I’ll offer support.
My DD identifies as non/binary - has kept her original name but prefers ‘they’ as a pronoun. She is at uni so I don’t have to use it much & don’t really at home. Dh will never use ‘they’, he thinks it’s a load of BS.
But having said that I don’t really discuss the whole thing with her as it’s annoying for both of us as I come from a different viewpoint and generation, although I support, I don’t affirm. She was 18 when she ‘came out’ and also identifies as bi - although def more towards guys, not sure she’s done more than kiss a girl, maybe not even that.
Questions;
is your daughter in a relationship, do you think being trans impacts romantic relationships
did you see any signs of them being trans growing up - like preferring to play with girls, liking ‘girls’ toys etc.
Whst does your wider family think of the transition?
I see you said she’s autistic, it’s massively common in the autistic community compared to NT community / do you think autism is a factor?
how did you react when she came out?
