As a parent, seeing your child's temperature rise can be one of the most worrying moments. However, it's helpful to remember that fever is not an illness in itself. It is a sign that your child's body is actively fighting off an infection, usually a viral or bacterial one. Understanding what a fever means and how to manage it can help you care for your child with confidence.
A fever is generally defined as a body temperature of 100.4°F (38 °C) or higher. The most accurate readings are often taken rectally (for infants) or orally/aurally (ear) for older children, though a temporal (forehead) or axillary (armpit) reading can give a useful quick check.
It's important to focus on how your child looks and acts, rather than just the number on the thermometer. A child with a slightly elevated temperature who is alert and playing may need less intervention than a child with a lower fever who is lethargic or irritable.
Besides the high temperature, common symptoms that accompany a fever can include:
The goal of home care is to keep your child comfortable and prevent dehydration, rather than forcing the temperature down to a specific number.
Fever can lead to fluid loss, so offering plenty of fluids is essential.
While most fevers are harmless and resolve on their own, certain signs indicate the need for immediate medical attention.
| Age of Child | Warning Sign |
| Newborns (Under 3 Months) | Any temperature of 100.4°F (38 °C) or higher (Rectal). Call the doctor immediately. |
| Any Age | Fever that persists for more than 48 hours (2 days). |
| Any Age | Non-blanching rash (a rash that does not fade when you press a glass against it). |
| Any Age | Severe symptoms like difficulty breathing, stiff neck, persistent vomiting or diarrhea, severe headache, inconsolable crying, or extreme lethargy/drowsiness. |
| Any Age | Signs of dehydration (dry mouth, sunken eyes, significantly fewer wet diapers/urine). |
It is always appropriate to call your doctor if you are simply worried or unsure about your child's condition.
