Do you add a degree when taking a newborns temperature under the arm?

No, you don’t add anything. The thermometer will acurately read the underarm temperature.

Normal oral temp is 98.6. Underarm is about a degree lower, rectal temp is about a degree higher.

When you tell the doctor what the baby’s temperature is, just specify where you took it.

You add a degree when taking anyone’s underarm temp, but I believe it’s a degree Fahrenheit that you add, which is smaller than a celcius degree. So no, your baby’s temperature is perfect.
