My son had a fever for about 24 hours, the last spike of which was around 5:00 AM. He was remarking that sounds (like the fan in my room, which was running when he came in this morning) were too loud and it was quite upsetting for him. I gave him Motrin, put him to bed, and he has been fine all day. Now, he doesn t have an elevated temp but is saying that the fan in his room (which he usually cannot sleep without--we love our white noise) is too loud. Do children experience a heightened sense of sound when they are feverish and, if so, does this heightened sense go away when the feve abates?
