I am so happy I gave this toothpaste a try. My son got his first tooth when he was 3-4 months old. By the time he was 12 months old, he got full set of teeth. But brushing teeth has been a huge struggle. I've tried everything from using different type of toothbrushes to puppet shows! I began worrying about possible cavities he maybe developing from not brushing his teeth well. Since I introduced this toothpaste to him, it has been so much easier to brush his teeth. He seems to enjoy the taste and he let me brush all his teeth which is very very hard to accomplish! Now he opens his mouth when I show him this toothpaste.
