Thank you. And re: ADD, again, I watched DS almost walk into a door tonight because he was so busy looking at something else. Made me remember the time he walked into a lamp post at age 5 or so upon leaving a museum. He was so intent on studying the toy he just got that he did not look at where he was going. Is that ADD, or is that just hyperfocus? In any event, I think we'll try a more formal reward system. Surprisingly, homework is no problem this year, but I'd like to see him do more reading and writing. Thank you.
