Until now 2 year old DS has been great with cleaning his teeth. Admittedly he chews more than he brushes but he still has a go. The back of the head of the toothbrush was soft and chewy so it was nice and comfortable for him. However, he has now chewed it to death and needs a new one. I bought a new brush but after trying a couple of times and realising it hasn't got the soft bit he won't use it and just reverts back to the old one. I have hidden the old one but then he refuses to use anything. I have bought a Thomas brush but that has the same problem. I have tried finding the exact same brush again but I can't find it anywhere. Does anyone have any tips on getting him to use a new one so I can throw his manky one away?
