Safe Infant Sleep In Winter

by Bump, Baby & You

With the colder months approaching, many of us are starting to think about the best ways to keep our babies warm enough at night!

This topics brings a whole host of factors to consider. We’ll be taking a look at the evidence based guidance from The Lullaby Trust and the NHS to help you out!

  • What is the ideal bedroom temperature?
  • How warm is too warm?
  • How can I keep my baby the ideal temperature at night during winter?
  • Should baby wear a hat to bed?

What is the ideal bedroom temperature?

The Lullaby Trust advises that the best temperature for a nursery is between 16-20 degrees Celcius; not too cold, and not too hot. It’s important that your baby doesn’t get too warm because overheating is a SIDS risk factor.

How warm is too warm?

Anything above 20 degrees Celsius is considered too warm for a safe sleep environment. To ensure your baby isn’t too warm, the Lullaby Trust advises;

  • Feel their tummy or the back of their neck – if they’re sweaty, remove a layer of clothing/bedding.
  • Don’t worry about cooler hands and feet, this is perfectly normal.

How can I keep my baby the ideal temperature at night during winter?

The NHS and Lullaby Trust both advise using lightweight fitted bedding, in layers, rather than a single very thick/warm piece of bedding – a folded blanked classes as 2 layers. A well fitting sleeping bag is a great choice too – those sold by the Gro Company are officially endorsed by the Lullaby Trust!

It’s also advised to…

  • Not put the cot by a radiator, fire, heater or window, or in direct sunlight.
  • Don’t put a hot water bottle, electric blanket etc in the cot.
  • If using a fan for any reason, don’t point it at baby.
  • Ensure baby feeds well so is well hydrated.
  • Don’t keep the heating on all night.
  • Don’t put baby to bed wearing a hat (we’ll cover this in the next section).
  • Use fewer layers than usual if your baby is unwell.
  • Keep baby in your sleep environment until at least 6 months of age.
  • Keep the cot empty – the safe sleep guidelines can be read here.

Why Shouldn’t baby wear a hat to bed?

The Lullaby Trust and the NHS both point out that a baby’s head is really important for releasing extra body heat and maintaining their overall body temperature. Layering clothing and bedding and maintaining a good temperature in the bedroom is considered sufficient for keeping baby cosy.

Hats can also come loose, posing a potential hazard as they can cover your baby’s airways in the night.

We hope that this guide has been helpful!
