It's 2am. Your child is burning up, whimpering in their cot, and you're staring at the thermometer reading 38.9°C wondering whether to rush to KKH or give paracetamol and go back to bed. As a dad and a doctor, I've been on both sides of that equation — and I want to help you make that call with confidence.
A fever is defined as a body temperature of 38°C or above (measured axillary/armpit, tympanic/ear, or rectal). It is your child's immune system doing exactly what it was designed to do — raising the body's temperature to make it a hostile environment for viruses and bacteria.
Fever is not the enemy. It is a symptom of something else — usually a viral infection — and in most cases, it is the body doing its job well. The goal of treatment is to make your child comfortable, not to chase a normal number on the thermometer.
This is completely normal. Children in childcare or preschool settings average 6–8 viral illnesses per year. Each one is the immune system building its library of antibodies — essentially, it is being trained on the job. By age 5–6, most children are significantly more robust. The frequent fevers of toddlerhood are the price of admission for a well-educated immune system.
Here's something that surprises many parents: the height of the fever is less clinically important than how your child looks and behaves.
A child with a temperature of 39.5°C who is alert, smiling, drinking fluids, and reaching for their favourite toy is far less concerning than a child with 38.2°C who is glassy-eyed, not responding normally, and refusing all fluids. Behaviour is the signal. Temperature is just a number.
Most fevers in children over 3 months can be safely managed at home if your child:
Paracetamol (acetaminophen) is the first-line fever and pain reliever for children. The correct dose is 15 mg/kg per dose, which you can cross-check against the age guide below. Always use the weight-based dose when possible — children of the same age can have very different weights.
| Age | Approximate Dose | Frequency |
|---|---|---|
| Under 3 months | ⛔ Do NOT give without medical advice | — |
| 3–5 months | 60 mg per dose | Every 4–6 hours, max 4 doses/day |
| 6–23 months | 120 mg per dose | Every 4–6 hours, max 4 doses/day |
| 2–3 years | 180 mg per dose | Every 4–6 hours, max 4 doses/day |
| 4–5 years | 240 mg per dose | Every 4–6 hours, max 4 doses/day |
Weight-based rule: 15 mg/kg per dose. Maximum 4 doses in 24 hours. Do not give closer than every 4 hours.
Ibuprofen (e.g., Nurofen for Children) is safe from 6 months of age and can be alternated with paracetamol for better temperature control — giving one, then 3 hours later the other, cycling through. Do not give ibuprofen on an empty stomach. Do not use in children under 6 months or in children who are dehydrated or vomiting repeatedly.
Lukewarm (not cold, not ice) water sponged over the body can help your child feel more comfortable. It does not treat the underlying illness, and cold or icy water can cause shivering which paradoxically raises core temperature. Use it as a comfort measure alongside medication, not instead of it.
If your feverish child develops a rash, press a clear drinking glass firmly against the skin over the rash. If the spots fade and disappear under pressure — they are blanching, and likely a viral rash (common, usually benign). If the spots do NOT fade and remain visible through the glass — this is a non-blanching rash and may indicate meningococcal disease or another serious condition. Do not wait. Go to the Children's Emergency immediately.
Your child is ready to return to school or childcare when they have been fever-free without any paracetamol or ibuprofen for at least 24 hours. Not "the fever went down after Panadol" — actually fever-free without medication. This protects your child (whose immune system is still recovering) and their classmates. Most childcare centres in Singapore require this as policy.
Many parents unknowingly give their child two doses of paracetamol at once. How? By giving paracetamol syrup (e.g., Children's Panadol) and a combination cold or flu syrup (e.g., many brands of children's cough-and-cold medicine) — not realising the combination product also contains paracetamol. Always read the active ingredients label. If your child is already on paracetamol syrup, they should not also receive any other product containing paracetamol. When in doubt, ask your pharmacist to check for you.
