You’ve brought your baby home, and everything is new—late-night feedings, endless diaper changes, and figuring out the best way to help them sleep soundly. But when it comes to sleep, safety is always a top priority, and you might be feeling a bit overwhelmed by the amount of advice out there on what’s truly safe for your little one.
Should they sleep on their back? Is room-sharing enough, or do you need to avoid bed-sharing altogether? What about the crib—how can you make sure it’s safe and not just comfy?
The ABCs of safe sleep are simple but crucial guidelines that will help you create the safest sleep environment for your baby. With the right practices, you’ll know exactly what to do to reduce risks like SIDS, and feel more confident that your baby is getting the safest sleep possible.
If you’ve ever felt overwhelmed by all the advice on baby sleep safety, you’re not alone. But don’t worry—we’ll break down the key guidelines so you can confidently create the safest sleep environment for your baby. In this guide, we’ll cover:
When you think about your baby sleeping, you want nothing more than for them to be safe, sound, and comfortable. But the sad reality is that each year in the United States, around 3,500 infants die due to sleep-related causes, including Sudden Infant Death Syndrome (SIDS) [1]. It’s an unsettling thought, but the good news is that many of these deaths are preventable with safe sleep practices.
Sleep-related deaths saw a big drop in the 1990s (finally, some good news!), but since 2000, the numbers have stayed frustratingly the same. Even more concerning? Some babies are at a higher risk due to a mix of factors—like underlying health issues and unsafe sleep environments that can be avoided with the right practices. The good news? Safe sleep habits can make a real difference!
The triple risk model helps explain how SIDS occurs:
The (AAP) emphasizes the importance of creating a safe sleep environment to reduce these risks and protect babies from sleep-related deaths. By following the ABCs of safe sleep (Alone, Back, Crib), you can create a safe space for your baby to sleep peacefully—and significantly lower the risk of SIDS and other sleep-related issues.
When it comes to safe sleep, space matters—for both you and your baby. While you might love the idea of keeping your little one close throughout the night, it's essential for their safety that babies sleep alone in their own designated sleep space.
The American Academy of Pediatrics (AAP) recommends room-sharing for at least the first six months—but not bed-sharing [2].
Room-sharing means your baby sleeps in their own bassinet or crib, within arm's reach of your bed. This arrangement reduces the risk of sudden and unexpected infant deaths, including SIDS. Room-sharing allows you to respond quickly to your baby's needs without the added risks of bed-sharing, where the baby might be smothered by bedding or an adult, or even roll into a dangerous position.
Your baby's sleep space must be free of soft items like pillows, blankets, toys, stuffed animals, and hats. These soft objects can pose a suffocation risk, so keeping the sleeping area clear of anything that could obstruct your baby’s breathing is essential.
If you’re using a pacifier, it’s fine to offer it to your baby in their crib, but make sure it's not attached to their clothes, the crib, or anything that could pose a strangulation hazard.
If the pacifier falls out during the night, there is no need to worry—your baby is fine without it.
By room-sharing and ensuring your baby sleeps alone, you’re reducing the risk of SIDS by up to 50%—keeping them close yet safely in their own space.
When it comes to sleep, one of the simplest and most important things you can do to keep your baby safe is to make sure they sleep on their back. You might have heard the phrase “Back is best”—and there’s a very good reason for that. This sleep position is the most effective way to reduce the risk of SIDS and other sleep-related dangers [4].
Placing your baby on their back to sleep is the single most important action you can take to keep them safe at night. Whether it’s nap time or bedtime, always lay your baby down on a firm, flat mattress in their crib, bassinet, or play yard. This creates the safest sleep environment.
Avoid placing your baby to sleep on couches, armchairs, or in seating devices like swings or car seats (unless they’re in the car). These spaces aren’t designed for safe sleep and can increase the risk of suffocation. Always choose a crib or bassinet with a firm, flat surface, and a fitted sheet.
By around three months, your baby might start showing off their new moves—rolling from back to tummy and tummy to back. When they can roll both ways on their own, it’s okay to let them sleep however they prefer. But the key is always placing them on their back first—even if they roll over at night.
If your baby can roll, it’s time to stop swaddling to allow them to move freely. Swaddling can restrict movement and pose a safety risk once they start rolling.
Safe sleep is a journey, and every baby’s sleep habits evolve over time. That’s where Happy Baby comes in!

