To reduce a fever in a toddler, WebMD recommends increasing fluid intake, administering acetaminophen or ibuprofen, and calling the pediatrician if the fever lasts longer than 24 to 48 hours or is accompanied by a rash, vomiting or a headache. The Mayo Clinic recommends ibuprofen only for children over the age of 6 months, and counsels that labels should be carefully read to determine the proper dosage.
Medication isn't required for a fever of up to 102 F in children over the age of 3 months, according to the Mayo Clinic. As noted by WebMD, a fever is the body's way of fighting an infection, so it's important to let the body do its work. Both WebMD and the Mayo Clinic warn that children under the age of 18 should never be given aspirin because of the risk of Reye's Syndrome, which is a serious condition.
The best way to take a child's temperature, according to WebMD, depends on the child's age. In general, digital thermometers are safer and easier to use than glass thermometers. For babies and toddlers, rectal thermometers are the most accurate and easiest to use. For children between the ages of 2 and 5, ear or under-arm thermometers work well. Although they may not be as accurate as a rectal thermometer, they will give a general idea about the child's temperature. Children 5 and older can use an oral digital thermometer.
