Understanding and managing fever in children with confidence

Fever in children is one of the most common reasons for pediatric consultations. While the sight of a flushed face and high temperature can alarm any parent, it’s important to know that in many cases, fever is not dangerous. It’s actually the body’s way of responding to infections and triggering the immune system.

Understanding when to act, how to comfort your child, and when to seek medical help is essential for every caregiver.

What Is Considered a Fever in Children?

A fever is usually defined as a body temperature above 38°C (100.4°F). In children, mild fevers are common and typically resolve on their own. However, if the fever is persistent or accompanied by other symptoms, it may need medical attention.

Fever in children is often caused by viral infections, including colds and flu, but can also be due to bacterial illnesses or post-vaccine reactions.

When to Worry About ?

You should consider calling a healthcare provider if:

• Your baby is younger than 3 months and has any fever
• The fever persists beyond 3 days
• Your child is excessively sleepy, irritable, or unresponsive
• There are signs like rash, difficulty breathing, or vomiting
• The fever exceeds 40°C (104°F)

Fever in children can sometimes indicate a more serious issue, so trusting your instincts and observing your child’s behaviour is crucial.

Managing Fever in Children at Home

For most cases, fever in children can be managed safely at home with some basic care and attention.

1. Keep them hydrated

Dehydration is a common risk when dealing with fever. Encourage frequent sips of water or oral rehydration fluids. For infants, increase breastfeeding or formula feeds.

2. Dress appropriately

Overdressing can trap heat. Use lightweight clothing and a light blanket if needed. Keep the room at a comfortable temperature.

3. Use fever-reducing medicine

Acetaminophen or ibuprofen are effective options. Always dose according to the child’s weight and age. Avoid aspirin, which is unsafe for children.

4. Monitor temperature

Check their temperature every few hours and look for changes in mood, appetite, and responsiveness.

Myths About Fever in Children

There are several misconceptions about fever in children:

• High fever does not always mean a serious infection
• Fever doesn’t automatically require medication if the child feels okay
• Teething does not cause high fevers, though it may cause a slight temperature increase

Fever in children is often a sign that their immune system is functioning properly.

Supporting Recovery During Fever

Give your child quiet time and allow for naps. Keep them engaged with calming activities and offer light, nutritious foods. Monitor their mood and ensure they’re comfortable.

Adding a lukewarm sponge bath can help lower body temperature gently — but never use cold water or alcohol rubs.
