Safe Sleep for Babies: What European Guidelines Say About Where and How Your Baby Should Sleep
Bringing your baby home for the first time is one of life's most joyful moments, and it is also one of the most anxiety-inducing. Among the many decisions new parents face, where and how their baby sleeps ranks among the most important. Sudden Infant Death Syndrome, known as SIDS, can feel like an overwhelming worry, but the reassuring truth is that following well established safe sleep guidelines can significantly reduce the risk. Across Northern Europe, including the Netherlands, Germany, Belgium, Denmark, Norway, and Sweden, pediatric health organisations share a clear and consistent set of recommendations. In this guide, we walk you through everything you need to know: the safest sleep position, how to set up a secure sleep environment, how to manage room temperature, and why room sharing in the early months makes a meaningful difference.
Always Place Your Baby on Their Back
The single most important thing you can do for your baby's safety while they sleep is to place them on their back, every single time. This applies to all sleeps: night sleep, daytime naps, and any other rest period. Research carried out over several decades has shown that placing babies on their back to sleep dramatically reduces the risk of SIDS. The back to sleep campaign, launched across Europe and North America in the 1990s, contributed to a reduction in SIDS rates of more than 50% in many countries.
Some parents worry that their baby might roll onto their side or front during the night. If your baby can only roll one way, always return them to their back. Once your baby is able to roll independently from back to front and back again, they have the developmental ability to adjust their own position, and you do not need to keep repositioning them. Until that point, always start every sleep with your baby on their back.
Avoid using positioning devices such as wedges, rolled blankets, or similar products to keep your baby in a fixed sleeping position. These are not endorsed by European pediatric safety organisations and can create additional hazards in the sleep environment.
Setting Up a Safe Sleep Space
Your baby's sleep space should be as simple and clear as possible. Pediatric organisations across Europe recommend the following for the safest cot, bassinet, or Moses basket environment.
Use a firm, flat, waterproof mattress that fits snugly within the cot or Moses basket, with no gaps where your baby's limbs or head could become wedged. Keep the sleep space completely clear. This means removing pillows, duvets, cot bumpers, soft toys, pods or nests of any kind, and any loose blankets or sheets that are not firmly tucked in. All of these items can shift during sleep and cover your baby's face, which poses a serious suffocation risk. The guidance from the UK's Lullaby Trust and equivalent Dutch and German child health authorities is consistent: the safest cot is a clear cot.
Place your baby at the foot of the cot so their feet touch the bottom end. This feet to foot position prevents your baby from wriggling down under any tucked blanket during the night.
Room Temperature and Avoiding Overheating
Overheating has been identified as a risk factor for SIDS, making room temperature one of the more underestimated aspects of safe sleep. The ideal bedroom temperature for a sleeping baby is between 16 and 20 degrees Celsius. A room thermometer placed in the nursery or in your own bedroom will help you monitor this consistently.
Check your baby's temperature by placing your hand on their chest or the back of their neck. If they feel hot or sweaty, remove a layer of clothing or bedding. Do not be alarmed if your baby's hands and feet feel cool: this is normal for young infants and is not a reliable indicator of their core body temperature.
Never place a hot water bottle or electric blanket in the cot with your baby, and avoid positioning the cot near a radiator, heater, or in direct sunlight, all of which can cause the ambient temperature to rise unexpectedly.
Room Sharing for the First Six Months
The evidence supporting room sharing during the first six months of life is strong and consistent across European health guidelines. Keeping your baby in the same room as you for all sleeps, whether at night or during the day, has been shown to reduce the risk of SIDS. Importantly, room sharing does not mean bed sharing: your baby sleeps in their own separate sleep space, such as a cot or Moses basket positioned next to your bed.
Room sharing allows you to respond quickly if your baby needs attention, and some research suggests that proximity to a sleeping adult can help regulate a newborn's breathing and arousal patterns. After the first six months, moving your baby to their own room is a personal decision that many families make confidently. However, the first six months represent the highest risk period for SIDS, so keeping your baby close during this window is strongly recommended by pediatric authorities across Europe.
Swaddling Safely in the Newborn Stage
For newborns in their first weeks of life, swaddling with a lightweight, breathable fabric can offer a wonderful sense of security, mimicking the snug warmth of the womb. When done correctly, swaddling can help a newborn feel calm and settle more easily for sleep. The key principles are straightforward: use a thin, breathable fabric so your baby does not overheat; make sure the swaddle is snug around the arms but allows the hips and legs to move freely, as tight wrapping of the legs can affect healthy hip development; and always place a swaddled baby on their back. Stop swaddling as soon as your baby shows any signs of rolling, which typically begins between two and four months of age.
The HelloLoomi Baby Swaddle Wrap for Sleeping and Cuddling is made from soft Oeko Tex Standard 100 certified cotton that keeps your newborn cozy without the risk of overheating. Its adjustable tie closure creates a secure but gentle fit, and it is machine washable for easy everyday care.
Choosing Safe Bedding for Your Baby
When it comes to bedding, less is almost always more in a baby's sleep space. Duvets, quilts, pillows, and thick blankets are not appropriate for babies under twelve months. They can shift and bunch up against your baby's face during sleep, creating a suffocation hazard.
Baby sleeping bags, sometimes called sleep sacks, are widely recommended across Europe as a safe alternative to loose blankets. They keep your baby warm without the risk of covers riding up during the night. If you prefer to use a blanket, choose something lightweight and breathable. Tuck it firmly under the mattress on both sides and at the foot of the cot, so it reaches no higher than your baby's shoulders and cannot work loose during sleep.
