Step-by-Step Guide

How to use this tool

This tool uses temperature thresholds based on NHMRC and WHO guidelines. It takes the measurement method into account and adjusts to a rectal equivalent for accurate interpretation.

  1. 1
    Measure your baby's temperature

    The most accurate method for infants is rectal (in the bottom). Underarm is most common in Australia. Add 0.5°C to get the equivalent rectal temperature. Forehead thermometers are convenient but less accurate. Digital ear thermometers are accurate if used correctly.

  2. 2
    Select the measurement method

    Tell the tool how you measured the temperature. It automatically adjusts to the rectal equivalent (the medical standard ). For an accurate assessment. This is very important because an underarm reading of 38°C is actually equivalent to a rectal reading of 38.5°C.

  3. 3
    Select your baby's age

    Age is critical for fever management. A fever in a newborn under 3 months is always an emergency. The same fever in a 2-year-old may just need paracetamol. The tool gives completely different guidance based on age.

  4. 4
    Select any other symptoms

    Check if your baby has a rash, difficulty breathing, seizure, or stiff neck. These symptoms change the urgency level significantly. A fever with a rash or a seizure is always urgent regardless of temperature level.

💡 How to measure temperature accurately at home

Best method: Digital rectal thermometer (for babies under 3 months). Easiest method: Infrared forehead or ear thermometer. Most common in Australia: Digital axillary (underarm). Always use the same method each time and add 0.5°C if using underarm. Keep the thermometer under the arm for a full 2 minutes with the arm pressed firmly against the body.

⚠️ Always trust your parental instinct

If your baby seems unusually limp, unresponsive, is making a high-pitched cry, has blue lips, or you feel something is seriously wrong. Go to hospital immediately even if the temperature is normal. Serious infections can sometimes cause subnormal temperature (below 36°C) in very young babies.

Frequently Asked Questions

NHMRC no longer recommends cold water sponging. It can cause discomfort. Plus shivering and actually raise core temperature. Lukewarm water sponging (water at body temperature) is acceptable to help a child who seems very uncomfortable. Never use alcohol or ice-cold water on a feverish child.
Post-vaccination fever is very common. It is a sign the immune system is responding. It typically starts 6-12 hours after the vaccine, peaks around 24 hours, and resolves within 48-72 hours.

Context for Australian families

What Australian mums actually deal with

Aussie mums tend to be pragmatic about baby illness. Cultural default leans toward "she will be right." Combined with reasonable access to nurses and GPs, this generally works. The Maternal and Child Health Nurse system is a treasure of the Australian health system. Use it without hesitation. Telehealth normalised during COVID and stayed normalised, which is genuinely useful. The unique Aussie concerns are bushfire smoke season and extreme summer heat.
