One of my encounters with Fever
I dread those days when my daycare provider calls me at work. She messages me on a normal day when there is something we need to chat about or she waits for me to get to daycare after work.
But when she calls me at the hospital (I work for the community hospital in case you are new here, by the way.) in the middle of the day…
That is a different story.
Today, that dreaded call came about. My colleague (who is also a good friend) picked up the phone, handed it over to me, mumbled my daycare provider’s name and everything just turned gloomy.
With a heavy heart, I took the call. I knew what she was going to say. “Donna, Baby V’s temperature is at 102.”
I replied with the calmest tone I could muster, “Okay. I will be there as soon as I can.”
What we always hear from doctors about fever
We always hear from our doctors that a fever is not a bad thing. It is just one sign that tells us the body is waging a war against infection.
That doesn’t make it any better at all.
As mothers, that statement always fails to give us comfort. We still stress ourselves out every time our little ones are sick and nothing in the world can stop that from happening.
So tonight, I decided to write something that will help us know more about this common sign of illness.
I hope this will shed some light on fever in babies and toddlers as a whole.
What is a fever?
A fever is an abnormal increase in body temperature often triggered by a bacterial or viral infection.
It is one of the most common signs that tell us that the body is fighting a bug or other illnesses.
Signs of fever in babies and toddlers
Appear flushed
You can usually tell that your baby or toddler is hot just by looking at them because their cheeks will appear red.
Though sometimes it won’t mean he/she is febrile, appearing flushed can be a sign that your baby or toddler has a fever.
Hot to the touch
Although feeling your baby or toddler’s forehead, back or tummy can tell you that he/she is febrile, you will need to check his/her temperature using a thermometer to accurately tell that he/she has a fever.
Weakness or lack of energy
Most babies or toddlers won’t appear docile when sick. It is not a cause for concern when they still enjoy playtime.
However, when they seem weak, groggy, and seem to lack energy that is a bit alarming. Watch out for this sign closely. You will need to see the doctor if it continues.
Irritability
Little kids when under the weather can’t express how bad they are feeling. As a result of that, they get frustrated leading them to be cranky.
Poor appetite
Just like us adults, our babies and toddlers lose their appetite when ill. You have to make sure that they get enough fluids when this happens to avoid dehydration.
Poor sleep
Imagine yourself battling a fever. Then imagine battling a fever and being helpless.
What can little babies do to put themselves to sleep on their own when they can’t even calm themselves down and be comfy?
Nothing… Nil… Zero… None… Am I right?
It is so hard to sleep when you feel so hot and uncomfortable even for adults like us.

What is the average body temperature of a baby?
A baby’s normal body temperature is within the range of 36.3°C (97.4°F) to 37.6°C (99.6°F). That brings us to an average normal temperature of 37°C (98.6°F).
A temperature that falls above that threshold indicates fever.
Keep in mind that each person’s body temperature is different. Your baby’s typical body temperature may vary depending on the time of day, activity level, or environment.
What is considered a fever in a newborn or a toddler?
If a baby under three months old has a rectal temperature of 38°C (100.4°F), you must see a doctor at all costs since this particular age group is at a higher risk for an even more severe complication.
For older babies, a temperature of over 102.2°F (39°C) is considered a fever and should be reported to the child’s healthcare provider.
Fever Temperature Chart for Newborns and Toddlers
| Kid’s Age | Thermometer to Use | Temperature Considered a Fever | Important Reminder |
|---|---|---|---|
| 0 to 2 years | Rectal Armpit | 100.4°F (38°C) 99°F (37.22°C) | If a baby under 3 months old has a rectal temperature of 38°C (100.4°F), you must call the doctor right away because this age group is at a higher risk for a more serious complication. |
| 2 to 5 years | Rectal Ear Armpit | 100.4°F (38°C) 100.4°F (38°C) 99°F (37.22°C) | A kid with a fever over 40°C (104°F) that doesn’t go away even when taking fever-reducing medication must see a doctor at all costs. |
It is important to note that the most accurate temperature readings depend on the age of the child.
I also need to mention that whatever thermometer you use for a specific temperature-taking method should only be used for that specific method.
What you use for the mouth should never be used for the armpit. You must get the gist here.
Ways to Take your Baby or Toddler’s Temperature
In the mouth
The accuracy of an oral reading can’t be dependable after one eats or drinks. For a more valid reading, take oral temperature at least 5-10 minutes after eating or drinking.
Under the arm
More active little children (toddlers) are less cooperative, so it is harder to take a rectal temperature from them. Taking the temperature in the armpit is a better way to go, though it is a little less accurate.
In the bottom (rectum)
The American Association of Pediatrics recommends that temperature checks should only be done rectally for at least the first year of a baby’s life (though up to three is best).
This rectal thermometer provides a 10-second quick read and has a parent-proof stopper that keeps you from inserting it too far. It also has a large display with an LED light, which makes nighttime temperature checks easier and worry-free. Plus, it’s BPA-free, latex-free, and water-resistant. It comes with a case too!
By ear (tympanic)
Ear temperature taking is another way. Even though it’s trickier to execute, I prefer to take my toddlers’ temperatures by ear.
Please be reminded that this method is not advisable for neonates and older infants because of their narrow ear canals.
Through the temples of the head
Another reliable way to check your baby’s temperature is through their forehead.
This ergonomically designed handheld thermometer is highly reliable and precise! It can measure human temperature accurately.
The best part? You don’t need any contact!
