Hi Cherie,

I have also heard & Read in medical books that charting with an ear thermometer was not accurate if you are trying to chart for O.

I would stick to the digital ones, im using one at the moment to chart my temps and its pretty accurate, i do have a ear one which i use on my daughter and even then i get different temps in different ears because it depends on the position you put in the ear, i wouldn't use them for charting!

Hope that helps you any!
