My son Arthur is a transgender boy. (To be clear, just because Arthur is transgender does not mean he will be queer. Gender identity and sexual orientation are separate, and
there are transgender people who are straight.) He was assigned female at birth, but his non-conforming behavior was clear and consistent from day one. It started with his hair. He hated wearing it long, and he hated it when we did anything with it. No ponytails, no braids — nothing. He also refused to wear dresses and skirts.
For a long time, he didn't name his gender when asked; usually, he just changed the subject. But then, when he was about 3, he said he was a boy. And he never wavered. Shortly thereafter, he told us he wanted a new name, a boy's name. We let him pick one, and he picked Arthur. A few months ago, his name change went through the courts. It's now official.
