We have tried many different ways of trying to get the kids to brush their teeth without throwing a fit when its time to give up the tooth brush. They all like using their tooth brushes, but sometimes get mad when its time to put them up. They also like to brush other things besides their teeth like their hair, the floor, wall, etc.. So we have tried several approaches to get them to brush their teeth and not get mad when they are done.
One of the most recent approach which worked out really good was we put a blanket on the couch and turned on Bubble Guppies and they sat their glued to the couch for quite a while just brushing away and actually handed over their tooth brushes when the show was over to go to bed.
