A. Ensure they're drinking lots of liquids so that they stay hydrated. Dress them in lightweight clothing and lower room temperatures. Allow them to rest – in most cases, you shouldn't wake a sleeping child to give them fever medicine.Call your doctor if your child's temperature reaches 102.2 degrees F or higher. Most fevers go away in a couple of days. Call your doctor if the fever lasts four days or more.
