It's getting difficult to brush my toddler(about 18 months old)'s teeth. I switched to use the small, soft tooth brush (instead of finger brush) a few months ago. She keeps biting on the tooth brush and "tasting" the edible toothpaste (which does not contain fluoride) while brushing. anyone can share their experience of how to get brushing a bit easier (at least I can "clean" the teeth) ? And, any idea of how to teach them to spit out after rinsing ? I guess it's almost time to use fluoride toothpaste (or not?).
