Tips to Take Your Child's Temperature
How often do you need to check? That depends on the situation. Ask your pediatrician. Usually, you don't need to take your child's temperature obsessively or wake him up if he's sleeping peacefully. But you should do it if his energy seems low.
Which thermometer is best for kids? Digital ones are best. They can be used in his mouth, rectally, or under the arm.
For young children, a rectal temperature is most accurate. If your kids are age 4 to 5 or older, you can probably get a good reading with a thermometer in the mouth. Under the arm is less reliable but it's easier to do. Remember to add a degree to an underarm reading to get a more accurate number.
