Your baby having a fever can be one of the first signs that they are feeling under the weather.
As a parent, one of the biggest challenges is when your baby is feeling unwell. When it’s warm outside, it can be hard to differentiate between your child simply feeling hot, or having a fever; the latter of which is usually a sign that your baby’s immune system is trying to fight off some form of infection.
Whilst you may be able to spot some signs of a fever in your child’s behaviour, it’s always safer and more reliable to use a baby thermometer, which can take an accurate reading of your baby’s internal body temperature.
According to the NHS, a baby’s normal body temperature averages around 36.4oC (varying slightly from one child to the next) - and a temperature of over 38 degrees is considered to be fever.
Whilst most fevers in children are a natural process that resolves itself within a few days, the NHS recommend you ring 111 and seek medical advice if your baby is less than 3 months and has a temperature of over 38, or is 3-6 months old with a temperature of over 39. You should also familiarise yourself with other signs of more serious illness here.
What should you consider when buying a baby thermometer?
Before making your choice of baby thermometer, here are some things you may want to bear in mind:
- Ease of use - With infants and babies, particularly ones that are feeling poorly, it can be challenging to get an accurate temperature reading. Whilst rectal thermometers can produce accurate results, they aren’t the preferred option for obvious reasons. Popular choices for babies that are simple and easy to use include infrared forehead thermometers (often described as ‘no contact’ thermometers), and inner-ear thermometers, many of which are used by your local GP and medical teams and for newborns. For newborns, underarm thermometers are usually the easiest and safest to administer.
- Speed of results - The easiest baby thermometers to use are those that require your baby to keep still for the shortest time possible - so you should look for thermometers that can provide an accurate reading in seconds. The good news is, the majority can these days, although some require more interpreting than others.
- Ease of reading results - Is the result displayed digitally or do you need to measure and interpret the reading yourself? Does it give a reading in both Celsius and Fahrenheit, or can you alternate between the two? If you’re worried your child is unwell, the sooner you can see the result the better.
- Does it have a backlight? - The last thing you want to do is wake your child if they’ve finally nodded off to sleep, but you may feel more comfortable checking their temperature during the night. A backlit screen can be really useful, as it allows you to quickly get peace of mind without disturbing your child.
- Trusted brands - You’ll notice that there is some consistency with the brands featured in this guide - Braun and Tommee Tippee in particular have a solid reputation for creating award-winning, accurate and high-quality baby products that are loved and trusted by many parents and have a large number of positive consumer reviews. Whilst the brand choice may be easy, there are a variety of products which you can choose from to suit your family’s needs.
Many parents use baby thermometers simply to offer peace of mind. Whether you prefer an inner-ear baby thermometer, an underarm thermometer or even bath and room thermometers to make sure your baby doesn’t overheat; here are the best baby thermometers you can buy today.

Braun Age Precision Stick Thermometer
An alternative to an inner ear thermometer comes from the leading health gadget brand. The Braun Age Precision Stick Thermometer comes with a gentle flexible tip that when placed under the arm, can take an accurate temperature measurement in eight seconds.

For best results, you should use it when your baby is calm and comfortable and their underarm is easily accessible, such as when your baby is sitting upright on your lap.
With age-adjustable measurements that allow the thermometer screen to change colour according to the level of fever, this stick thermometer will also let out ten short sharp bursts of sounds if a high fever is detected. With internal memory, it will record the last measurement too, helping you identify any spike or trends in your child’s temperature.
