My baby now has six small teeth. I'm trying to brush them but he clamps his mouth shut when I try. I've tried playing games with him with the brush, letting him play with it etc to no avail. I've resorted to rubbing toothpaste on his teeth and risking getting bitten! I bought s standard baby toothbrush but can't remember the brand but it seems quite hard. Can anyone recommend a soft toothbrush or any tips on how to successfully brush his teeth?
