How do you brush a 13 month old's teeth? We got a late start, I am very sad to say, and now I have to figure out how to do it. She will wiggle her little toothbrush around in there a little, which is great, but we're not getting anything clean. She won't sit still and has tantrums. She hates fingers or things put in her mouth. Plus the only "toddler safe" toothpaste we could find has SACCHARIN in it. Ew! I am worried because she nurses a lot during the night, and has for all 13 months. HELP?
