Fever in Toddlers

Normal body temperature range

The normal temperature range for your toddler is between 36.5 – 38°C but this can vary depending on where and when the temperature is taken –underarm and ear are the most accurate, although forehead is the easiest. Above 38.5°C is considered a high fever but it is not necessarily a dangerous level. It is common for fevers to spike in the evening and be lower in the mornings. If your toddler is drinking and still urinating regularly, but a bit wingy and clingy, there may be no need for concern or a trip to the doctor.

Febrile convulsion with toddler fever

The rapid rise and fall of your toddler’s temperature can trigger a febrile convulsion. Witnessing a febrile convulsion is a frightening experience but doesn’t necessarily lead to any ongoing problems. Try to stay calm as much as possible and always seek medical attention just to make sure all is ok. In Australia, you can call a registered nurse via HealthDirect (1800 022 222) for advice over the phone if you are unsure of what to do next.

What to do when your toddler has a fever

• It is important to keep your toddler cool, calm and hydrated. Provide opportunities of quiet play, rest, and regular drinks of water;
• Don’t be alarmed if your toddler is off their food when they have a fever – it’s normal and they will get their appetite back soon enough;
• Avoid dressing them in too many layers, as exposed skin helps the body to cool down;
• Use tepid water (not hot or cold) when bathing as cold bath water can cause a rapid drop in body temperature – risking a febrile convulsion. Cold water may also cause the body to shiver which raises the body temperature;
• Keep windows slightly open to allow fresh air to circulate or have a fan going where your toddler plays.
   

By helping to keep your toddler’s immune system strong you can help them fight infection on their own. Contact your doctor if you have any concerns.
