AIBU to literally hold him down and force him to brush his teeth? He is 18 months old, doesn't eat much sugar but still has fruit and the occasional treat. Regardless, I needs to brush his teeth. It's been a week since I've brushed then properly and haven't been able to because he screams and clamps down on the toothbrush. I've tried getting him to brush his own teeth whilst I do mine then brush his properly after, different toothpastes in case it was the taste, different toothbrushes. This aversion to teeth brushing has been on and off since he was about 1. Can anyone advise?
