Thanks, all. Hadn't come back to this thread for a bit but am coming back out of frustration. Tonight, he is bawling (BAWLING!) because daddy tried to help him with a math problem that he was doing for fun. Daddy gave him part of the answer and apparently, he ruined it for DS6. "But I loved that problem, and you ruined it! It was a 'good' problem! I loved that problem!"