One added benefit of back sleeping is that it can help reduce the risk of positional plagiocephaly [5] (flat head syndrome). Babies’ skulls are soft and malleable in the early months, so changing their sleep direction can reduce pressure on the same spot of their heads, helping prevent flat spots from forming.
Creating a safe sleep environment for your baby doesn’t have to be complicated—it’s about keeping things simple and secure. The crib is where your baby will spend most of its time sleeping, and making sure it meets safety standards is one of the best ways to keep your little one safe and sound.
The right crib = safer sleep! Choose a crib, bassinet, or play yard with a firm, flat mattress—skip the fluffy cushions and soft surfaces. A firm mattress not only keeps your baby properly supported but also reduces the risk of suffocation. Just add a fitted sheet, and you’re good to go—no pillows, blankets, or extras needed!
Your baby’s crib should be completely free of loose bedding, pillows, toys, and bumper pads. These items may look cute, but they pose a suffocation risk and can be dangerous if your baby rolls into them. Keep the crib simple—just the mattress, fitted sheet, and a wearable sleep sack if needed.
It’s important to avoid using sleep-positioning devices like baby nests, docks, pods, loungers, rockers, or nappers [9]. Although these products claim to help with sleep, they can increase the risk of suffocation and aren’t recommended by experts. Babies should sleep flat on their backs on a firm surface without the need for additional positioning aids.
Avoid letting your baby sleep on couches, armchairs, swings, or car seats (except when in the car). Once the car ride is over, transferring your baby to their crib for a safer sleep is essential. Car seats are designed for travel, not sleeping, so be sure your baby is placed in a crib once you're home.
Before using any crib or sleep product, it’s important to do your research [6]. Check for recalls, register the product, and read the manual to ensure the crib or play yard meets current safety standards. This extra step can provide peace of mind and ensure your baby sleeps in the safest environment possible.
When choosing a crib for your baby, make sure it meets the following safety standards:
Safe sleep isn’t just about the crib—it’s about the whole routine! Beyond picking the right crib and sleep position, there are a few simple, powerful habits that can help reduce the risk of SIDS and keep your baby safe. Here are some easy, everyday tips to create the safest sleep setting for your baby:
Breastfeeding is good for babies, great for sleep safety! Studies show that breastfeeding for at least six months can lower the risk of SIDS [7] while also giving your little one a healthy start. If it works for you, it’s not just a meal—it’s an extra layer of protection for your baby’s well-being!
Overheating is a sneaky little risk when it comes to baby sleep – and we don’t want any surprises! To keep your little one safe and cozy, opt for comfy sleepwear like a one-piece sleeper or a wearable blanket. As for the room?
Keep it cool – ideally between 68°F and 72°F (20°C and 22°C) [8]. If you're comfortable, they should be too! But here’s the key: don’t over-bundle them. Always check if they’re getting too warm and adjust as needed. We all sleep better when we’re just the right amount of cozy, right?
No ifs, ands, or butts—keep smoke away from your baby! Babies exposed to secondhand smoke have a higher risk of SIDS, and their tiny lungs are extra sensitive. The best way to protect them? Keep their sleep (and play) space completely smoke-free. It’s one of the simplest and most powerful ways to support their health and safety!
Tummy time isn’t just a cute little activity – it’s actually a superhero move for your baby’s development! By starting early, you’re helping to reduce the chances of those flat spots on their head while building up some serious neck and arm muscles.
With a newborn, you can start by laying your baby on its belly across your lap or chest for 30 seconds to 1 minute at a time [10]. Do this up to three times per day – think of it as a baby's mini workout. As your little one gets stronger (and maybe starts making some adorable faces while working on their skills), you can bump it up a bit. But always keep an eye on them – tummy time is a “supervised only” event!
Anyone who puts your baby to sleep should know and follow safe sleep practices. Share the ABCs of safe sleep (Alone, Back, Crib) with grandparents, babysitters, and daycare providers to ensure consistency and safety no matter who cares for your little one.
Avoid using sleep positioners, wedges, or non-prescription home monitors that claim to reduce SIDS. These products are not medically proven and, in some cases, can actually increase risks by interfering with a baby's natural movements.
Understanding your baby’s sleep habits can help you identify changes and establish a predictable routine. Logging wake times, naps, and night stretches make it easier to spot patterns and ensure your baby gets the rest they need in the safest way possible.
