Safety 1St Thermometer
Hello, I have the safety 1st thermometer for the arm, rectum and mouth...The instructions came with the different temperatures for each option. So what measures in the mouth is different from under the arm. Well I cannot find it. So I was wondering if anyone had that information. Also, I use the one for under the arm and I am not sure if it is accurate. Any thoughts/advice?? Thanks so much:)
