Fever in Children: When to Watch, When to Call, and When It Is an Emergency
Few things make parents worry faster than seeing a high number on the thermometer. But the good news is that fever itself is usually not dangerous. In most cases, it is simply the body’s way of fighting an infection.
So, when should you watch your child at home? When should you call the pediatrician? And when is it time to head straight to the ER?
Here’s our simple Mama Medics guide.
First Things First: What Counts as a Fever?
A fever is generally a temperature of 100.4°F (38°C) or higher.
How you measure the temperature matters. Rectal temperatures are the most accurate for infants, while oral, axillary (under the arm), and other methods may be used for older children depending on their age and what your pediatrician recommends.
And remember: the number on the thermometer is only part of the story.
A child with a 103°F fever who is drinking, talking, playing intermittently, and breathing comfortably may be less concerning than a child with a lower fever who is unusually sleepy, struggling to breathe, or not drinking.
When You Can Watch at Home
Most childhood fevers are caused by common viral infections and can be managed at home.
If your child is:
• Drinking fluids
• Urinating regularly
• Breathing comfortably
• Alert and responding normally
• Having periods where they are comfortable or playful
• Generally acting like themselves between fevers
then it is usually reasonable to monitor them at home.
What Can You Do?
Focus less on getting the temperature back to a "normal" number and more on keeping your child comfortable and hydrated.
Offer plenty of fluids and allow your child to rest. Dress them comfortably rather than bundling them up.
If your child is uncomfortable, fever-reducing medications such as acetaminophen (Tylenol) or ibuprofen (Motrin) may be appropriate depending on their age and medical history. Never give aspirin to children’ please ask your pediatrician if you're unsure which medication or dose is appropriate.
When Should You Call Your Pediatrician?
Give your pediatrician a call if:
• Your child has a fever that is lasting several days
• Your child is getting worse rather than better
• They are drinking very little or urinating much less than usual
• They have persistent vomiting or diarrhea
• They have significant pain, such as severe ear, abdominal, or throat pain
• They develop a concerning rash
• They have a weakened immune system or significant underlying medical condition
• You simply feel that something isn't right
Trust your instincts. You know your child better than anyone.
And if you're sitting at home thinking, "I don't know if this is something I should worry about," that's exactly what your pediatrician is there for.
When Is a Fever an Emergency?
Some symptoms require urgent evaluation.
Seek emergency care if your child has a fever along with:
• Difficulty breathing or working hard to breathe
• Blue, gray, or unusually pale lips or skin
• Severe lethargy or difficulty waking
• A seizure, especially a first seizure
• A stiff neck with severe headache or altered mental status
• Signs of severe dehydration
• A rapidly spreading or purple/petechial rash, particularly if your child appears ill
• Severe or worsening pain
• Significant confusion or a major change in behavior
And One Important Exception: Babies Under 3 Months
For babies younger than 3 months, a temperature of 100.4°F (38°C) or higher is considered an emergency and requires prompt medical evaluation, even if your baby otherwise looks well.
Don't wait to see if the fever comes down on its own. Call your pediatrician or seek urgent medical evaluation.
Remember: Fever Is a Symptom, Not the Enemy
A fever can look scary, but the number itself isn't usually what determines how sick your child is.
Instead, ask yourself:
How is my child breathing?
Are they drinking?
Are they peeing?
Are they alert and responsive?
Do they have periods where they seem like themselves?
Is something about their behavior worrying me?
Those answers can tell you much more than the thermometer alone.
And if you're still unsure?
Call your pediatrician.
