Get answers to commonly asked questions on baby fever, and learn how to take a baby's temperature and manage your infant's condition.
What is the temperature range for a baby fever?
Typically, your baby's normal body temperature should stay between 36.5°C and 37.5°C. Any reading above 38°C is considered a fever.
When it comes to a baby fever, the best thing you can do is be prepared. When your baby is unwell, a fever is often the first sign of trouble. Fever is usually a sign that the immune system is fighting an illness or infection.
A few things to note about fever in babies:
Over-wrapping or a warm environment can cause the baby's body temperature to be higher
How high a fever is does not indicate the severity of the illness that is causing the fever
Most childhood fevers are due to viral infection which can last from 5 – 7 days
How to take a baby's temperature?
There are several different methods of taking a baby's temperature. The best way to get an accurate temperature reading for a child younger than 3 years is by using a digital rectal thermometer. Ear thermometer, forehead thermometer and underarm readings are handy but aren't nearly as accurate.
When to call your paediatrician for fever in babies younger than 3 months old?
Call your paediatrician if your baby is below 3 months old and running a fever above 38°C. A persistent fever that lasts for more than 5 days is a cause for concern.
When to call your paediatrician for fever in babies above 3 months old?
Pay attention to your baby's symptoms and behaviour to determine how sick they are, and ask the doctor for treatment advice based on those signs. A fever usually goes away within 3 – 5 days but regardless of your child’s age, a persistent fever is a cause for concern.
If you are really worried, and if your baby's fever is coupled with the following symptoms, head to the A&E department right away or call for an ambulance.
Appears ill, drowsy or unresponsive
Has a rash that doesn't fade easily
Has a stiff neck, severe headache or seizure
