I'm sorry if this comes across offensive but I am incredibly naive when it comes to these kinds of issues.
DD has a boy in her class, they are in reception year. At the start of the year she asked if the DC was a boy or girl and I could only answer as being not sure. The mother is very quiet so I hadn't heard her refer to the child as a he or she. The name is more 'boy' but could possibly be a girls also, the child wears a mixture of girls and boys uniforms and on non-school uniform days they wear girls clothes.
DD now knows he is a boy, but he is apparently allowed in the girls toilets and DD at 4 doesn't understand why, she also said a few other boys see this boy able to go in the girls and the boys follow.
She has asked a few times why he does tis etc. and I don't know the right answer, they are likely to be in the same school year for the whole of primary so they are questions I need to answer but I don't know how.
Would the mother be offended if I talked with her about it??
