Safe Sleep Guidelines for Newborns (UK)

As a new parent, one of the most important things you can do for your newborn is create a safe sleep environment. Sudden Infant Death Syndrome (SIDS) — sometimes called cot death — affects around 200 babies a year in the UK. While the cause is not fully understood, research has identified clear steps that significantly reduce the risk. Here is everything you need to know.

The Lullaby Trust: The Gold Standard for Safe Sleep in the UK

The Lullaby Trust is the UK’s leading charity on safer sleep for babies. Their evidence-based guidance is endorsed by the NHS and forms the basis of the advice given to all new parents. The core message is simple: always place your baby on their back to sleep, in a clear and flat sleep space, in a room with you for the first six months.

The Safe Sleep ABCs

The Lullaby Trust recommends the following safe sleep basics for every sleep, day and night:

• Always place your baby on their back — this is the single most important thing you can do. Babies who sleep on their back have a significantly lower risk of SIDS

• Keep the cot clear — no pillows, duvets, bumpers, soft toys, or loose bedding. A firm, flat, waterproof mattress that fits the cot snugly is all you need

• Room share for the first 6 months — keep your baby’s cot or Moses basket in your room for all sleeps, day and night, for at least the first six months

• Never sleep with your baby on a sofa or armchair — this is one of the most dangerous sleep situations for a young baby

• Keep your baby smoke-free — both during pregnancy and after birth. Exposure to smoke significantly increases the risk of SIDS

• Avoid overheating — keep the room at around 16–20°C. Dress your baby appropriately and avoid hats indoors

What About Bed Sharing?

The NHS advises that the safest place for your baby to sleep is in their own cot or Moses basket in your room. Bed sharing (also called co-sleeping) carries an increased risk of SIDS, particularly if either parent smokes, has consumed alcohol or drugs, or is extremely tired. If you do choose to co-sleep, the Lullaby Trust’s website provides a safer co-sleeping guide with detailed guidance on reducing risk.

When Can You Introduce a Pillow or Duvet?

Pillows and duvets are not recommended for babies under 12 months. From around 12 months, a small, firm toddler pillow and lightweight toddler duvet are appropriate. Adult pillows and duvets should not be used for young children as they are too large and can cause overheating or suffocation.

What About Sleeping Bags?

Baby sleeping bags (also called sleep sacks) are a great alternative to blankets. They keep your baby warm without the risk of loose bedding covering their face. Choose a sleeping bag with the correct tog rating for the room temperature and ensure it is the right size — your baby should not be able to slip down inside it.

Breastfeeding and Safe Sleep

Research shows that breastfeeding reduces the risk of SIDS by up to 50%. Even partial breastfeeding provides some protection. If you are breastfeeding, feeding your baby in bed is common — but if you think you might fall asleep, it is safer to move your baby back to their own sleep space.

Tummy Time Is Still Important

Back to sleep does not mean your baby should never be on their tummy. Supervised tummy time when your baby is awake and you are watching is essential for developing neck and upper body strength. Aim for short sessions of tummy time every day from birth, gradually increasing as your baby grows stronger.
