I'm finding it really hard to brush my 21 month old DS's teeth - he refuses to have the toothbrush in his mouth at all sometimes. I use an electric toothbrush, and he loves this and is always trying to get me to use that for him instead of his toothbrush. I looked at getting one for him, but they all say not for children under the age of 4.
Does anyone know why? Are they bad for them for some reason, or is it a legal health and safety type thing that will be fine as long as I'm supervising?
