Question of the day: should I avoid milk witth my daughter who has diarrhea?
Answer: Maintaining hydration is important and if a child loves milk, she is more likely to drink it than other things, so give it to her. Milk is probably better for her than juice or other sugary drinks like gatorade which pull water into the gut and make diarrhea worse. After a few days of diarrhea some children develop a temporary milk intolerance in which case you will notice that the milk seems to make things worse. In that case avoid the milk or use lactaid milk.
Call the doctor if ther is blood in the stool, fever, vomiting, worsening diarrhea, or lack of urine.
