I hear fevers can be good for you if they are low but what is high? My son currently has a fever of 100.0 under his arm he's 17 months old should I give him something? He doesn't seem to be uncomfortable. I'm taking him in later today or tomorrow if his fever doesn't go away. Luke warm baths, lots of sleep, soups are in our routine right now is there anything else I can do to make him feel better? I am also giving him tylenol and motrin when he seems to be feeling bad but he's acting fine right now so I'm just asking.
