I’m trans, and have also worked with trans kids. Sometimes outed myself when it was safe - showing young trans men that yes, you can be a man.

It really comes down to “what name and pronouns would you me to call you by?”

If you want to go above and beyond: “would you like me to correct/step in for you if someone calls you by the wrong names/pronouns?” I feel this is a place where adult advocates can have good impact.

“Does your family know/should I use your legal name when talking to your family?”

See the child as a person who deserves dignity and respect, who is in a vulnerable position and does need unconditional support. Which is true for all children. You don’t have to put up a progress flag or wear a rainbow pin - these can certainly be very good things to do - but at the end of the day, just honor the child.
