🌡️ What Is a Fever?
A fever is your child’s natural response to infection. It raises body temperature to help fight off viruses and bacteria. Most fevers are caused by common colds or viral illnesses — and they’re not always dangerous.
📊 What Counts as a Fever?
| Method | Fever |
|---|
| Rectal | ≥ 100.4°F (38°C) |
| Oral | ≥ 100.0°F (37.8°C) |
| Forehead | ≥ 100.4°F (38°C) |
| Underarm | ≥ 99.0°F (37.2°C) |
Tip: Use rectal readings for infants under 1 year.
🦠 What Causes Fever?
- Viral infections (cold, flu, RSV, COVID-19)
- Bacterial infections (ear infection, UTI, strep)
- Post-vaccine response (mild & short)
- Overheating — rare, not illness-related
⚠️ When Is Fever Concerning?
- Under 3 months old with ≥ 100.4°F
- Fever lasting more than 72 hours
- Not drinking fluids, signs of dehydration
- Very sleepy, floppy, or hard to wake
- Blue lips, trouble breathing, or seizure
💊 Do I Need to Treat the Fever?
If your child is drinking, playing, and fairly normal, it’s okay to watch and wait.
Use fever medicine if:
- Your child is uncomfortable or in pain
- Fever is over 102°F and interfering with rest
Options: Acetaminophen (2+ months) or Ibuprofen (6+ months)
👀 What Matters Most: Behavior
| Normal | Concerning |
|---|
| Drinking well | Not drinking/peeing |
| Alert, responsive | Lethargic or floppy |
| Fever lowers with meds | Stays high after meds |
| Improving | Worsening after 3 days |
Trust your instincts. If your child seems off, check in with your provider.
Fever Myths vs. Facts
🤒 Fever Myths vs. Facts
A fever over 100°F is dangerous
Fever under 105°F is usually safe — it’s a natural immune response.
You must treat every fever with medicine
Only treat if your child is uncomfortable or not drinking — not just based on temperature.
Fevers always mean a bacterial infection
Most fevers in children are caused by viruses, not bacteria.
High fevers cause brain damage
The brain is protected — fever itself doesn’t cause brain damage.
You should wake your child to give fever medicine
Let them sleep — rest helps recovery more than reducing the fever.
Bundle them up to sweat out a fever
Dress them lightly — overheating can make a fever worse.
You can’t use ibuprofen and acetaminophen together
You can alternate them if advised by your provider. Just track doses carefully.
If the fever doesn’t go away in 24 hours, it’s serious
Viral fevers can last 2–3 days. Call your provider if it lasts beyond 72 hours.
The higher the fever, the worse the illness
The number doesn’t always match severity — behavior matters more.
Febrile seizures mean epilepsy
Febrile seizures are common and usually harmless in young children.
