She screams and clamps her mouth shut! Any ideas what I should do? I'm torn between not pushing it too hard and making a game out of it with the hope that she will eventually learn to enjoy/accept it ... and just pinning her down and doing it because I'm concerned about the effect it's having on her teeth all these times that she hasn't had it done properly. At the moment I am doing a mix of the two, which probably isn't the best.
