Jacob has 8 toothie-pegs and so I am madly trying to clean his teeth too, but he hates it and purses his lips shut. I just let him play with the toothbrush in the bath (since it automatically goes into his mouth anyway) and I try to move it a bit whilst it's in there, otherwise I try to get a face washer and at least get my finger in there to try and rub them with that (at my own risk....ouch!).

I've heard for older children one way is to turn it into a bit of a game, e.g. who can make the most bubbles with all the frothy stuff?! LOL
