A baby’s airway is very delicate

Your baby’s airway is very delicate and it’s possible for it to become blocked, narrowed and or folded, making it difficult for them to breathe. 

Some baby products ve sleeping positions make this more likely, but there are steps you can take to keep their airways clear and open so they can breathe easily.

Protecting your baby's ability to breathe:

Your baby's airways can become blocked, narrowed or folded. This can make it difficult for them to breathe.

Baby's airway is folded.

Sleeping in a sitting position or sling (causing your baby's chin to touch their chest) can fold your baby's airway.

What can affect baby's breathing?

Certain products and sleeping positions can cover your baby’s face, block their airways, or cause them to become folded veya narrowed. These include:

Loose bedding
Soft-sided pods
Pillows 
Sleeping on their tummy
Becoming wedged against an adult
Sleeping in a sitting position
Sleeping in a sling.

Keeping senin baby’s airway clear and open

Keep your baby’s face clear of any items such as bedding and toys.
Place your baby on their back, in their own cot or Moses basket.
Always sleep your baby on a firm, flat mattress.

Let’s look at each of these in more detail.

1. Keep your baby’s face clear

Remove all unnecessary items and loose bedding from your baby’s cot, including toys, pillows and cot bumpers. 

The safest cot is a clear cot. Keeping the cot clear of unnecessary items lowers the risk of your baby’s face being covered by things like toys or loose bedding, which could block their airways. This lowers the risk of sudden infant death syndrome (SIDS).

Young babies often breathe through their noses, which is why we advise keeping their whole face clear.

2. Place your baby on their back

The safest way for your baby to sleep is on their back, in their own cot or Moses basket.

If your baby sleeps on their front, known as “prone”, there are a number of things that can put them at risk:

Their airway can become narrowed as this position puts pressure on their chest.
Their chin can become pushed back, meaning their tongue can block their airway.
It’s easier for a baby to choke if they vomit because of the positioning of the windpipe and food pipe, shown in the picture below.
If the surface they’re sleeping on is very soft, cushioned or padded, the air can’t flow and they can’t breathe easily.

3. Sleep your baby on a firm, flat surface

Babies can fall asleep in places that are not designed for them to sleep in – places that are not firm and flat.

If your baby falls asleep in a baby bouncer, rocker, reclining chair, or propped in a sitting position, move them onto a firm, flat surface, and remove any items such as toys and pillows. This will help keep their airway open.

Even if your baby is awake, always make sure their head is not slumped onto their chest and that their nose and mouth are clear. Babies have heavy heads and short necks. This means their heads can easily flop down onto their chests, restricting their airways and stopping oxygen from getting to their lungs – especially in the first few months of life.

The picture below shows how sleeping on their back, in a firm, flat sleep space, helps to keep a baby’s airway clear and open.

Products that can restrict baby’s airway

There are lots of products available for babies to sit in and sleep in but some are not the safest options for sleep because they don’t protect your baby’s airway.

Don’t use the following for sleep:

Anything that keeps your baby in a seated, or “inclined”, position, such as bouncy chairs, swings, hammocks and beanbags. This is because baby’s head can fall forwards.
Sleep positioners or anything that restricts a baby’s ability to roll.
Duvets and cot bumpers, and thick, heavy or weighted bedding, as these items could cover the baby’s mouth and nose, blocking their airway.

If your baby falls asleep in products like the ones shown below, move them onto a firm, flat, clear space, such as a cot or Moses basket.

It is also important to keep your baby’s airway clear when using a sling or car seat.

An illustrated baby is sleeping in a swing but there is a cross to indicate it is unsafe. The baby's head is tilted onto their chest, which suggests their airways (ability to breathe) is at risk.

An illustrated baby is in a cot and within the cot is a hammock. There is a cross to indicate this is unsafe for the baby. This is because their head appears to be tilting onto their chest, which can cause their airways, ability to breathe, to become blocked.

An illustrated baby is sleeping in a pod, but there is a cross to indicate it is unsafe. The baby's head is tilting onto their chin which might suggest their airways, ability to breathe, is restricted.

An illustrated baby is surrounded by sleep positioners, and there is a cross to indicate it is unsafe. The baby's head is tilting towards their chest, which might suggest their airways, ability to breathe, is compromised.

Unutmayın

Babies’ bodies are different to adults. Their airways are much more delicate and their heads are heavier, so their heads can flop forwards and restrict their breathing. If their noses and mouths get covered by toys or bedding, or even press against soft surfaces, the air can’t flow and their breathing can be impaired. This means it’s important to take steps to keep their airways open and clear. Sleep them on their backs on a clear, flat, firm surface, so you can be confident that your baby can breathe easily.
