Hi, My 4 year old has fever, chills, sluggishness (from time to time), vomited twice in 12 hours, and urinated on himself after a nap. Tylenol helped to get fever down, gave him pedialite with apple juice throughout the day, ate a bowl of chicken noodle soup and an icecream cup. Is there anything else I could give him to help him? When should I start to panic?
