This chart shows you the normal ranges for the different methods of taking your child’s temperature. Print this resource and post it on the fridge or keep it close to your thermometer as a handy reference for when you need it.
Method | Normal temperature range |
Rectum | 36.6°C to 38°C (97.9°F to 100.4°F) |
Mouth | 35.5°C to 37.5°C (95.9°F to 99.5°F) |
Armpit | 34.7°C to 37.3°C (94.5°F to 99.1°F) |
| Ear | 35.8°C to 38°C (96.4°F to 100.4°F) |
The degree of a fever does not tell you how serious your child’s illness is. How a child acts is usually a better sign. A child with a mild infection can have a high fever, while a child with a severe infection might have no fever at all.
