Going through this field myself. I have a 12 year old daughter from my first marriage who recently came out as bi, and while my ex- has handled that well, she freaked out a bit when my daughter expressed a desire for breast removal. Seeing signs in that direction? I came out to her, albeit unbeknownst to my current wife who wanted me to wait. She took it mostly silently, but I thought well, and found out that I picked her up yesterday from spending the day with a trans friend. On her recent birthday, we hosted a little party for her, with friends of both genders having an extended makeup session unprompted mid-gathering. So, I think she'll be fine. Now to wrap my OWN head around not being "just" a CD, as I'd told myself for decades.
