When my sister became my brother, there was a transition period where I had to get used to saying "he" instead of "she".

It took a while. I'd often slip and say "her" instead of "him". I just kept correcting myself.

Eventually I got used to saying "him", and he is now definitely all he/him and my brother. He's a great guy!

(That may not be a direct answer to your question. Just wanted you to expect there'll be a transition period where people get used to saying the other thing.)

I think my mother had the hardest time. She went next door to break the news to our neighbor. She hemmed and beat around the bush, and the neighbor eventually said, "Oh for Christ's sake, I already know! She's a he! He's a tranny! We've known this for years! He's a wonderful kid and we love him!"
