You are great for supporting your child. My wife is good at any orientation, then she does not understand anything about gender identity. I try to talk to her about these topics, because anything can happen. In your case, you have a strong enough past that influences you and will always influence you. Here it is important to understand for you and your husband what is more valuable for you: to follow the canons or to improve relations with your own child. In any case, I wish you good luck!
