This morning, after Natasha had gone to work, E came into my room while I was getting dressed. He and R like to play with all of my hair clips, and he was doing just that, when he asked a question about which of the hair ties, bands, clips and pins were Tasha's. After I answered, I asked him, "Are you sure that you're okay with Daddy being Sunny?" He said, quite intelligently (he's 6), "Definitely. She's not as angry as she used to be."
I asked, knowing the right answer, "Did she yell more when she was a boy?"
E said, "Oh yeah. She yelled a lot and now she doesn't yell much at all. That means she's happier."
I said, "That means we're all happier since she doesn't yell as much, right?"
He said, "Definitely."
He promptly stuck a clip in his short hair and spun around a few times.
The lesson here is that if you have people in your life who doubt whether or not what you are "doing" by transitioning (or accepting it if you are the spouse) is good for the kids, ask the kids. They'll tell you the truth if you let them.
