How to measure a fever correctly, comfort your child, and recognise the signs that need a doctor tonight.
What a fever really means
A fever is a body temperature at or above 38°C (100.4°F). It is the immune system turning up the heat to slow down viruses and bacteria. The number on the thermometer matters far less than how your child looks and behaves.
How to take the temperature
- Under 3 months: a rectal reading is the most reliable
- From 3 months: forehead or ear thermometers are fine for everyday use
- Do not add or subtract degrees; simply note the value and the time
What helps at home
- Offer small drinks often; hydration matters more than food
- Dress lightly, keep the room comfortable, no cold baths
- Paracetamol at the dose written for your child's weight if they are uncomfortable
- Rest; there is no need to wake a sleeping child to give medicine
Call a doctor without waiting if
- Your baby is under 3 months old and has any fever
- The child is very hard to wake, floppy, or unusually confused
- Breathing is fast, noisy or laboured
- A rash appears that does not fade when pressed with a glass
- The fever lasts more than 3 days, or the child stops drinking