What are some causes of fever in babies and toddlers?
Upper and Lower Respiratory Tract Infections
Common Respiratory Infections
- common cold
- flu
- bronchitis
- croup
- pneumonia
- Strep throat
Ear Infections
An ear infection doesn’t always come with a fever. It is always best to watch out for other signs like earaches, ear tugging and ear drainage.
Urinary Tract Infections
UTIs are difficult to recognize in little children, especially because they still can’t talk or express themselves.
Having a fever is one sign to watch out for if you don’t notice any other symptom.
Vaccinations
Though this may not always be the case, vaccinations can trigger a fever in babies and toddlers.
Getting something foreign to your body can sometimes shock your system and that is just a normal thing.
Heat Exhaustion
When dressing up our little ones, we have to consider the external temperature. Don them in the right amount of clothing to avoid heat exhaustion.
More Serious Illnesses
Very rarely can we encounter such a thing. However, there is no harm in assuring that our babies are healthy and normal.

What to do if your baby has a fever?
Try to give your baby or toddler some antipyretics (or in layman’s terms, fever reducers).
Depending on your baby’s age, over-the-counter fever reducers such as Tylenol and Motrin can help.
Never forget to consult your doctor or your pharmacist to avoid administering the wrong dosage.
IMPORTANT: Don’t use acetaminophen in babies under 12 weeks unless prescribed by a doctor. Fevers in the first 12 weeks of life should be documented in a healthcare setting.
Dress your baby lightly.
Relaxed pants paired with a breezy long-sleeved top are a good choice when home. At bedtime or naptime, cover your baby or toddler with a light sheet instead of a heavy blanket.
Remember to always check the house’s temperature. A good temperature for an average-sized room is between 72°F to 74°F.
Increase your baby’s fluid intake.
Make sure your children have enough to drink. Increasing your baby’s fluid intake can help prevent dehydration caused by loss of appetite.
Dehydration is a scary thing. We must avoid it at all costs.
Let your baby take plenty of rest.
Allow your baby to rest. Everything is fascinating to babies and toddlers. They may be sick, but they have the curiosity of a cat and will stay active regardless.
Let them take the much needed rest.
Keep your baby home from child care.
The Centers for Disease Control and Prevention and the American Academy of Pediatrics advise that you keep your baby home from daycare (or Preschool, if they ever go to one) when they are sick.
Keep them home until at least 24 hours after the fever is gone or any signs of a fever (without the use of a fever-reducing medicine).
When to call your baby’s doctor and when to worry about your baby’s fever
The exact temperature that prompts a trip to the doctor is determined by your child’s age, the illness, and whether or not other symptoms exist in addition to the fever.
If a baby under three months old has a rectal temperature of 38°C (100.4°F), you must see a doctor at all costs since this particular age group is at a higher risk for an even more severe complication.
In addition, seek emergency care when a fever in babies and toddlers comes with other alarming symptoms such as:
- rash
- pain
- vomiting
- diarrhea
- trouble breathing
- irritability
- inactivity
- inconsolable crying
- fever that lasts more than 24 hours and spikes up to 40°C (104°F) even when taking fever-reducing medication
Pay attention to what your intuition tells you. As parents, we know our children better, and when we believe they need to see a doctor, we are more than likely correct.
Important Reminder about Fever in Babies and Toddlers
Remember that fevers are the body’s immune response to infection. It indicates that the body’s immune system is functioning well.
It is, however, an important indicator of illness. If you have any further concerns, please contact your child’s healthcare provider.
My Question for You
Did you ever experience getting those dreaded calls from your babysitters telling you your baby or your toddler is running a fever?
Those never get old for me. They still give me the frights.
How about you? How do you feel about them?
Please leave your responses below, and if you have time, please share this essential guide to fevers in babies with your family and friends!
Thank you for stopping by. Kindly read up on my other baby-related subjects and share them with your friends.
Tell me what you think as well. If you want to shoot me an email, please do so.
Talk to you soon,
I work in childcare and I wish more parents would take your advice and let their babies rest at home when they have a fever. I know parents have to work, but their babies are miserable. Then the illness spreads like wildfire and I end up bringing it home to my daughter. It’s really frustrating. My mom takes care of her and I dread those texts even though I don’t usually have to come home. I still want to though because I know she wants me with her when she’s sick. Thanks for sharing this important information about fevers in babies and toddlers.
Thank you so much for emphasizing the importance of resting at home when babies and toddlers have fevers, Darcey. As a medical practitioner, it is one of the things I want parents to realize. After all, our littles need our tender loving care when they are sick.
This is very helpful info! Thanks! We recently had a run in with an extreme issue with toddler fevers. My 16 month old spiked a fever quickly and ended up having a febrile seizure. He also stopped breathing and turned blue. We had to call 911 and take an ambulance to the hospital. Scariest day of my life! I definitely learned more about fevers that day. They said that febrile seizures themselves don’t cause damage but could have other issues if not careful. I am so glad my son is okay but now I am much more aware when he gets a fever.
Oh no! I could only imagine how you felt when your 16-month old was seizing. My mom had once experienced a febrile seizure with my niece (as my parents are taking care of my nephews and nieces) and she was scared to death. (To think she is a nurse herself!) I guess it is really different when it happens to you. However, I still believe that if ever in the future it happens again, at least we are armed with enough know-how on fever in babies and toddlers that will generally help us in more ways than one. Thank you for sharing, Laura.
