What is the best toothpaste for a 2-year old? My son tends to swallow his toothpaste that's why im quite reluctant to let him use regular kids toothpaste.

You can use organic toothpastes like Human Heart Nature's. HHN's products are guaranteed 100 percent all natural however, in the case of their toothpaste, it's 99.67 percent. But hey, that's not bad, right? :)
