Sorry about this question, but I'm a relatively new mum due to having adopted - my two boys are 5 and 7. We're an electric toothbrush family, and I've been brushing both kids' teeth since the arrived with us over a year ago. The dentist whom we saw today was really pleased with the state of their teeth, but I think it's about time the oldest, in particular, started being a bit more independent with this. How did you go about this - supervision seems to be the most sensible approach, but is there any other advice you have?
