James has not really lined up toys in order, the way some kids on the spectrum do, but he has a very definite idea of what things go where and can obsess over things out of place.
Like tonight, when I made him change his seat on the way home, because there were bags in the back, where he's been sitting for the last few months (ever since he and his sister got too big to share a row in the car).
Oh. My. Goodness.
Twenty minutes of "I don't like _insert everything under the sun_" and "let me out Right Now!"
aaaaaaaaaaaaaaaall the way home.
And then he was fine. I am working on that myself.
