To prevent tooth decay in young children, the American Academy of Pediatric Dentistry recommends that children be encouraged to begin drinking from a cup as they approach their first birthday. At nap times or at night, children should not fall asleep with a bottle. It is recommended that nighttime breast-feeding be avoided after the first primary (baby) teeth begin to erupt. Drinking juice or other sugary drinks from a bottle should always be avoided. When such drinks are offered, they should be served in a cup.
