Safe sleeping is one of the biggest concerns for new parents, with many spending the first few nights after their baby is born constantly monitoring them.

Newborns can easily get too hot or too cold, as they can’t regulate their own temperature very well, so using the correct type and amount of bedding is a must in the early days.

Follow our simple rules to get your baby’s bedding right first time – so you can relax and (hopefully) get more sleep yourself...

Sleep safety advice you need to know

1. Put baby to sleep on their back

When experts recommended that babies be placed to sleep on their back in the early 1990s, the rate of death from SIDS dropped dramatically. Statistics are now over 50% lower.

This is because babies who sleep on their front are more likely to overheat, have pauses in breathing, and rebreathe air they have just inhaled, which is low in oxygen.

Placing your baby to sleep on their back until they are at least 12 months is sound advice for protecting your baby – and you should make sure that relatives and babysitters know the rules, too.

Once they start rolling at five or six months old, you will find them in all sorts of different positions.

There is no need to panic, as their risk of SIDS has started to drop by this age, but it is worth moving them to their back when you find them in a different position.

It's also best to place your baby in the "feet to foot" position, with their feet at the end of their cot or Moses basket, according to the NHS.

2. Choose safe bedding

There have been several studies that link a higher risk of SIDS to soft sleeping surfaces, such as beanbags, sofas, comforters, waterbeds, and quilts. The NHS advises not to use duvets, quilts, baby nests, wedges, bedding rolls or pillows when your baby sleeps.

You should use a mattress that is firm, flat, well-fitting, clean and waterproof on the outside. Cover the mattress with nothing but a single well-fitted sheet.

Avoid using blankets and instead choose a sleeping bag that will keep your baby warm without any risk of their head becoming covered.

The "feet to foot" position will also help to prevent them from wriggling under the covers and their head becoming covered.

Never place soft toys inside the cot and avoid cot bumpers, which pose a risk to your baby and prevent air circulating freely.

3. Avoid sleep positioners

You will find various sleep positioners on sale that promise to keep your baby on their back throughout the night.

The official advice is not to use them, after a spate of infant deaths through suffocation. Instead, make a habit of checking your baby regularly.

4. Let baby sleep in their own bed

According to the NHS, there is an association between co-sleeping with your baby on a bed, sofa or chair, and SIDS.

It can be tempting to cuddle little on the sofa all evening, but being a parent is tiring and you run the risk of dozing off too.

If that happens, your baby is at a much higher than average risk of SIDS, so you should always take your sleeping baby and place them in their basket, crib or cot to sleep on their own when they drop off.

It's especially important not to share a bed with your baby if you or your partner are smokers, have recently drunk alcohol or have taken medication or drugs that make you sleep more heavily.

5. Never let them sleep for too long in their car seat

Babies can get very hot sleeping in their car seats, which means they are at a much greater risk of SIDS.

Their heads are also positioned in a way that can inhibit breathing, so you should always transfer them to their cot, crib, or Moses basket as soon as you get home.

The same rule applies for prams, bouncy seats, infant carriers, slings and swings, especially if your baby is under four months old.

In the car, you should ideally have a second adult travelling in the back with your baby, or you can use a mirror to keep an eye on them. If your baby changes position or slumps forward then it's advised to take them out and sit them upright.

6. Sleep in the same room as your baby

Statistics prove that sleeping in the same room as your baby for at least the first six months reduces the risk of SIDS significantly.

However, avoid sharing a bed with your baby as it poses risks.

Instead, place their crib, cot, or Moses basket next to your bed so they are close when they wake, and place them back inside after their feed.

7. Make sure they don't overheat

It's important that your baby doesn’t overheat when they are sleeping.

Dress them in one more layer than you would wear in the same temperature – and make sure you check on your baby regularly for signs that they are hot, such as sweating or damp hair.

Invest in a thermometer for the baby’s room so you can make sure their room is close to the NHS recommended temperature of about 18C.

Never cover their head when they are sleeping with hoods or hats, as this can increase their body temperature dramatically, and may also pose a suffocation risk.

8. Stop smoking

The NHS also advises that parents can reduce the risk of SIDS by not smoking during pregnancy or after the baby is born.

Don't let anyone smoke in the house, ask visitors to smoke outside, and avoid taking your baby into smoky places.

You can find more info on SIDS by visiting the charity Lullaby Trust, which raises awareness of sudden infant death syndrome (SIDS), provides expert advice on safer sleep for babies and offers emotional support for bereaved families.


What bedding is safe for babies?

Babies under 12 months old should not have loose sheets or blankets in their cots, or use a duvet. Either a baby sleeping bag should be used or sheets and blankets that are firmly tucked in. Babies should be in the feet to foot position, so that they cannot slip down the bed under the covers. This means their feet are at the end of the crib, cot or Moses basket.

What age can a baby have a duvet?

Babies can use a duvet in their cot from around 12 months old.

Is it safe to use blankets on babies?

It's safe to use blankets in baby's beds as long as they are firmly tucked in.

Are comforters safe for babies?

A comforter can be used from seven months as a transition tool for helping your baby get to sleep and as an accompaniment for sleep in the cot from 12 months.

Experts advise that comforters are removed from a child's cot once they've fallen asleep.
