We encourage you to pay attention to the type of toothpaste you give small children; fluoride levels vary from product to product. 

For children under age 2, the American Academy of Pediatric Dentistry endorses a tiny smear of fluoridated toothpaste. A pea-sized amount is recommended for children under six years of age, but read the fine print on the tube for recommendations. You should also keep it out of reach; kids are sometimes tempted to eat toothpaste.
