Electronic thermometer giving different readings between forehead and ear. Which is accurate?

[Ohanythingwilldo]

I have an electronic thermometer and if I zap DS forehead I get a reading of around 39 but if I do his ear it is 37. Does anyone know which reading is more accurate?

An under arm one is more accurate. Do you have one?

I have always found the ear ones give widely ranging temperatures. Try the ear again / the other ear & see.

The ear ones are supposed to be much more accurate than forehead ones. Does he feel like he's got a high temp?
