While we are talking tricks - any hints on brushing teeth? B HATES it - I mean with a passion. He'll suck on a tooth brush no problem, sometimes he'll let me brush his front teeth, but that's it. He'll let me put my fingers in his mouth, and we did the whole brush the gums as an infant thing but as far as brushing - nada. To really brush I have to restrain him which means I don't brush his teeth nearly as often as I should. Any hints?
