Child Fever Assessment

Check what your child's temperature may mean by age, and when to seek medical help. For guidance only — always trust your instinct and contact a doctor when worried.

Use months so the assessment works for babies under 2.

Assessment

This tool gives general guidance only and is NOT a medical diagnosis or advice. It does not replace a doctor's assessment. If your child is very young, very unwell, drowsy, has a rash that does not fade, trouble breathing, or a seizure, get emergency help immediately.

About fever in children

Fever itself is the body's natural response to infection and is not usually dangerous. How the child looks and behaves often matters more than the exact number on the thermometer.

Young babies — especially under 3 months — with a fever of 38 °C (100.4 °F) or higher need prompt medical assessment, because signs of serious illness can be subtle at this age.

Child fever FAQ

What counts as a fever in a child?

Generally a temperature of 38 °C (100.4 °F) or higher. Always measure with a reliable thermometer; underarm and ear readings can differ slightly.

When is a fever an emergency?

Any fever of 38 °C or higher in a baby under 3 months, or a very high fever with drowsiness, a non-fading rash, difficulty breathing or a seizure, needs urgent care.

Should I give paracetamol or ibuprofen?

Medicines can ease discomfort but are not always needed. Follow age-appropriate dosing and ask a doctor or pharmacist — never give aspirin to children.
