Any tips to get a 17mo to clean her teeth? She won't let me do it AT ALL, just clamps her mouth shut if I try to do it for her. She will take the brush (cute toddler toothbrush) and bite it and brush for maybe 3 seconds and then done. She's got about 6 teeth. Any tips for making her do it for a bit longer or letting me? I don't make a big deal out of it, try to sing songs, brush mine at the same time etc but she seems to be resisting more and more. She's not talking yet but she understands most things and definitely knows what I want her to do. She's a really content child, not difficult at all so I'm sure its me doing something wrong in the process!
