My 15 month old dd absolutely adores my battery operated toothbrush and loves when I put it in her mouth. She has, of course, her own soft tooth brush that I use to brush her few teeth with but I was wondering if anyone knows of any battery operated kids toothbrushes available? Or is there a really obvious reason why they are very bad for kids that I'm missing? It seems to me that it is a good way to positively reinforce the whole teethbrushing experience.
