Congrats! My mom also picked my middle name, err, sort of. My folks didn't know what kind of plumbing I'd have before I was born, so they prepared with a girl name and a boy name (which is actually gender-neutral, only they didn't know that then). When I came out to my mom, having already started going by the masculine form of one of my potential girl names, she said she felt should have given me the boy name in the first place, so I'm tacking it on as a middle name for now. I like it so much, I just might switch them if I legally change it!
