Fever. A common question for many parents is, “What is considered a fever?” Fever in children can be scary, but just because there is a fever does not always mean there is cause for alarm. Normal body temperature is considered 98.6 F (37 C). In the world of pediatrics, a fever is considered 100.4 F (38 C) per the Centers for Disease Control and Prevention (CDC). 

A fever helps the body by stimulating the immune system to fight the infection. Other common reasons children will develop a fever are overdressing, immunizations and occasionally teething, although in these cases the fever is typically less than 100 F. 

If your child is under three months old and has a fever of 100.4 F or higher, you should seek medical attention.

A child with a fever likely does not have a serious issue if they are still interested in playing, drinking adequately, are alert, have normal skin color and look well as the fever decreases. Children may not eat as well when they have a fever. 

Signs of a fever include flushed cheeks, chills or sweating, feeling warm to the touch and decreased activity. 

The best way to take a child’s temperature depends on their age. For children younger than three, a rectal temperature is the most accurate. If you do not feel comfortable taking a rectal temperature, an axillary (under the arm) thermometer is the next best option. 

When children are old enough and can cooperate, an oral thermometer works best. Although it is simple, a temporal (forehead) or tympanic (in the ear) thermometer is not as accurate as other temperature-taking options. 

Treating a fever can be as simple as letting the child rest and encouraging fluids. Acetaminophen and ibuprofen are options for treating a fever at home as well. Always follow the package directions for how much to give and how often. If you don't know the recommended dose or your child is younger than two years old, call your child’s primary care provider to find out what to use and how much to give.
