Safe Sleep Guidelines Around the World: AAP, NHS, HAS Compared

Whether you live in the United States, the United Kingdom, Canada, Australia, or France, or you simply read several sources on baby sleep safety, official infant safe sleep guidelines look remarkably similar from one country to the next. A few details genuinely differ, though, and they are worth explaining clearly. Here is what the AAP, the NHS and Lullaby Trust, Health Canada, Red Nose Australia, and France's HAS actually say about baby's sleeping arrangement, point by point.

What every health authority agrees on

All five authorities agree on the same foundation: baby sleeps on their back, on a firm flat mattress, in a sleep space free of pillows, blankets, crib bumpers and soft toys, sharing a room with parents (without bed-sharing) for several months. This foundation rests on decades of converging epidemiological data on sudden infant death, and it aims above all to keep babies safe without overcomplicating family life.

In the United States, this guidance comes from the American Academy of Pediatrics (AAP); in the United Kingdom, from the NHS and the Lullaby Trust; in Canada, from Health Canada; in Australia, from Red Nose Australia; in France, from the Haute Autorité de Santé (HAS) jointly with the Ministry of Health. All insist on the same simple principle: sleeping on the back, in their own sleep space, remains the best-validated way to keep a baby safe during sleep, with no alternative practice shown to be equally safe.

The "Back to Sleep" campaign (United States, 1994) and its equivalents in the UK, Canada, Australia, and France each cut sudden infant death rates by more than half in the years that followed their launch. This consistent result, reached independently across several continents, is one of the strongest pieces of evidence for the safety of back sleeping.

The AAP in the United States: recommendations in detail

The American Academy of Pediatrics updated its guidance in 2022 in a policy statement that remains the most-cited international reference on the topic (AAP, 2022). It recommends back sleeping until baby's first birthday, on a firm flat surface with no inclined sleep surfaces, in a crib free of any soft object, breastfeeding, avoiding exposure to nicotine, alcohol or other substances, following the recommended vaccination schedule, and offering a pacifier at sleep times.

The AAP recommends room-sharing ideally for 6 to 12 months, a longer window than most other authorities, while insisting bed-sharing should be avoided. Notably, the AAP explicitly advises against using home cardiorespiratory monitors as a strategy to reduce SIDS risk, citing insufficient evidence of their effectiveness for that specific purpose.

The NHS and Lullaby Trust in the United Kingdom: recommendations in detail

The NHS and the Lullaby Trust charity summarize their guidance simply: always place baby on their back, in their own clear cot, Moses basket or bedside crib with a firm flat waterproof mattress, in a room kept at 16 to 20 degrees Celsius. Room-sharing, day and night, is recommended for at least the first 6 months, in a completely smoke-free home.

The Lullaby Trust explicitly recommends offering a pacifier at every sleep once breastfeeding is well established, based on data showing an associated risk reduction. This is the most explicit and systematic recommendation of the group on this specific point.

Health Canada and Red Nose Australia: recommendations in detail

Health Canada recommends room-sharing on a separate sleep surface for the first six months, back sleeping on a firm flat surface, and a completely smoke-free environment, closely mirroring the NHS and HAS timeline rather than the AAP's longer window.

Red Nose Australia takes a slightly different approach to room temperature: rather than recommending a specific number of degrees, it advises dressing baby the way you would dress yourself for the room, keeping baby's face and head uncovered during sleep, since babies regulate their temperature largely through the head and face. Red Nose's six core safe sleep recommendations otherwise align closely with the other four authorities: back sleeping, a safe cot environment, room-sharing, breastfeeding, and a smoke-free, drug-free pregnancy and environment.

France's HAS: recommendations in detail

France's Haute Autorité de Santé recommends placing baby on their back, on a firm mattress sized exactly to the crib (no gap between the mattress and the crib walls), in a baby sleeping bag rather than a blanket. The room should stay between 18 and 20 degrees Celsius and remain smoke-free.

