When your child spikes a fever, it can feel unsettling — especially in middle of the night. Fevers are one of the most common reasons parents call the doctor, but not every fever means an emergency. Knowing what’s normal, how to keep your child comfortable, and when to seek medical help can make a world of difference.
As a pediatric nurse, I want you to feel confident navigating fevers — not panicked. Here’s what every parent should know.
What Counts as a Fever?
- A fever is a body temperature of 100.4°F (38°C) or higher when measured with a reliable thermometer.
- Normal body temperature can vary slightly, but generally falls between 97–100°F (36.1–37.8°C).
- Fevers are the body’s natural defense against infection — they help fight off viruses and bacteria.
At-Home Comfort Strategies
While a fever itself isn’t dangerous in most children, it can make your child feel pretty miserable. These tips can help ease discomfort:
- Focus on hydration. Offer water, electrolyte solutions, or broth frequently.
- Dress lightly. Avoid bundling your child — light pajamas and breathable blankets are best.
- Encourage rest. Let them nap or relax without pressure to be active.
- Cool environment. Keep the room comfortably cool with a fan or open window if needed.
- Medication if needed. Use acetaminophen (Tylenol) or ibuprofen (Motrin/Advil) for discomfort or fussiness, not just the number on the thermometer. Always follow age/weight dosing guidelines. (Never give aspirin to children due to the risk of Reye’s syndrome.)
When to Call the Doctor
Most fevers will pass on their own. But sometimes a fever signals that your child needs medical attention. Call your provider if your child has:
- Any fever in a baby under 3 months old (always call right away)
- A fever over 104°F (40°C) at any age
- A fever that lasts more than 3 days
- Breathing difficulties, persistent vomiting, stiff neck, seizures, or extreme sleepiness
- Signs of dehydration (very few wet diapers, dry mouth, no tears when crying)
Trust your instincts — if your child seems “off” in a way that concerns you, it’s always okay to check in with your pediatrician.
