Normal body temperature is between 97 to 100 degrees Fahrenheit. It’s important to remember that body temperature changes throughout the day. It’s usually lower in the morning and higher in the late afternoon or evening. Understanding these natural changes helps parents recognize when Fever in Children may be present.

Fever in children can be caused by many things, such as viral and bacterial infections. Some common causes include:
Fever in children worries parents a lot. It means different things at different ages. As kids get older, their immune systems get stronger. But some ages are more at risk for serious infections.
Infants under 3 months are at high risk for fever. Even a small fever can mean a serious infection. The American Academy of Pediatrics says these babies need to see a doctor right away if they have a fever over 100.4 °F (38 °C).
They need quick medical help because their immune systems are not fully grown yet.
“The younger the infant, the more cautious parents should be with fever,” says a pediatrician. “It’s always better to err on the side of caution and consult with a healthcare professional.”
Toddlers and older kids have different concerns with fever. It depends on how they feel, if they have other symptoms, and how high the fever is. Fever usually means the body is fighting an infection.

Keeping your child comfortable and hydrated is key. Dress them in light clothes and make sure they rest. Offer plenty of fluids like breast milk, formula, water, or electrolyte drinks. Watch for signs of dehydration, like fewer wet diapers or dry mouth.
“Drinking enough water is important for your child’s recovery,” says an Expert pediatrician. “Encourage them to drink small amounts often to avoid dehydration.”
Medicines like acetaminophen or ibuprofen can help lower a fever. But it’s important to use them safely. Always follow the dosage on the label and talk to your pediatrician if you’re unsure. Never give aspirin to children because of the risk of Reye’s syndrome.
