Haha, pretty much the same dynamic with my wife here regarding our son.

Either of us would care about him being transgender or not. As long as he's happy with who he is. Sexuality is a spectrum, not something black and white.

However, my wife worries a lot about him not eating as much as she'd wish him to. And being the shortest in his class. I can tell her as much i want about genetics, as i was also the shortest one as a kid, the cultural pressure to be tall removes one's ability to realize he eats well for his size and nothing much to do against genetic predisposition. He's just so distracted at dinner table and it takes a lot of patience from either of us to give him the time he needs.
