My 10 month old has had a fever of 102.2 (taken under her arm) for past 2 hours even after Tylenol it is still 101.7. She will hardly eat or drink, very congested, constipated and shivering even though her body is burning up. She can barely hold her eyes open and drowsy but restless. What can I do to make her comfortable and how long do I allow the tylenol to to take affect before going to the E.R..