Room-sharing without bed-sharing is recommended for the first 6 months: it makes nighttime feeds easier and reassures parents through a constant presence, while keeping baby in their own sleep space. Beyond 6 months, the HAS considers that a separate room supports independent sleep. The HAS stays more neutral than its English-speaking counterparts on pacifier use, without placing it at the same priority level as back sleeping or a bare sleep space.

Setting up a safe sleep space, wherever you live

Beyond back sleeping, the sleep environment itself follows a few simple rules that are identical across all five countries: a firm mattress covered by a simple fitted sheet, no pillow, no duvet, no crib bumper, and no soft toy in the sleep space, so baby stays free to move and the suffocation risk stays as low as possible.

For clothing, most authorities recommend a sleep sack sized to baby rather than a loose blanket, so baby cannot end up with their head covered by fabric during sleep. Room temperature, humidity, and good ventilation both limit overheating risk and reduce dust mite buildup in bedding, two factors linked to less restorative sleep.

Back sleeping can, in some babies, contribute to positional flat head syndrome (plagiocephaly): all five authorities recommend regular supervised tummy time during awake periods to reduce this risk, without ever changing baby's sleep position at night, a change that can be dangerous outside explicit medical advice. Finally, a car seat or stroller is not designed for prolonged sleep: baby should be moved to an appropriate sleep space (crib, bassinet, moses basket) as soon as possible after a car ride or walk, a principle shared by every country's guidance on transporting young children.

A dark room (close blinds or use blackout curtains) kept at a comfortable temperature helps consolidate infant sleep cycles, while staying supportive of sleep without becoming a risk factor itself. A crib or bassinet genuinely sized to baby, neither too large nor too small, prevents baby from getting stuck against the sides during sleep, and lets baby move freely, as recommended across every country's guidance.

None of the five authorities recommend swaddling your baby as a substitute for these basics: if you do swaddle, baby must still be placed on their back, the swaddle should stop above the hips once baby shows signs of rolling, and it should never be used inside a bassinet where baby could roll onto their stomach unable to self-correct. Sleep training, choosing when and how to help baby learn to fall back asleep alone, is a separate parenting decision from sleep safety, and none of the five authorities ties a specific sleep training method to their safe sleep recommendations.

Bed-sharing: the most debated question

Bed-sharing, also called cosleeping (sharing an adult bed with baby), is the point where authorities communicate most differently, even though the underlying message stays close: room-sharing is encouraged, bed-sharing is not, except in very specific, carefully managed circumstances. France's HAS and public health authorities take a pragmatic approach, detailing precautions for parents who choose occasional bed-sharing anyway (firm mattress, no duvet, no alcohol or tobacco, baby never left alone with another child or a pet, never on a sofa or armchair).

Cosleeping is accepted, and even the cultural norm, in many parts of the world: in many cultures, sleeping in the same bed as a baby is simply a traditional sleep practice passed down across generations, not a safety debate. This cultural practice is real and worth naming honestly, but the safety data behind these five countries' guidelines does not vary by culture: the same physiological risks apply everywhere, which is why every authority covered here, regardless of how common cosleeping is locally, offers a safer version of it rather than pretending the practice does not exist. Safe cosleeping, when a family chooses it, means a firm surface, no soft bedding, a sober and non-smoking adult, and baby never left alone.

The AAP more firmly recommends avoiding bed-sharing altogether, especially before 4 months, the period of highest associated risk. The Lullaby Trust takes a middle-ground position, offering detailed "safer co-sleeping" guidance for families who already bed-share, rather than an outright prohibition. Health Canada and Red Nose Australia both lean closer to the AAP's firmer stance. Across every country, the central message stays the same: putting your baby to sleep on their back, in their own sleep space, remains the best-documented way to keep a baby safe during sleep.

