Six-year-old Sophie says she has always known she's a girl. "I used to be Yoshi," she says. "But I didn't like being called Yoshi." And she didn't like being called a boy.
Sophie lives with her family in Bellingham, Wash. Her mother, Jena Lopez, says she started seeing the signs before Sophie turned 2.
"She'd say things like, 'I'm a she, not a he,' " Lopez says. "She would cry if we misgendered her. She'd become angry."
