Ds (2-and-a-half) has recently decided that brushing his teeth is a good battle ground and won't do it without a big fuzz and lots of encouragemnt. He tried one of those battery-powered toothbrushes at a friends house the other day and thought it was great, so I went straight out to get one. Of course, on the packaging it says for children AGE 4 AND ABOVE. Does anyone have any experience with using these electric tothbrushes on younger children? I guess what I want to know is if the age limit is a blanket legal thing or if there are real safety issues with a 2-and-a-half year old using electric toothbrushes? Thanks, Lorien
