if known to be a challenging group, a teacher listening outside. No one needs eyes on.
If the teacher is female, it would be reasonable to send the boys to the changing room if there’s only one.
