Why should you avoid giving a bottle of milk or sugary liquid to an infant to go to sleep?

• A. Obesity
• B. Tooth decay
• C. Allergic reaction
• D. Diarrhea

Answer: (B)

The key idea is that giving a bottle of milk or a sugary liquid to help an infant fall asleep creates prolonged exposure of teeth to sugars, which promotes tooth decay. When a baby sleeps, saliva production drops, so sugars from the liquid stay on the teeth longer and aren’t washed away. Bacteria in the mouth feed on those sugars and produce acids that demineralize enamel, leading to early childhood caries. Milk contains lactose, a fermentable sugar, and while formula or breast milk are common, the same principle applies: nighttime bottle feeding keeps sugars in contact with teeth during a period of low saliva flow, increasing the risk of decay. Other options aren’t addressing this specific mechanism. Obesity is a broader risk from excess sugar intake but isn’t the immediate dental issue here; an allergic reaction or diarrhea isn’t the typical outcome of a bedtime bottle with milk unless there’s an underlying intolerance, which is less about the sleep cue and more about individual sensitivity. Practical approach includes avoiding the bedtime bottle, offering water if the child is thirsty, and brushing or wiping the child’s teeth after feeds. Gradually weaning off the bottle to a cup can help prevent this pattern.
