Understanding Fevers in Children

What exactly does it mean to have a fever for a child? There is a part of the brain called the hypothalamus. It understands what temperature the body should be and helps to send signals to regulate temperature. For most, people a normal temperature is 98.6°

For most people, kids included, body temperature will vary depending on activity level and even time of day. If the body is trying to ward off an infection or illness, the hypothalamus will change the body’s temperature and a fever will present itself. 

This is a sign from the body that something else is happening in the body. Here are the temperatures to be concerned about in children:

  • 100.4° or higher if taken by rectal, forehead or ear
  • 100° or higher if taken by mouth
  • 99° or higher from under the armpit

To get an accurate reading, experts don’t believe ear temperatures are accurate before 6 months of age.