The HelloLoomi Soft Muslin Cotton Blanket is woven from four layers of Oeko Tex certified 100% cotton muslin, offering warmth and breathability in equal measure. Its lightweight construction makes it a good choice for pram use and as a tucked blanket for older babies, and it is gentle enough for the most sensitive newborn skin.
Bed Sharing: Understanding the Risks
Sharing a sleep surface with your baby is a deeply personal choice and one that many families across Northern Europe make. Understanding where the risks are highest will help you make an informed decision. Bed sharing is considered significantly more dangerous in certain situations: if you or your partner smoke regardless of when or where; if either of you has recently consumed alcohol; if either of you has taken medication or recreational drugs that cause drowsiness; or if your baby was born prematurely or with a low birthweight.
Sharing a sleep surface on a sofa or armchair is particularly dangerous and is strongly discouraged by all European pediatric safety organisations. If there is any chance you might fall asleep while feeding or holding your baby, move them to their own flat, firm sleep surface first. For families who choose to share a bed, the Lullaby Trust recommends placing the baby on a firm mattress on their back, keeping adult pillows and duvets away from the baby at all times, and ensuring the baby cannot roll off the edge or become trapped between the mattress and a wall.
Addressing Common Safe Sleep Myths
Safe sleep guidance sometimes runs up against longstanding beliefs or well-intentioned advice passed down through generations. A few of the most common misconceptions are worth addressing directly.
Some parents find that their baby seems to sleep more deeply on their front. While this may be true, stomach sleeping significantly increases the risk of SIDS for babies who cannot yet reliably lift and turn their own heads. Back sleeping is the non-optional recommendation of every major European pediatric authority for this age group.
Another common belief is that a small pillow in the cot will prevent or correct positional flat head, known as plagiocephaly. Positional flat head is best addressed through supervised tummy time during waking hours and varied head positions while awake, not through the use of pillows during sleep. Pillows remain unsafe in the sleep environment for babies under twelve months.
Finally, it is worth noting that baby monitors, including those that track breathing or movement, do not eliminate SIDS risk. They can offer reassurance, but they are not a substitute for the environmental safe sleep measures described throughout this guide.
A Simple Checklist for a Safe Sleep Environment
Before every sleep, it helps to run through a quick mental checklist. Your baby should be on their back, on a firm and flat clear surface, with no soft items in the sleep space. The room should be between 16 and 20 degrees Celsius, and your baby should be dressed in appropriate layers for the temperature. In the first six months, your baby should be in the same room as you. That is all you need. Safe sleep is not complicated or expensive. It is consistent, simple, and protective.
Conclusion

Frequently Asked Questions
What is the safest sleeping position for a baby?
The safest sleeping position for a baby is always on their back, for every sleep including naps. This recommendation from pediatric organisations across Europe has been associated with a reduction in SIDS rates of more than 50% since it was introduced. Once a baby can roll from back to front and back again independently, they may be left in the position they naturally move into during sleep.
How long should my baby sleep in the same room as me?
European and UK pediatric guidelines recommend keeping your baby in the same room as you for at least the first six months of life, for all sleeps including daytime naps. Your baby should sleep in their own separate sleep space such as a cot or Moses basket, not in your bed. After six months, moving to a separate room is a personal decision that families can make with confidence.
Is it safe to swaddle a baby for sleep?
Swaddling is considered safe for newborns when done correctly, using a lightweight breathable fabric that allows the hips and legs to move freely. Always place a swaddled baby on their back to sleep, and stop swaddling as soon as your baby shows any signs of rolling, typically around two to four months of age. A well-fitted swaddle wrap like the HelloLoomi Baby Swaddle Wrap for Sleeping and Cuddling is designed to provide a snug but safe fit for newborns.
Can I use a loose blanket in my baby's cot?
Loose blankets are not recommended for babies under twelve months as they can shift during sleep and cover the baby's face. If you do use a blanket, choose a lightweight breathable option such as a muslin cotton blanket, tuck it firmly under the mattress so it reaches no higher than your baby's shoulders, and use the feet to foot position. Baby sleeping bags are widely recommended as a safer alternative.
What room temperature is safest for a sleeping baby?
The ideal room temperature for a sleeping baby is between 16 and 20 degrees Celsius, according to pediatric guidance followed across the UK, Netherlands, Germany, Belgium, and Scandinavia. A room thermometer in the nursery helps you monitor this consistently. Check your baby's temperature by feeling the skin on their chest or the back of their neck rather than their hands or feet, which naturally feel cooler.
What items should I never put in my baby's cot?
Pediatric organisations across Europe advise keeping the cot completely clear of pillows, duvets, cot bumpers, soft toys, loose blankets, nests, pods, wedges, and any items intended to prop or position your baby. All of these items can move during sleep and obstruct your baby's airway. The safest cot contains only your baby, dressed appropriately for the room temperature, lying on a firm flat mattress on their back.
Is bed sharing with my baby ever safe?
Bed sharing carries a higher risk than having your baby sleep in their own separate space, and it is strongly discouraged if you or your partner smoke, have consumed alcohol, are taking sedating medication, or if your baby was born prematurely or with a low birthweight. Sharing a sleep surface on a sofa or armchair is always dangerous. For families who choose to share a bed, the Lullaby Trust provides detailed guidance on minimising risks, including using a firm mattress and keeping adult bedding away from the baby at all times.
