Guidelines for Treating Stomach Flu in Babies

My son is 11 months old and recently had the stomach flu. He vomited and had diarrhea for four days. His formula made the diarrhea worse. I switched to Pedialyte and it got a little better. He is fine now. What should I do if he gets this again? Is it better to give him just Pedialyte and no formula since he is eating solids? Or should I continue giving him formula even though it makes the diarrhea worse?
