Understanding Your Child’s Temperature (and When To See a Doctor)

Being a parent can be tough, especially when your child is sick.

One of the biggest confusions for parents is understanding their child's temperature - for example, what is considered a fever, when to be concerned and what to do about it?

While seeing your child's temperature rise dramatically can be quite alarming, here’s the facts to ensure you feel more confident in how to manage the fever appropriately.

First things first, a high temperature (fever) in children is considered:

  • over 38 degrees Celsius for babies under three months

  • over 38.5 degrees Celsius for older babies, toddlers and children.

Many things can cause a high temperature such as regular coughs and colds, and common childhood illness like chickenpox and tonsillitis.

Even, vaccinations can cause a fever.

This is because a high temperature is part of your body's natural response to fighting infection

- and it’s not unusual for children to have up to 12 infections with a fever per year! 

The fever, however, is just a symptom and not a disease. So, parents need to consider the child's behaviour and not just their temperature when choosing an appropriate treatment.

Checking their temperature

We recommend using a digital thermometer for a more accurate reading. Measure it 2-3 times to get an accurate estimate, with results being within 0.2-0.3 to gauge the average. 

If you don't have a thermometer, your best test is to place your hand on your child's forehead. If they have a fever they will feel like they are 'burning up'. 

Your parental instincts are also a good indicator - we know when something is not quite right with our children.

Other signs to look for before deciding on treatment

Rising temperatures don’t always correspond to illness. Children can be sick with normal or low temperatures. So, it's important to also consider these things:

·      are they in pain?

·      how is their mood?

·      are they eating?

Treatment options

Unless the temperature is prolonged, unmanageable or accompanied by other symptoms, it may not need immediate treatment by medication.

So firstly, keep your child hydrated and in light clothing, and give them lots of hugs and cuddles.

It's best to keep your child at home from day-care or school and reduce high-energy, active play while you wait for the temperature to settle.

If your child appears to be in pain and/or miserable, paracetamol can provide relief. Please ensure the correct dose on the bottle is administered according to your child’s weight rather than age.

What NOT to do when your child has a high temperature

Avoid trying to cool them down with limited clothing, cold baths and sponge-downs.
