How do you prevent baby bottle tooth decay?
Bottles are only for breast milk, formula and water. If the child has diarrhea, it is acceptable to give him electrolyte drinks through a bottle. When training the child to use a sippy-cup, dilute juice with an equal amount of water to reduce sugar, but only use it in the cup, never the bottle.
