DS2 flatly refuses to let me brush his teeth. Either he wants to do it himself (which consists of about 3 strokes of the brush) or he clamps his mouth shut. It's not the toothpaste as he is happy enough to eat that out of the tube when he can get his hands on it! DS1 has been brilliant ever since I told him that the bugs would eat his teeth if they weren't brushed properly, but DS2 simply says "I don't want teeth" (he is 3!). Any suggestions?
