I don't think I'm BU - more for traffic.
How does your school navigate changing into PE kit? I believe some schools allow children to go in dressed in kit on PE days.
DD and her mixed class all change clothes together. She is in Y3 and I think the DC are becoming more aware of their bodies (and the difference between genders) at this age. DC sometimes asks for privacy from me when changing at home which I obviously allow.
Yesterday DD told me a classmate (boy) told her to pull her pants down while they were changing. I'm of the mind that is it natural to be curious at this age, but I feel it is more than likely becoming uncomfortable for the class.
I think I should raise it with the school...
