Safe Sleep for Babies: A Practical Guide for Parents

Safe sleep advice can feel like a lot to remember when you are already tired and adjusting to life with a baby. The basics are simpler than the long lists of baby products might suggest.

For every sleep, day or night, current NHS guidance recommends placing your baby on their back in a clear cot or Moses basket with a firm, flat, waterproof mattress. For the first six months, the safest place for your baby to sleep is in the same room as you.

The aim of safer sleep guidance is to reduce the risk of sudden infant death syndrome, known as SIDS, and other sleep-related dangers. You do not need an elaborate nursery or lots of specialist equipment. A simple, clear sleep space is one of the most important things you can provide.

Put your baby on their back for every sleep

The recommended sleeping position for babies is on their back.

The NHS and The Lullaby Trust advise placing babies on their backs for every sleep, including daytime naps and night-time sleep. A baby should not routinely be placed to sleep on their front or side.

If your baby becomes able to roll independently, sleep can understandably become more worrying. The Lullaby Trust advises that you should still place your baby down on their back at the beginning of every sleep. Once a baby can roll from their back to their front and back again independently, you do not need to spend the night repeatedly turning them back.

If you have been given different sleeping-position advice for your baby because of a medical condition, follow the individual guidance provided by their healthcare team.

Choose a clear, separate sleep space

For the first six months, the NHS advises that the safest place for your baby to sleep is in a cot or Moses basket in the same room as you.

The sleep space should be clear. That means keeping unnecessary objects away from your baby while they sleep.

The Lullaby Trust advises against putting items such as these in a baby’s cot:

pillows
duvets
cot bumpers
soft toys and comforters
weighted or bulky bedding
sleep positioners, wedges or straps
pods or nests
rolled towels or other soft objects placed on the mattress

A clear cot can look surprisingly empty compared with styled nursery photographs. That is a good thing. Babies do not need decorative extras around them while they sleep.

Use a firm, flat mattress

Your baby’s mattress should be firm, flat and waterproof.

The NHS advises that your baby’s head should not sink deeply into the mattress. The Lullaby Trust also recommends a firm, flat mattress with a waterproof cover.

Avoid adding extra padding to make the sleep space feel softer. A baby’s sleep surface should not have cushioned sides, raised areas or soft sections around their head.

If you are using a travel cot, follow the manufacturer’s instructions and safer-sleep guidance. The Lullaby Trust advises against adding folded blankets, quilts or additional padding beneath a baby because a travel-cot mattress feels thin or firm.

Simple and firm may look less cosy to an adult, but adult ideas of a comfortable bed are not the right guide for a baby’s sleep environment.

Keep your baby in the same room for the first six months

Room sharing means your baby sleeps in the same room as you but has their own separate sleep space, such as a cot or Moses basket.

Both the NHS and The Lullaby Trust recommend room sharing for at least the first six months, for daytime and night-time sleep.

This does not mean you have to sit beside the cot for every minute of every nap. The Lullaby Trust explains that you can leave the room briefly, but your baby is safest when you are nearby for most of their sleep.

Room sharing is different from bed sharing. If you are considering bed sharing, use current NHS and Lullaby Trust guidance to understand the circumstances in which it is particularly unsafe and how risks can be reduced.

Never fall asleep with your baby on a sofa or armchair

Tired parents can fall asleep without intending to. This is worth thinking about before you are sitting with your baby at 3am and struggling to keep your eyes open.

The Lullaby Trust warns that sleeping with a baby on a sofa or armchair is dangerous.

If you think you may fall asleep while holding or feeding your baby, plan ahead rather than relying on yourself to stay awake. Keep your baby’s safe sleep space ready and close by.

If you are worried about accidental sleep or are so exhausted that staying awake while caring for your baby is becoming difficult, speak to your partner, family, health visitor or another source of support.

Avoid letting your baby get too hot

Overheating is associated with an increased risk of SIDS, so keeping your baby comfortably warm rather than very warm matters.

The Lullaby Trust recommends a room temperature of around 16°C to 20°C for babies and suggests using a room thermometer if you are unsure.

Do not judge your baby’s temperature from their hands and feet alone, as these can naturally feel cooler. The Lullaby Trust recommends checking the skin on your baby’s chest or the back of their neck. If their skin feels hot or sweaty, remove a layer.

Clothing and bedding need to be appropriate for the temperature and the specific products you use. Avoid assuming that a particular number of layers will suit every baby in every room.

Keep your baby’s head uncovered

Your baby’s head should remain uncovered while they sleep.

The Lullaby Trust advises keeping the cot free from items that could cover a baby’s face or head. This includes pillows, toys, loose bedding and cot bumpers.

