How much is needed for measuring a baby's body temperature in the armpit?

Patient's question:

No

Doctor's answer:

Hello, no need to add. Measuring body temperature generally uses three parts, namely the mouth, armpit, and rectum. Normal body temperature at the rectum is between 36.5℃ and 37.5℃; at the mouth is between 36.2℃ and 37.3℃; at the armpit is between 35.9℃ and 37.2℃. After measurement, if it exceeds the normal range by more than 0.5℃, it is called a fever. If it does not exceed 38℃, it is called low-grade fever, and if it exceeds 39℃, it is called high fever.
