Hi C.,
I can totally relate to your situtation. My son is 4; we have yet to find a toothpaste that he does not complain-that it burns his mouth. We even tried the Tom's all natural strawberry and that did not work. I was going to try the Jason organic/herbal toothpaste with aloe next. I even discussed this with my sons dentist; he said we do not have to use toothpaste, just so long as we do brush his teeth. So what I have been doing, is mixing the Pink bubblegum flavored ACT Rinse, with the water in his rinse cup (sometimes I add a very small drop of the crest mouthwash in it as well).....I dip the toothbrush in the water, brush until he needs to spit, rinse the tootthbrush, dip it again and so on. He has had no complaints with this approach as of yet. I know it sounds like a big production but for now it works for us. Our big challange is getting him to actually let me brush all of his teeth. He will not sit still or open his mouth cooperativley. If you find something before I do; please let me know? Good Luck!
