My first daughter told me she was struggling with gender dysphoria at age 14, and had been since age 10 (that rang true because she became troubled at age 10, and I thought it was because of early onset puberty). I talked with her about her feelings. I told her that girls often feel uncomfortable about their changing bodies, and it doesn't necessarily mean they are trans. I brought her to a good trans youth group. The youth portion split into 2 groups: people that wanted to talk about trans issues, and people that just wanted to socialize (she always chose the social group and never showed interest in medical transition). And there was a parent group at the same time for my support. I called her by the names and pronouns she wanted. I let her dress and cut her hair any way she wanted. At 16, she had grown her hair out, wearing skirts, nail polish, jewelry, bows and flower crowns, and said she feels Agender nonbinary and wants people to alternate between she/her and he/him. She now has a very healthy body image. And I was and always am a person she can openly talk to. She made a friend from the group and then stopped going. My younger daughter came out as gay at age 11 (before she knew her older sister came out to me as trans). Then at 14, she also came out as nonbinary. So, I'm doing the same thing with her, and using they/them pronouns. And I'm talking about the importance of waiting to do anything permanent and the risks involved. They wanted testosterone to change their voice, so I bought them a book about voice training, and will get them voice lessons. Because that's not permanent. And I have them both in therapy. And evaluations for suspected autism and mental health challenges.
