I know-ish a woman like this. Baby was only 7 moths old when she realised she was really a man. Told a large online group of friends of friends about it before anyone in real life. Clearly chose this group because it's full of TRA allies, FTMs, Afab NBs and munchie moms, so she got nobody to respond to tell her to cop the fuck on. They all basically coached her on how to be a man and what to do before she told her husband. Made sure she knew the "best" doctors and counsellors to go to. It's a fucking cult. I have lots of friends in the group, nice people, some are very intelligent about other topics. But they are full on cult members.
