Fever Friend or Foe? Understanding and Managing Your Child’s Fever

As parents, seeing our child uncomfortable with a fever can be worrying. That flushed face, the unusual quietness, or the fussiness – it’s natural to feel concerned. At Chantilly Pediatrics, we understand your worries, and we’re here to help you navigate those feverish moments with confidence.

Fever itself isn’t an illness but rather a sign that your child’s body is fighting off an infection or another issue. Think of it as the body’s natural defense mechanism kicking into high gear! While often a simple indicator of a common cold or virus, it’s important to know how to manage a fever and when it might signal something more serious.

What Exactly is a Fever?

A fever is a temporary increase in body temperature, typically above the normal range. Generally, for children, a rectal temperature of $100. 4^{\circ} F$ ( $3 8^{\circ} C$ ) or higher is considered a fever. Oral and axillary (armpit) temperatures that are slightly lower may also indicate a fever, but rectal temperatures are the most accurate for infants and young children.

Taking an Accurate Temperature: The First Step

Knowing how to take your child’s temperature correctly is key. Here are a few common methods:

Rectal: Recommended for babies and toddlers up to age 3 for the most accurate reading.
Oral: Suitable for children aged 4-5 and older who can hold the thermometer under their tongue properly.
Axillary (Armpit): Less accurate but can be used for a quick check at any age. Generally, an armpit temperature of $99. 4^{\circ} F$ ( $37. 4^{\circ} C$ ) or higher is considered a fever.
Tympanic (Ear): Can be used for children 6 months and older, but technique is important for accuracy.
Temporal Artery (Forehead): Convenient and quick, suitable for all ages, but follow manufacturer instructions carefully.

Always use a digital thermometer, as mercury thermometers are no longer recommended due to safety concerns.

When is a Fever a Concern? Know When to Call Us.

While most fevers are not dangerous, there are times when you should call Chantilly Pediatrics. Here are some general guidelines:

Infants under 3 months: Any fever of $100. 4^{\circ} F$ ( $3 8^{\circ} C$ ) or higher taken rectally needs immediate medical attention.
Children 3 months to 3 years: A fever of $102. 2^{\circ} F$ ( $3 9^{\circ} C$ ) or higher, or a lower fever that lasts for more than three days or is accompanied by concerning symptoms.
Older Children and Teens: High fevers (often above $10 3^{\circ} F$ or $39. 4^{\circ} C$ ) that don’t respond to fever-reducing medication, or any fever lasting more than 3-5 days.

Regardless of the number on the thermometer, call us if your child with a fever also:

Looks very ill, is unusually drowsy, or is very fussy/irritable
Has difficulty breathing or is breathing much faster than normal
Shows signs of dehydration (dry mouth, no tears, significantly fewer wet diapers or trips to the bathroom)
Has a stiff neck, severe headache, or a new skin rash (especially one that looks like small bruises)
Has a seizure
Has a known immune system problem or is taking immunosuppressant medication
Complains of specific pain (like ear pain or sore throat) that is worsening
If you’re simply worried – your parental intuition is important!

Common Causes of Fever in Children

Most fevers in children are caused by viral infections, such as:

Common cold
Flu (influenza)
Roseola
Chickenpox
Hand, foot, and mouth disease

Bacterial infections can also cause fevers and may require antibiotics. These include:

Ear infections
Strep throat
Pneumonia
Urinary tract infections

Sometimes, overdressing (especially in newborns) or immunizations can cause a temporary, mild rise in temperature.

Making Your Child Comfortable at Home

If your child has a fever but is otherwise playful and drinking fluids, your main goal is to keep them comfortable. Here are some things you can do:

Light Clothing: Dress your child in light, breathable clothing. Avoid overdressing or heavy blankets, as this can trap heat.
Fluids, Fluids, Fluids: Offer plenty of fluids like water, diluted juice, electrolyte solutions (like Pedialyte), or ice pops to prevent dehydration.
Rest: Encourage quiet play and rest.
Lukewarm Sponge Bath (Use with Caution): A lukewarm (not cold) sponge bath may help bring the temperature down if your child is very uncomfortable. Avoid cold water or alcohol rubs, as these can cause shivering and actually raise the core body temperature.
Medication (If Needed):
- You can consider using fever-reducing medications like acetaminophen (Tylenol) or ibuprofen (Advil, Motrin) if your child is uncomfortable or the fever is high.
- Always use the correct dosage based on your child’s current weight.
- Ibuprofen should only be given to children 6 months of age and older.
- Aspirin should never be given to children or teenagers due to the risk of Reye’s syndrome.
- It’s often not necessary to treat a low-grade fever if your child is otherwise comfortable and playing. The fever is helping their body fight the infection.

A Note on Fever Myths

Myth: All high fevers cause brain damage. Fact: Fevers caused by infection rarely go high enough to cause brain damage. This is typically only a concern with extreme environmental temperatures (like being left in a hot car) or very rare conditions.
Myth: The height of the fever indicates the severity of the illness. Fact: How your child looks and acts is often more important than the exact number on the thermometer (especially for children over 3 months old).
