I think it is really noble of you to seek consensus and think about your baby. Your baby should come first no matter what.
Some spouses are more understanding than others. But they cannot really understand what it feels to be in the wrong body. Some therapists can be counter productive in the sense that some people trust them blindly because they are therapists, however wrong they could be.
I'd try to take baby steps. Watch some trans stuff together, that always helps, paint your nails with transparent nail polish, things that will soothe your dysphoria a bit, I agree w/ the hair removal idea. That's spot on.
Make her part of your changes, in a positive way. The more she gets into it, the more she will realise that we are not freaks, we are normal people with a great desire to live our lives without having to ask for permission.
That said, however, when one CHOOSES to be in a relationship, one should look after their partner. It's a 50/50. So, in my humble opinion, both should negotiate and reach a point where both feel comfortable.
Big hugs.
