Fever 101: When to Call the Doctor and When to Relax

Fever 101 Pediatrics Idaho Falls

It is the scenario every parent dreads. It is 2:00 AM, the wind is howling outside your Idaho Falls home, and your child feels like a little radiator.

You grab the thermometer, and the number confirms your suspicion: Fever.

Panic sets in. Do I rush to the ER? Do I call the doctor? Do I give medicine?

At Bee Happy Pediatrics, we know how scary a fever can be, especially for new parents. But here is the good news: in most cases, a fever is actually a sign that your child’s immune system is doing its job!

To help you navigate those late-night worries, here is our guide on when to treat a fever at home and when to call us.

What Exactly is a "Fever"?

Technically, a fever is a body temperature of 100.4°F (38°C) or higher.

It is important to remember that a fever is not an illness itself; it is a symptom. It is the body’s natural response to fighting off an infection, like a virus or bacteria. Turning up the heat makes it harder for germs to survive.

The "Age Rule": When to Call Us Immediately

The rules for fevers change depending on how old your child is.

1. Newborns (0 to 3 Months) – The "Call Now" Zone

If your baby is under 3 months old and has a rectal temperature of 100.4°F or higher, this is considered a medical emergency.

  • Do not give Tylenol.

  • Do not wait until morning.

  • Call Bee Happy Pediatrics immediately at (208) 497-0680. If it is after hours, seek immediate medical attention. Newborns have developing immune systems, so we need to check them right away.

2. Babies (3 Months to 3 Years)

For this age group, you should call us if:

  • The fever rises above 102.2°F.

  • The fever lasts more than 24 hours.

  • Your child looks surprisingly well but feels hot.

3. Older Children (3 Years +)

For older kids, the number on the thermometer matters less than how they are acting.

  • Are they drinking fluids?

  • Are they making eye contact and playing a little?

  • Are they peeing regularly?

If the answer is yes, you can usually monitor them at home. However, if the fever lasts more than 2 days, give us a call.

Treating Fevers at Home in Idaho Falls

If your child is older than 3 months and is uncomfortable, here is how to help them settle down:

  1. Hydrate, Hydrate, Hydrate: The high desert air in Idaho is already dry, and fevers can cause dehydration quickly. Offer water, breast milk, formula, or electrolyte solutions (like Pedialyte) frequently.

  2. Dress Lightly: It is tempting to bundle them up if they are shivering, but this can trap heat. Dress them in light, breathable pajamas.

  3. Medication:

    • Acetaminophen (Tylenol): Safe for most ages (check dosing with us if under 2 years).

    • Ibuprofen (Motrin/Advil): ONLY for children 6 months and older.

    • Note: Never give Aspirin to children.

Red Flags: When to Call Bee Happy Pediatrics

Regardless of age, call us or seek care if your child has a fever AND:

  • Has trouble breathing or is working hard to breathe.

  • Has a stiff neck or severe headache.

  • Has a rash that looks like purple spots.

  • Is extremely irritable or cannot be consoled.

  • Signs of dehydration (no wet diapers for 8+ hours, dry mouth, no tears when crying).
