How to keep your baby sleeping safely in cold weather

6 tips to make sure your baby's sleeping safely during the cold snap


In case you hadn’t noticed, the UK is going through a bit of a chilly patch right now ❄️ ❄️ ❄️


But when it comes to bedtime with your baby, how can you make sure they’re nice and warm but not too bundled up?

As you might already know, babies can’t regulate their body temperature in the same way adults can, so it’s easy for them to overheat (a risk factor in causing sudden infant death syndrome, or SIDS).

In winter, it might be tempting to put lots of layers on your baby and crank the heating up, but you certainly don’t want them to get too hot. 

We spoke to Kate Holmes of the Lullaby Trust, who gave us some really good tips on keeping baby warm and safe through the cold nights.

1. Know what’s a safe temperature for a baby – and have a room thermometer handy

Having a room thermometer in your baby’s nursery is highly advisable – as is keeping the room temperature at 16-20°C.

Use light bedding or a lightweight, well-fitting baby sleep bag for your little one. This should be comfortable and safe for sleeping babies.

2. Use our handy guide to get the layers right

It’s understandable that as the weather gets colder, you might think about putting more layers on your little one as they sleep. In general, stick to these guidelines if you can:

* 12°C: A sheet and 4 or more blankets
* 16°C: A sheet and 3 blankets
* 18°C: A sheet and 2 blankets
* 20-22°C: A sheet and 1 blanket
* 23°C-plus: A sheet only

We also love this chart from Grobag – which shows what to dress your little one in for bedtime (long or short sleeves, all in one suit, top and bottom or just a nappy) depending on what tog Grobag you have them in and the temperature of the room they’re in.

3. Check the back of your baby’s neck if you’re worried they might be too hot

If you want to make sure you haven’t got them in too many layers, the back of the neck, or tummy, give clearer indicators of whether your little one’s overheating than their hands or feet do. 

In addition, Kate tells us: “If your baby is too hot their skin will feel slightly clammy and sweaty, and you will need to remove some layers.”

4. Don’t put a hat on your baby

Pretty much as soon as the cold weather hits, we dig out our woolly hats. But you should never put a hat on a baby indoors, even when it’s cold – because their heads are important for maintaining body temperature and releasing heat.

5. Don’t have the heating on high all night

In super cold weather it’s tempting to pop the radiators up to full heat and leave ’em that way as you sleep – but, says Kate, that’s not such a good idea as the house could get too hot (not to mention the bill you’ll get).

If you do feel you want the central heating on through the night, she advises having it no higher than 20⁰C.  

6. Even though it’s cold – never put your baby’s cot by the radiator

You might still have the pipes on in the evening when your little one’s in their cot – so never place your crib next to a radiator as this could lead to overheating or possible burns if your baby reaches out of the cot and touches their hand on the heat.

Plus, as radiators are often under windows, you might put your baby near blind cords, too, which puts them at risk of strangulation.
