What temperature should my baby’s room be?

A safe sleeping temperature for your baby’s room is between 16 and 20 degrees. According to The Lullaby Trust, the chance of SIDS is higher in babies who get too hot, so keeping your baby’s room a comfortable temperature is important.

How can you check if your baby is too hot?

Obviously, every baby is different, and even if you’ve used a room thermometer, it’s important to check your baby regularly to ensure they are not too hot. This can be done by simply feeling your baby’s tummy, or the back of their neck, as their hands and feet will often be colder than the rest of their body. If your baby feels hot or sweaty, remove layers.

If you’re worried the temperature in the room is too hot, open a window before putting your baby down to sleep. If you’re using a fan to cool the room, ensure it is not aimed directly on your baby.

As time goes on you'll learn your baby well, so it will become easier to check their temperature and know what's normal. 

How can I ensure my baby’s room is warm enough?

Despite feeling cold in the winter, it is rare that you will need to keep your heating on all night, but if you do, ensure it is set to a low temperature no higher than 20°C. It’s often a better idea to add another layer to your baby. Remember, it’s important not to put a hat on your baby indoors as they maintain body temperature by releasing heat.

Another good way to keep an eye on room temperature is to have a baby monitor with a screen - this can also alert you of the room's temperature and for example, in the winter if you've got the heating cranked up too high, you know sooner rather than later when to turn it down.
