What can cause cavities in babies and toddlers?

The American Association of Pediatric Dentistry (AAPD) explains the cause of baby bottle syndrome: “Frequent bottle-feeding at night, ad libitum breast-feeding, and extended and repetitive use of a no-spill training cup are associated with, but not consistently implicated in, Early Childhood Caries (Cavities).” This means, don’t allow your child to fall asleep with a bottle or cup filled with any liquid, except pure, unsweetened water. Best practice is to fall asleep without a beverage.
