Make sure your baby doesn’t overheat – our advice

With the cold weather, some parents may be tempted to put more layers on their baby. However, it’s important to make sure your baby doesn’t overheat.

Baby sleeping in a cot

Babies who get too hot are at a higher risk of sudden infant death syndrome (SIDS).

Overheating can be caused by the room temperature being too high or if they have too much bedding or clothing on. As your baby can’t control their own temperature, it’s really important that they’re not too hot or cold. Babies do not need to wear hats indoors.

Firstly, for sleeping babies, the safest room temperature is between 16-20°C accompanied with light bedding and a light, well-fitting baby sleep bag.

We highly recommend using a room thermometer in any of the rooms your baby sleeps. This will help put your mind at ease and monitor the temperature.

Checking your baby’s temperature

Every baby is different and our advice on room temperature is a guide. Therefore, while it’s important to be informed about overheating, you should check your baby regularly to see if they are too hot.

Feel your baby’s tummy or the back of their neck. Your baby’s hands and feet will usually be cooler, which is normal. If your baby’s skin is hot or sweaty, remove one or more layers of bed clothes or bedding.
