Pro biotic: Adjust his diet to avoid dairy products, use a pro biotic and if there is blood or mucus in the stool, please see a physician right away. Continue to encourage fluids and crackers/toast, bananas and rice may be helpful. Viral diarrheal illness often is associated with more than 7 days of symptoms. If there are signs of dehydration such as decreased urination, please see your pediatrician.