If you use bedding, follow current safer-sleep advice about how it should be positioned and secured. A correctly fitted baby sleep bag is another option, provided it is suitable for your baby and used according to the manufacturer’s instructions.

Avoid adding hats for indoor sleep unless a healthcare professional has specifically advised otherwise.

What about baby nests, pods and sleep positioners?

The number of baby sleep products available can make it seem as though a newborn needs a long shopping list.

They do not.

The Lullaby Trust advises against soft-sided pods and nests, sleep positioners, pillows, cot bumpers and similar products in a baby’s sleep space.

It also warns that no product can eliminate or reduce the risk of SIDS simply because it is marketed as a sleep-safety product.

When choosing somewhere for your baby to sleep, come back to the basic principles: clear, flat, firm and separate.

If you are unsure about a particular product, check current NHS or Lullaby Trust guidance rather than relying solely on marketing claims or social media recommendations.

Can a baby sleep in a car seat, swing or bouncer?

Car seats are designed to keep babies safe while travelling, not to replace a cot for routine sleep.

The Lullaby Trust advises that if a baby falls asleep in a car seat during a journey, they should be taken out once you reach your destination and placed on a firm, flat sleep surface.

Similarly, if your baby falls asleep in a swing or bouncer, The Lullaby Trust recommends moving them to their own separate sleep space and placing them on their back.

It can be frustrating to disturb a baby who has finally fallen asleep, especially after a difficult day. Safer positioning and a suitable sleep surface still take priority over preserving the nap.

What if your baby only sleeps while being held?

Many young babies settle most easily in someone’s arms. The NHS acknowledges that, particularly during the early weeks, some babies may initially fall asleep only in a parent’s arms or while a parent stands beside their cot.

That does not mean you have done anything wrong.

The safety concern arises if the adult holding the baby falls asleep, particularly on a sofa or armchair.

If you are becoming sleepy yourself, put your baby into their safe sleep space. If nights are becoming difficult to manage because of exhaustion, ask for practical help where it is available.

Safer sleep applies to naps too

It is easy to think of safer sleep as something that mainly matters overnight, but the same principles apply to daytime naps.

Place your baby on their back in an appropriate clear, flat sleep space and follow the same guidance around mattresses, bedding and temperature.

For the first six months, NHS guidance recommends that your baby sleeps in the same room as you during naps as well as at night.

You do not need a completely different setup for daytime sleep. Consistent safety principles make things easier to remember.

Some parents plan to bed share, while others find themselves doing it unexpectedly during feeds or difficult nights.

The safest place for a baby is in their own clear, flat, separate sleep space, according to The Lullaby Trust.

If bed sharing may happen, read current NHS and Lullaby Trust guidance beforehand so you understand how to reduce risks and when bed sharing should be avoided.

The Lullaby Trust advises against bed sharing if you or anyone in the bed has recently drunk alcohol, smokes, has taken recreational drugs, or has taken medication that causes drowsiness. It also advises against bed sharing if a baby was born prematurely or had a low birth weight.

Never sleep with your baby on a sofa or armchair.

Rather than assuming you will never accidentally fall asleep, having a safer plan in advance can be particularly valuable during exhausting nights.

A simple safe sleep checklist

You do not need to memorise dozens of rules. Before putting your baby down, check the basics:

Place your baby on their back.
Use a clear cot, crib or Moses basket intended for sleep.
Use a firm, flat, waterproof mattress.
Keep pillows, duvets, cot bumpers, soft toys, nests and positioners out of the sleep space.
Avoid overheating.
Keep your baby’s head uncovered.
Keep your baby smoke-free.
For the first six months, have your baby sleep in the same room as you.
Follow the same safer-sleep principles for naps and night-time sleep.
Never sleep with your baby on a sofa or armchair.

Safe sleep does not need to look picture-perfect. In fact, a plain, uncluttered cot is exactly what recognised safer-sleep guidance recommends.

When to get professional advice

Speak to your midwife, health visitor, GP or paediatrician if you are unsure how safer-sleep guidance applies to your baby, particularly if your baby was born prematurely, has a medical condition or you have received individual medical advice about sleeping position or feeding.

Seek medical advice if you are concerned about your baby’s breathing, colour, temperature, feeding, responsiveness or general wellbeing.

If exhaustion is making it difficult for you to care for your baby safely, tell your health visitor, GP or someone you trust. You do not need to wait until you are completely overwhelmed before asking for practical support.

For up-to-date safer-sleep advice, use recognised sources such as the NHS and The Lullaby Trust rather than relying on social media posts, product claims or advice that may no longer reflect current guidance.
