Many of the "clear liquids" used by parents or recommended by doctors in the past are no longer considered appropriate for kids with diarrhea. Don't offer: plain water, soda, ginger ale, tea, fruit juice, gelatin desserts, chicken broth, or sports drinks. These don't have the right mix of sugar and salts and can even make diarrhea worse. Infants and small children should never be rehydrated with water alone because it doesn't contain adequate amounts of sodium, potassium, and other important minerals and nutrients.
