question: 16 month old baby boy, vomiting after drinking fluids and soft food. Was in the hospital Cardinal Glennon here in St. Louis, Mo. was discharged yesterday. Had rash-hives, found out purple dye in the liquid tylanol was causing that but also had neumonia in both lungs. But was sent home with meds, but now cant keep much down. What are some things a parent can do at home to help his little belly?
