A fever is often a sign that the body is fighting an infection. For children, a fever can be concerning, but it is not always dangerous. Ensure they stay hydrated by offering plenty of fluids. Over-the-counter medications like acetaminophen or ibuprofen can help reduce fever, but always consult your pediatrician before administering any medication. If the fever persists for more than a couple of days or is very high, seek medical advice.
