My son is 5 years old and having a running stomach since sunday,he dont want to eat any food i've tried giving him banana and also tried pactrolyte medicine but not helping at all. can any advise what's the best thing i can do?

Ask him...: The key is to get nutrients back into his body, especially proteins. So ask him what he wants to eat. You only need to avoid high sugar foods and high fiber foods as both of these could potentially make his diarrhea worse. Good foods kids like - peanut butter, almond milk, scrambled eggs. Easy to digest complex carbs - rice, whole wheat toast. Drink water or almond milk.
