They love, love, LOVE going to the dentist.
Perhaps I should ease up on the threats and try some positive reinforcement.
"If you clean your room, I'll take you to the dentist!!"
P.S. I don't know why David's dentist-love surprises me every six months. This is the kid who had a tantrum when he couldn't have a flu shot. But Mary! Well, this is the girl who cried so hard at the dentist the first time that she vomited all over him. She's come a long way.
