Your little one hasn’t been very well as of late. They’ve been sneezing, coughing, their appetite has disappeared and they’ve been extremely tired and tearful, too. You know that babies tend to get a lot of colds during this time in their life but you can’t help but wonder whether you should call the doctor. As this is your first child, you’re not quite sure of the best steps to take. However, one of the main measures that your mother used to resort to in your infancy was taking your temperature.

But the only issue is that you don’t quite know how to take their temperature or whether you even have the right thermometer to do so.

Taking your baby’s temperature is one of the quickest and easiest ways to give you an idea of whether you need to call the doctor for help or not. But many parents struggle to know how to properly and accurately take their babies' temperature. If you can relate to this, then rest assured you are one of many!

So, here’s a guide as to what type of thermometer you should use and how to take their temperature, so you’ll know exactly what to do the next time your baby is ill.

First up, let’s outline what type of thermometer you should be using to take their temperature.

What type of thermometer should I be using to take my baby’s temperature?

When taking your baby’s temperature, you want to get as accurate a reading as possible. Therefore, it’s always best to use a digital thermometer, as this gives a quick and accurate reading. Try to avoid other types of thermometer (like old-fashioned mercury in glass or strip-type ones) as these are often a lot less accurate and can also be hard to use if your baby is wriggly or unsettled.

How do I take my baby’s temperature?

Turn on the thermometer. Also, make sure that the screen is clear from old readings you may have done before.

Next, put a fresh disposable plastic sleeve or cover on the thermometer if you are using the type of thermometer that has them.

Sit your baby on your lap or lie them down. Simply find a position that is comfortable for you both.

Put the tip of the thermometer into the middle of their armpit.

Hold the thermometer in place. While doing this, keep your baby’s arm pressed against their body. Do this for 15 seconds.

Throw away the disposable plastic sleeve after you have finished the reading.

Are there any times I shouldn’t take my baby’s temperature?

Just after your baby has had a bath.
If your baby has been wrapped in layers for a long time.

In these two scenarios, it can be difficult to get an accurate reading as your baby will already be rather warm. Wait a few minutes for them to cool down before taking their temperature.

What should I do if my baby has a high temperature?

If your baby has a high temperature, it’s always best to call the doctor, especially if they are between 3 and 6 months and have a temperature of 39 degrees C or more, if they are under 3 months and have a temperature of 38 degrees C or more, or if your baby is irritable, floppy or lethargic.

It’s best to contact the doctor as soon as you can because although temperatures aren’t always serious, they can sometimes signify that your baby is fighting something that needs medical intervention.
