What kind of thermometer do you use?  

My son, 2 1/2, hates to have his temperature taken. It is impossible to get him to sit still long enough. I use a digital thermometer under his arm, because it is the only way I can hold him since it takes so long.

I tried an ear thermometer, but it doesn't seem to be accurate. I tested it on myself a few times, comparing it to the digital one taking temperature under the arm. The underarm one is consistent, while the ear one varies by as much as 2 degrees from one reading to the next. I was careful to follow the directions closely, and still not consistent.

I heard that the ones you swipe across the forehead are accurate, but they are so expensive. Any recommendations? What kind do you use, and is it accurate? How long does it take to get a reading? Thanks
