I am a pediatric nurse and mom of 4, so let me see if I have any pearls of wisdom. A fever is the body's way of fighting infection. That infection could be viral or bacterial. Frequently, young children will get a fever that is not accompanied by other symptoms and a couple of days later will breakout in a fine, red, pinpoint rash. This is a virus called roseola. Teething will not cause a fever, although it can decrease the immune system's ability to fight infection, thereby resulting in illnesses concomitant with teething. If your angel is feeling ok with the fever and it isn't above 103, don't bother with Tyl/Motrin. If she is having trouble sleeping or seems cranky, dose her appropriately. Watch for signs or symptoms of infection such as poor appetite, excessive fussing, poor sleeping, green nasal discharge, cough etc... Hang in there! Remember to wash hands very well to prevent spread of infections!
