Non-binary biological boy at DD's girls' school: toilets

[ItsHitTheFanNow]

Hello, a non-binary biological boy has started at DD's girls' school.

Are there any regulations around what toilets they need to use? I just wondered what the actual legal position on this is. Thank you.

Theyre not a boy. Theyre non binary.

The child identifies as non binary, a recently made-up characteristic. He is still a boy. If he identified as a duck, would you insist they give him a pond?
