We've had tons of these conversations. The best things I've done a) tell him all the crazy things I used to obsess about and keep my mother awake over when I was young. b) tell him all the crazy things I still worry about. He laughs about a and b. And c) I tell him that he's just really smart and with a brain like his (and mine) worrying about stuff is part of the package and he, like me, will learn strategies to make peace with his brain.

That, I guessm, is keeping it normal. Our normal.
