Fever in Children: When Should You Worry?

Kara Murphy
Feb. 15, 2018

Fever in children, while scary for parents, is a healthy sign the body is fighting infection, doctors say. Here's what you need to know.

That number on the thermometer keeps climbing. Your child's a wreck -- you even more so. Do you give him more Tylenol? A cool bath? Or is it time to call the doctor?

Take a deep breath, says pediatrician Dr. Barton D. Schmitt, the author of "My Child Is Sick" and creator of KidsDoc, the American Academy of Pediatrics' iPhone app for parents. Fever in children is scary, but it's actually a positive sign that the body is fighting back, he says. Fever is "showing your immune system is turned on, and the body is working to overcome the infection," he says. "If you have an infection, you want to have a fever."

Here's everything you need to know about treating fevers in children:


What Should You Do If a Child Has a Fever?

"I tell parents not to pay as much attention to the fever as to the child and the symptoms," says Dr. David Wolfson, the medical director of Children's Community Pediatrics, an affiliate of Children's Hospital of Pittsburgh of UPMC. "It's much more important to understand why your child has a fever than to worry about the fever itself."

Dr. Schmitt agrees. "Don't look at the thermometer. Look at your child," he says. "I've seen serious infections with just low-grade fevers that needed immediate medical attention. But I've also seen viruses with 105 degree temperatures that didn't need a doctor intervention."

 

How Should You Monitor His Temperature?

Take your child's temperature as much as makes you feel comfortable. You don't need to take a temperature on a set schedule, and don't wake a sleeping child, Dr. Schmitt says.

The American Academy of Pediatrics (AAP) recommends always using a digital thermometer, and taking a temperature rectally gives the most accurate reading. Any temperature over 100.4 degrees taken rectally is considered a fever. Temperatures can also be taken orally or in a variety of other ways.

 

How Can You Make Your Child More Comfortable?

"It's reasonable to use medication like ibuprofen or acetaminophen if a child isn't feeling well," Dr. Wolfson says. But if a child isn't complaining, reconsider, both he and Dr. Schmitt say.

"When a temperature is between 100 and 102, it shows the body is protecting itself," Dr. Schmitt says. "You shouldn't mess around with Mother Nature." In fact, studies have shown that flu patients whose fevers weren't treated were sick fewer days than those who were treated. However, a fever over 102 should be treated with medicine, Dr. Schmitt says.

What you shouldn't do is put a child with a fever in a cool bath, or, conversely, dress them especially warm to try to "sweat" the fever out of her, both experts say. Those solutions "are probably causing more harm than good," Dr. Wolfson explains. A cold bath could give an already sick child more chills, while making a child warmer could worsen dehydration.

 

When Should You See a Doctor?

The AAP guidelines direct parents to call a doctor right away if your child has a fever and:

  • It rises above 104 degrees repeatedly
  • Looks very ill, is unusually drowsy or is very fussy
  • Has been in a very hot place (such as an overheated car)
  • Has symptoms such as a stiff neck, severe headache, sore throat or ear pain, an unexplained rash, or repeated vomiting or diarrhea
  • Has immune system problems
  • Has had a seizure
  • Is younger than 3 months and has a rectal temperature of 100.4F or higher
  • Your child still "acts sick" once his fever is brought down
  • Your child seems to be getting worse
  • The fever persists for more than 24 hours in a child younger than 2 years
  • The fever persists for more than 3 days in a child 2 years of age or older
     

You know your child better than anyone, Dr. Schmitt says. "It's all about looking at your child and how sick he is," he notes. "If you see something that worries you, that seems off -- then immediately call your doctor." Dr. Wolfson agrees. "We always want parents to call if they're worried," he says.

Well i been an over protected single dad for over 10 years my son is almost 11 years old. And thoughout thanks to our Dr's like Dr. Wolfson here and or who make websites like this available, lol i don't know how many nervous breakdowns i would of have. Well here and also i do admit i did listen and pay attention to my loving mother when herself would care for my siblings and i with her (home remedies) both have been a great BIG HELP. thank a million. "Today we are here because all of sudden my son when going to bed had a HEADACHE but assured me himself he was ok.. "Bless his little heart." Nevertheless i made sure i kept watch over him throughout the night and he seemed to be having "mucus " drainage very often plus the NOW severe headache by 2 or 3 AM. Ok then i sorda kinda worried YOU KNOW my worries started when at the beginning like any other CONCERNED PARENT . So i got the "Tylenol" pain & fever( & after reading above i now think i may have done bad. SMH you think after 10 years of being a 24/7 single dad I'D HAVE IT DOWN TO A SCIENCE. ) Please feel free to comment or criticize Anything?? i dont mind it. Lol. "Anyway 3am and he said he had a bad headache plus real hot could not find thermometer so guessing i say his temp was 98.7 or 99.4 between there SO I GAVE HIM HALF OF WHAT IT SAYS TO GIVE HIM. which is 12.5 mL i gave him 7.5mL and rubbed his feet with "medicated vapor rub" "Vicks" with half cup of water HE WAS THIRSTY. Ok that was 3am So he got a little bit of rest but of and on he could not sleep "damm mucus" plus "cough" well about an hour and half after the "Tylenol" he "vomited" and his fever was high a toping 100.4 .."omg jesus" i getting worried its morning he "ATE" only about 1/3 of serving of oatmeal plus i made him a warm lemonade of lime juice with a little bit of 🍯.... Lol i dont know but i think i got carried away here with the "comment" . but we have good news took temp again 2 hours later & its reducing so is his headache ..THOUGH we are not in the clear yet . He will eat a old fashion "chicken noodle" SOUP i will ease up on the "Tylenol" and hope for the BEST. AND WISH ANY OTHER concern parent out there also the "BEST" 🙏👍 ""Oh about the finger near the outlet ......oooihf thats a tough one .. Never actually experienced it before if that was me i am going to be blunt here depending on the age but i am guessing 3 yr olds? I would have to firmly remove him while entertaining him with something BETTER FOR HIM covering up that outlet if persistent than i say smack his or her hand firmly enough SO that they KNOW you mean business. We are in charge but we also want them to feel ....FREE and to love us back not be scared.. Of us. God bless everybody. Good day.
