Just happened to read a posting about this mouthwash and the firefly brush.  Went to my local market and needed toothpaste.  I decided the girls needed new toothbrushes so I wandered over to the kid section and I saw this mouthwash there on the shelf.  So, I bought some, I wanted to see how it worked.  Came home, tried it out for myself before the kids came home and thought it was really "cool."  The girls tried it and they both agreed that they wanted to brush their teeth four times a day!  They loved it, and get grossed out when they look at their blue teeth.  Thanks for mentioning it, and the kids will WANT to brush their teeth!  Got mine right off the shelf at Super Stop and Shop.
