I was thinking this too. I feel that ADHD is over diagnosed in this country and it's because parents are getting too fat and lazy to help expend a child's energy. I have fur babies and I've learned that a tired pup is a good pup and a tired kitten is a good kitten. I'm sure the same applies with children. They can't calm down if they can't use their energy, especially when they're fueled by junk food.
