A childhood fever can be alarming, particularly for parents experiencing it for the first time. While a raised temperature is usually the body’s natural response to fighting an infection rather than an illness itself, knowing how to provide appropriate first aid for childhood fever can help keep a child comfortable and identify when urgent medical care is needed. Understanding what causes fever, recognising warning signs and responding calmly are valuable skills for every parent, grandparent, educator and caregiver.
Key Takeaways
- Most childhood fevers are caused by common viral infections and improve with supportive care.
- Keeping a child comfortable and well hydrated is usually more important than simply lowering their temperature.
- Learn the warning signs that require urgent medical assessment, including breathing difficulties, severe drowsiness or a rash that does not fade.
- Febrile seizures can be frightening but are usually brief and require calm, appropriate first aid.
- Accredited HLTAID012 first aid training provides practical skills to respond confidently to childhood illnesses and emergencies.
Understanding Childhood Fever
Fever is one of the most common reasons children visit a doctor or emergency department. Despite the concern it causes, fever is not an illness in itself. Instead, it is a normal defence mechanism that helps the immune system fight infections.
A child’s normal body temperature varies slightly throughout the day but generally sits around 36.5°C to 37.5°C. A temperature of 38°C or higher is generally considered a fever.
Children often develop fevers quickly, sometimes within just a few hours. While the number on the thermometer may seem worrying, the child’s overall condition is usually more important than the exact temperature.
Many children with temperatures above 39°C remain alert and active, while another child with a lower fever may appear quite unwell. Looking at the whole child—not just the thermometer—is an important principle of good first aid.
Why Do Children Develop Fevers?
The vast majority of childhood fevers are caused by infections as the immune system responds to illness.
Recognising Fever Symptoms
A child with a fever may experience far more than simply feeling hot. Physical symptoms and changes in behaviour can both provide important clues.
How to Measure a Child's Temperature
Accurate temperature measurement helps guide decisions but should never replace careful observation of the child’s overall wellbeing.
Digital thermometers provide the most reliable readings. Depending on the child’s age, temperatures may be taken:
- Under the arm (axillary)
- In the ear (tympanic)
- Across the forehead using approved devices
- Orally in older cooperative children
Mercury thermometers should no longer be used due to safety concerns.
Touching a child’s forehead alone is not an accurate way to determine whether a fever is present.
First Aid for Childhood Fever
When a child develops a fever, the goal is not necessarily to return their temperature to normal immediately. Instead, first aid focuses on keeping them comfortable while monitoring for signs that medical assessment is required.
The first steps are usually straightforward.
- Encourage regular fluids to reduce the risk of dehydration. Small, frequent drinks are often better tolerated than large amounts at once.
- Dress the child in lightweight clothing and avoid excessive blankets. Contrary to popular belief, wrapping a child tightly to “sweat out” a fever may actually increase body temperature.
- Allow the child to rest, but there is no need to force complete bed rest if they feel like quiet play.
- The room should remain comfortably cool without making the child shiver.
Monitor the child’s behaviour regularly. A child who continues to smile, drink fluids and interact is often less concerning than one who becomes increasingly lethargic or difficult to wake.
Should You Use Fever-Reducing Medication?
Parents often feel pressure to reduce every fever immediately. Current medical advice focuses on treating discomfort rather than treating the thermometer reading itself.
Paracetamol or ibuprofen may be appropriate for children who appear uncomfortable, provided they are used exactly according to age and weight recommendations and only when suitable for that child.
- Never exceed recommended doses.
- Aspirin should never be given to children because of the risk of Reye’s syndrome.
- Medication should never replace medical assessment if concerning symptoms develop.
Keeping Children Hydrated
Children lose fluids more quickly than adults, particularly when a fever is accompanied by vomiting or diarrhoea.
When Is a Fever an Emergency?
Most childhood fevers resolve without complications. However, certain symptoms require urgent medical attention.
Febrile Seizures: A Frightening but Usually Temporary Emergency
One of the greatest fears parents have is witnessing a febrile seizure. These seizures occur in a small percentage of children, typically between six months and five years of age, during a rapid rise in body temperature.
Although frightening, most febrile seizures are brief and do not cause permanent brain damage.
During a seizure:
- Stay calm.
- Place the child on their side once safe to do so.
- Remove nearby hazards.
- Do not restrain the child.
- Do not place anything into their mouth.
- Time the seizure if possible.
- Call Triple Zero (000) if the seizure lasts longer than five minutes, breathing does not return to normal afterwards, or it is the child’s first seizure.
Following the seizure, every child should receive medical assessment.
Common Fever Myths
Many well-intentioned home remedies continue to circulate despite lacking evidence. Knowing what is fact and what is myth can help parents and carers respond more safely.
Preventing the Spread of Childhood Illness
While not every infection can be prevented, sensible hygiene measures can significantly reduce transmission at home, school and childcare.
Why First Aid Training Matters for Parents and Educators
Most childhood fevers are mild, but every parent or educator hopes they will know exactly what to do if a child suddenly becomes seriously ill.
Nationally accredited HLTAID012 Provide First Aid in an Education and Care Setting equips childcare educators, teachers, early learning professionals, parents and carers with practical skills to recognise medical emergencies, manage febrile seizures, respond to choking, asthma, anaphylaxis, burns, bleeding and CPR situations involving infants and children.
Knowing how to assess a child calmly, provide immediate first aid and recognise when emergency services are needed can make an enormous difference during stressful situations.
If you regularly care for children, consider strengthening your practical emergency skills by completing the nationally accredited HLTAID012 Provide First Aid in an Education and Care Setting course with First Aid Pro Melbourne. The hands-on training prepares you to respond confidently to childhood illnesses, injuries and medical emergencies, giving you the knowledge to help protect the children in your care.

FAQs
What temperature is considered a fever in a child?
A body temperature of 38°C or higher is generally considered a fever. However, a child’s overall behaviour and appearance are often more important indicators than the temperature alone.
Should I wake my child to give fever medicine?
Not usually. If your child is sleeping comfortably, allowing them to rest is often beneficial. Seek medical advice if you are concerned about their condition or if they are difficult to wake.
Can a high fever cause brain damage?
Typical fevers caused by infection do not usually cause brain damage. Extremely high body temperatures resulting from heatstroke are a different medical emergency and require immediate treatment.
What should I do if my child has a febrile seizure?
Stay calm, protect them from injury, place them on their side when safe, do not put anything in their mouth and call Triple Zero (000) if the seizure lasts longer than five minutes, if it is their first seizure or if you have any concerns.
When should I take my child to a doctor for a fever?
Seek prompt medical assessment if your child is under three months old with a fever, has difficulty breathing, becomes unusually drowsy, develops a non-blanching rash, experiences persistent vomiting, shows signs of dehydration or simply appears seriously unwell despite home care.