What's universal and what genuinely varies

Back sleeping, a firm flat mattress, no soft bedding, room-sharing without bed-sharing, and a smoke-free environment are universal: none of the five authorities departs from these principles. The real nuances involve the recommended room-sharing duration (6 months for the NHS, Health Canada, and France's HAS, up to 12 months for the AAP), how firmly pacifier use is recommended (explicit and systematic in the UK and US, more neutral in France), and room temperature guidance (a specific range in the UK and France, a "dress for the room, keep the face uncovered" approach in Australia). These differences reflect slightly different readings of largely convergent global data, not a genuine disagreement.

These recommendations apply to naps just as much as nighttime sleep: baby should sleep on their back every time, day or night, so that their sleep environment is genuinely suited to them and not only when parents happen to think of it. A crib should stay just as free of soft bedding during the day as at night, since baby's still-immature circadian rhythm does not distinguish naptime risk from nighttime risk.

No connected device, including Mothair, replaces these recommendations. Tracking baby's wellness during sleep can offer parents a reassuring reference point and support better sleep habits at home, but a sleep environment that follows your national health authority's guidance remains, in every country covered here, the real foundation of safety. Whether baby sleeps alone in their own crib or shares your room, these safe sleep practices apply the same way to every sleep, and sleeping in the same room as your baby for the recommended period, in a sleep area kept free of soft bedding, is what actually helps reduce the risk of sleep-related infant death, not any single product.

Whether it is called sudden infant death syndrome (SIDS) in the United States, Canada, and Australia, sudden unexpected death in infancy (SUDI) in some clinical contexts, cot death colloquially in the UK, or mort inattendue du nourrisson in France, prevention rests on the same basic safe infant sleep environment, and the same core sleep practices reduce the risk of sudden infant death syndrome no matter which country's terminology you grew up with. A sudden infant death remains thankfully rare when these recommendations are followed, and the risk drops markedly once they are put into practice from birth. For more on the science behind these recommendations, our guide on SIDS prevention covers the physiological mechanisms involved.

FAQ

Are safe sleep guidelines the same in every country?

On the essentials, yes: place baby on their back, on a firm flat mattress, in a sleep space free of pillows, blankets and crib bumpers, and share a room with your baby (without bed-sharing) for several months. The AAP, the NHS and Lullaby Trust, Health Canada, Red Nose Australia, and France's HAS all agree on these fundamentals, with a few secondary nuances.

Why does room-sharing guidance vary slightly by country?

The NHS, Health Canada, and France's HAS recommend room-sharing for at least 6 months, while the AAP recommends ideally keeping it up for 6 to 12 months. This difference reflects slightly different readings of the same epidemiological evidence, not a disagreement on the principle itself.

What does each country say about pacifiers and SIDS risk?

The AAP and the UK's Lullaby Trust both associate offering a pacifier at sleep times with a reduced SIDS risk once breastfeeding is well established. France's HAS stays more neutral on this specific point, without placing it at the same priority level as back sleeping or a bare sleep space.

Does a connected device like Mothair replace these recommendations?

No. No wellness tracking device, including Mothair, replaces a safe sleep environment that follows your national health authority's recommendations. These guidelines remain the essential foundation; a wellness device only adds a reassuring extra data point, never protection on its own.

Is there a safer sleep position than the back once baby gets older?

No: from birth until baby can roll over on their own in both directions, back sleeping remains the recommended position, without exception, across the AAP, NHS, Health Canada, Red Nose Australia, and HAS. Sleeping on the stomach remains associated with higher risk; only change baby's sleep position after explicit medical advice, never on your own initiative. Once baby can roll both ways on their own, they no longer need to be repositioned during the night: prevention rests on the position at sleep onset, not on continuous repositioning.

Do I need to wake my baby to check their sleep position?

No, you do not need to wake your baby to check or change their position during the night: these recommendations apply to how you place baby down to sleep, not to continuous monitoring through the night. Once a baby can roll over on their own, the position they end up in is no longer considered a risk, as long as they were placed on their back at sleep onset and their sleep space stays free of soft bedding, with a mattress sized correctly to the crib.
