Diagnosis Emily

Emily has spent the last two days battling a fever. On our snow-day, Tuesday, she work up really cuddly which is unusual. She ate a good breakfast, but from then on out all she wanted was to rock with her "ba ba" (paci) and her blanket. I think we spent 6 hours in the recliner. Today she woke up and seemed back to her normal self. We had an ear re-check at the pediatrician at 9:00 am, we went to story time at the library and ran some errands. After lunch Emily went down for her nap, she only slept 40 minutes, which it atypical for her. The next five hours of the day were spent like Tuesday. Her temperature wavers from 101.3 to 103.2 F. Tylenol does not seem to be reducing the fever or making things more bearable for her. Besides the fever she seems to be symptom free. Any diagnosis for me?
