Few things unsettle a parent like a hand on a warm forehead at bedtime. The thermometer climbs, and the questions start. Is this normal? Is it high enough to worry? Do I wait, or do I call? If you have ever stood in a dark hallway running through every possibility, you are not alone, and you are not overreacting.
The good news is that most fevers are the body doing exactly what it should. This guide explains what a fever really is, how to know when it needs attention, and simple ways to help your child feel better. It is part of our broader guide to common childhood illnesses, and it is general health information rather than a substitute for care from your child’s provider.
What counts as a fever?
A fever is a temperature of 100.4°F (38°C) or higher. Anything below that is not considered a fever, even if your child feels warm. Just as important, the exact number tells you less than you might think. A child who is drinking, resting, and still has moments of play is usually doing okay, even with a fever. A child who is very hard to wake or comfort deserves attention, even if the number is not sky-high. How your child looks and acts is the better guide.
How to take your child's temperature
The most accurate way to check depends on your child’s age. Using the right method matters most for babies, where an accurate reading changes what you do next.
- Babies under 3 months. A rectal temperature with a digital thermometer is the most accurate, and it is the reading your pediatrician will want for this age.
- Toddlers and young children. An underarm (axillary) reading works well for everyday checks, with a rectal reading when you need to be sure.
- Older children. An oral thermometer is reliable once a child can hold it under the tongue with the mouth closed.
Forehead and ear thermometers are convenient, but they can be less reliable in young infants, so trust a rectal reading when it counts.
Why fevers happen, and why they are usually not the enemy
A fever is one of the body’s main tools for fighting infection. When the immune system detects a virus or bacteria, it raises the body’s temperature to help fend it off. In other words, a fever is often a sign that your child’s body is working the way it should. Fevers themselves are generally harmless, and the height of the fever does not reliably tell you how serious the illness is. This is why comfort and behavior, not the thermometer alone, guide good decisions.
When to call the doctor about a fever
Age changes the rules more than anything else. Use this as a general guide, and remember that a phone call is always a reasonable first step.
| Your child’s age | When to call your pediatrician |
|---|---|
| Under 3 months | Call right away for any fever of 100.4°F or higher, even if your baby otherwise seems fine. |
| 3 months to 3 years | Call if the fever reaches 102°F or higher, lasts more than a day or two, or your child seems unusually fussy, sleepy, or unwell. |
| Older than 3 years | The number matters less than how your child acts. Call if the fever lasts more than three days, keeps climbing, or your child seems to be getting worse. |
| Any age, seek care now | Trouble breathing, a seizure, a stiff neck, a rash that does not fade when pressed, very hard to wake, signs of dehydration, or your instinct that something is seriously wrong. |
When something feels wrong, trust that instinct and call. The team at White’s Pediatrics would rather hear from you early than have you worry alone. Call 706-876-2130 to reach us in Dalton, Chatsworth, or Calhoun.
How to help your child feel better at home
When a fever can be managed at home, the goal is comfort, not chasing the number down to normal.
- Keep fluids going. Offer small, frequent sips of water or an oral rehydration drink. Staying hydrated matters more than eating much.
- Rest and light layers. A calm day, light clothing, and a comfortable room help more than bundling up, which can trap heat.
- Fever medicine for comfort. Medicines such as acetaminophen or ibuprofen are often used to help a child feel more comfortable. Ask your pediatrician which is right for your child and how much to give, especially for babies. Never give aspirin to children or teens, and do not give ibuprofen to babies under 6 months without your doctor’s okay.
- Watch how they act. Check in on how your child looks and behaves over the day, and reach out if any of the warning signs above appear.

Frequently asked questions
How high does a fever have to be before I worry?
The number matters less than your child’s age and behavior. In a baby under 3 months, any fever of 100.4°F or higher is a reason to call right away. In older children, a child who is drinking, resting, and still has moments of play is usually okay to watch at home, even with a higher number. When in doubt, call White’s Pediatrics at 706-876-2130.
When should I take my child to the emergency room for a fever?
Seek emergency care if your child has trouble breathing, a seizure, a stiff neck with a high fever, a rash that does not fade when pressed, is very hard to wake, or if your instinct tells you something is seriously wrong. For most other fevers, a call to your pediatrician is the right first step.
Should I wake my child at night to give fever medicine?
Usually there is no need to wake a sleeping child just to treat a fever. Sleep helps the body heal. If your child wakes up uncomfortable, you can offer comfort measures then. Ask your pediatrician if you are unsure.
Can teething cause a high fever?
Teething may cause a slightly warmer temperature and fussiness, but it does not cause a true high fever. If your teething baby has a fever of 100.4°F or higher, look for another cause and call your pediatrician, especially for young infants.
What is a febrile seizure, and is it dangerous?
A febrile seizure is a convulsion that can happen when a young child’s temperature rises quickly. They are frightening to watch, but most are brief and do not cause lasting harm. Keep your child safe on their side, do not put anything in their mouth, and call your pediatrician afterward. If a seizure lasts more than a few minutes, call 911.
The fever went up after I gave medicine. Did I do something wrong?
No. Fever medicine helps with comfort, but it does not always bring the temperature all the way down, and fevers often rise and fall while the body fights an infection. Focus on how your child is acting and staying hydrated, and call if you are concerned.
Can I get my child seen the same day for a fever?
Yes. White’s Pediatrics offers same-day sick visits and welcomes walk-ins at all three locations in Dalton, Chatsworth, and Calhoun, with evening and weekend coverage at the Dalton Urgent Care. Call 706-876-2130 to be seen.
