My little girl used to love it when I brush her teeth but now that she's older (20 months), she fights it 80% of the time. I've tried several tactics including brushing alongside her to show how fun it is. Currently, I hand her one toothbrush while I hold another and we take turns brushing her teeth. This works now but I can tell that she's getting bored of it and I'm running out of ideas.

What tooth brushing tips and tricks work for you? Also, what are your thoughts on electric toothbrushes and is she too young for one?
