Fever in children is one of the most common reasons parents call their pediatrician — and one of the most misunderstood. Your child wakes up hot, flushed, and miserable. You grab the thermometer and — yep, fever. Now what? For most parents, a fever triggers an immediate sense of alarm. But here's something worth knowing: fever is not the enemy. It is your child's immune system doing exactly what it is supposed to do — fighting off an infection. The temperature itself is rarely the problem. The real question is what is causing it, and whether your child needs to be seen.
