I have found that the ear thermometers really are inaccurate. I'm not sure what kind of thermometers you have but check the batteries in them. Actually, it's cheaper to buy a new one, they are so inexpensive. I'd say just go spend under $10 and get a new digital one. If you are taking a temp. under your child's arm you are supposed to give it 3-4 minutes to get an accurate reading. When my daughter, who is 5 years old, was sick just before Christmas I discovered that our digital no longer worked so I used our old "regular" one (but it's not mercury.) They are the most reliable and never need batteries!
