The safest room temperature for your baby is between 16°C and 20°C.
When babies get too hot the chance of sudden infant death syndrome (SIDS) increases, which is why healthcare professionals recommend that the room where your baby sleeps should be kept at a temperature of between 16°C and 20°C.
Studies have also shown that sharing a room, but not a bed, with your baby for the first six months can reduce the risk of Sudden Infant Death Syndrome (SIDS).
What is a normal temperature for a newborn baby?
A normal temperature in babies and children is about 36.4C, but this can vary slightly.
A high temperature or fever is usually 38C or above.
How do I know if my baby is overheating?
Your baby may have a high temperature if they:
feel hotter than usual to touch on their forehead, back or stomach
feel sweaty or clammy
have flushed cheeks
If you think your baby has a high temperature, it's best to check with a thermometer. This can help you work out whether you need to get medical advice.

How to keep your baby safe and comfortable when sleeping
To help keep your baby at a safe and comfortable temperature when sleeping, you should only use bedding such as a baby sleep bag, not loose sheets and blankets in their cot.
Until they’re 12 months old, you should avoid using soft, bulky bedding such as duvets, quilts or blankets as these can cause overheating and increase the risk of SIDS.
How to check if your baby is too hot or too cold
Feel your baby’s tummy or the back of their neck. If their skin is hot or sweaty, remove one or more layers of their bedclothes. Your baby’s hands and feet will usually feel cooler. This is normal.
What if my baby is unwell?
If your baby is unwell, don’t be tempted to wrap them up more warmly. Babies who are unwell need fewer bedclothes, not more.
