. >> 12-year-old roxie castro was born biologically a boy. >> right around the age roxie came in and said she felt like a girl. it was devastating for her. we would force her to wear what we bought her more masculine clothes and she would cry. she would tell us, that's not me, mom. >> reporter: she knew? yes, yes. at the age of 8, roxie's parents allowed her to begin identifying as a girl. because she transitioned so young, roxie hasn't experienced the same situation that other children have but like many, roxie's parents have had to make a transition of their own. >> this is 2011. we are still identifying him as he. and i said compromise on how the clothing, if you can see the shoes were flowery and stuff. that's how we sort of negotiated. because we found out, and we let her be at an early age. a lot of people might not think, oh, there's a loss there. but there is. you always think about the what if. and you just -- those feelings are not communicated to her. memories that we have. you can't share with other people. because you don't want to make her feel uncomfortable. >> reporte
