Oh my god I wish people had listened to me when I was that young. I wouldn't have had to have double-incision chest surgery. I wouldn't have gone through years of agony. I consistently expressed, as long as I remember, my gender variance until my peers went through puberty. Then I just kept it quiet and tried to hide it.
I count myself lucky that my relatives (who are extremely gendered in the roles) allowed me to be a boy and to do the boy things, but that would've been heaven.
I like what the one parent said, "if it turns out to be wrong, we can transition back". She's right. I don't think it's a great idea giving kids hormones that might have irreversible effects; I do think they should be pretty grown up when they make that decision, but hormone blockers would prevent a lot of agony. And all of us who've been through it know what agony it is going through the wrong puberty. I started mine at 17 - later than most kids. That fact wasn't traumatic. Going through it was awful.
