find out what temperature they consider a fever. Some providers say that a child is
considered to have a fever if their temperature is 99.5°F (37.5°C) or higher by mouth,
99°F (37.2°C) or higher in the armpit, or 100.4°F (38°C) or higher in the rectum.

use a thermometer that's put in the ear (tympanic) or held near the forehead (temporal), ask your provider what temperature means a fever on that device. Ask your child's
provider for a handout so you'll remember the temperature numbers when your child es
ill.
