Hi Alena
Well, I just got back from spending fathers day with my three children, who live near Kansas city. (Ages 16,15 and 12) The 12 year old is fine with me, we still have fun. The two oldest, well their dad was always weird, but now I've taken it to a new level, in their eyes. Their concern I think is being see with me in public and meeting a friend. It is a factor for them. It was not all that easy a trip and I'm not sure when the next one will be. When I told them in april about me being TS, they were pretty cool. A few months later and reality is hitting home for them. It's not easy, but its not always hard either.
That said, I would still have transitioned, it's who I am and better me as me then as a lie. Though not everyone in my small family agrees with me.
One thing with HRT, It's harder for people who see you every day to spot changes as it's pretty gradual. Though breasts will tend to give it away after some time. It's the people that don't see you but once every 4-6 months that will notice first.
Anyway got questions, Ask away, and good luck with what ever you decide.
