Wondering about the best way to lay a newborn to sleep? You're not alone. You might feel overwhelmed with advice from family, friends, and the internet about the "right way" to put your newborn down. Sleep safety isn't just about comfort—it's about protecting your baby from risks like SIDS. This article covers everything you need to know about safe sleep positions (especially why back sleeping matters), creating a proper sleep environment, and what to do when your little one just won't settle down.
Why Should Newborns Always Sleep on Their Back?
When you put your newborn down to sleep, positioning them on their back is the single most important step you can take to keep them safe. This isn't just a suggestion—it's the official recommendation from the American Academy of Pediatrics and has been since 1994 when the "Back to Sleep" campaign (now called "Safe to Sleep") began. Since pediatricians started recommending back sleeping, SIDS rates have decreased by more than 50%, saving thousands of babies' lives. While other sleep practices matter too, back sleeping remains the foundation of safe infant sleep.
How Back Sleeping Protects Your Baby
Back sleeping reduces your baby's risk of SIDS (Sudden Infant Death Syndrome) in several important ways. When babies sleep on their backs, they're less likely to overheat, which is a known risk factor for SIDS. The back position also keeps your baby's airway more open and unobstructed. Babies placed on their stomachs may rebreathe exhaled carbon dioxide if they can't move their heads effectively, or they might press their face against soft bedding, both potentially dangerous situations. Additionally, back sleeping helps protect against accidental suffocation that can happen when babies are placed on their sides and accidentally roll onto their stomachs.
What About Choking Concerns?
Many parents are afraid their baby will choke if placed on his or her back, especially after feeding. Research shows this is not true. Healthy babies will naturally protect their breathing passages with their gag reflex and by rolling their heads when they spit up. In addition, back-sleeping babies are less likely to choke than stomach-sleeping babies. This is due to the fact that when they are lying on their backs, the windpipe (trachea) is above the food pipe (esophagus), so spit up will simply run back down the esophagus rather than into the lungs.
When To Start And Stop Back Sleeping
Back sleeping ought to begin when your newborn initially sleeps and persists until they become capable of independently rolling from their back to belly and vice versa, usually between 6 months. Even when your baby acquires the art of rolling over, always initially put them onto their back. If they do roll over at night, do not turn them over after that when they possess this ability.
How to Put a Newborn to Sleep
Putting your newborn to sleep involves more than just laying them down in their crib. Successful baby sleep relies on establishing helpful routines and recognizing sleep cues. Newborns sleep a lot—typically 14-17 hours per day—but only in short stretches of 2-4 hours at a time. Following a consistent approach can help your baby fall asleep more easily and develop healthy sleep associations from the start.
1. Identify Sleep Cues
Watch for sleep signs that show your baby is sleepy: slow movement, eye rubbing, yawning, looking away, or fussing. These will typically happen every 45-90 minutes in newborns. Identifying early tiredness can prevent overtiredness, leading to babies fighting sleep more. A sleepy baby who is not placed down sooner will become cranky and have more trouble sleeping.
2. Set Up a Calming Environment
Create a sleep-friendly space with dimmed lights, comfortable temperature (68-72°F), and reduced noise. The Momcozy Smart Baby Sound Machine offers 34 high-fidelity sounds—including white noise, lullabies, and nature sounds—that effectively block household noises while mimicking the soothing whooshing sounds babies heard in the womb. Its adjustable LED lamp provides a gentle glow in seven different colors, creating the perfect sleep ambiance. You can easily control settings through the app or with a simple touch, adjusting volume and brightness based on your baby's preferences. Close curtains or blinds to darken the room, especially for daytime naps, and avoid bright screens before sleep time to signal it's time to rest.
3. Manage the Feeding-Sleep Connection
Most babies become sleepy during feeding, and this is normal. For breastfed babies, nurse until sleepy but not asleep. Bottle-fed infants should be sat up for 15-20 minutes after feeding to help digest and relieve reflux discomfort. If your baby gets asleep during feeding, wake him or her up a little before putting him or her down in his or her crib—this helps him, or she learn to fall asleep in his or her sleeping spot rather than always his or her arms.
4. Use The Gentle Transfer Technique
When moving your drowsy baby to their crib or bassinet, use slow, steady movements. Keep your baby close to your body as you lower them down. Place their feet at the foot of the crib first, then slowly lower their body and head last. Maintain contact with one hand on their chest and one hand under their neck before fully withdrawing your hands. After the transfer, the Momcozy 5-Inch Smart Baby Monitor provides peace of mind with real-time motion alerts and crying detection, allowing you to monitor your baby without disturbing them. Its two-way talk feature lets you softly reassure your baby with your voice if they stir, while the customizable safe zone alerts you if they move into an unsafe position. This gentle monitoring helps you respond appropriately without unnecessary interventions.
What Makes a Safe Sleep Environment for Your Baby?
Now that you know how to position your baby on their back and recognize when they're ready for sleep, creating a safe sleep space is your next priority. While the right sleep position dramatically reduces SIDS risk, the environment where your baby sleeps matters just as much. The American Academy of Pediatrics emphasizes that a proper sleep space can prevent suffocation, entrapment, and overheating—all factors linked to sleep-related infant deaths.
1. Create a Firm, Flat Sleep Surface
Your baby's mattress must be flat and firm without any incline. Soft surfaces form pockets in which a baby's face may sink, raising suffocation risks. Select a mattress made especially for cribs or bassinets that fits tightly against all four sides with no gaps. Avoid mattress toppers, memory foam, or pillow-like padding. The surface must not indent when your baby is placed on it. Always cover the mattress with a snug-fitting sheet that fits tightly over the corners without gathering. Playpens and portable cribs should only be used with the pad that comes with them—never add any additional cushioning underneath.
2. Keep the Crib Bare
Remove all loose items from your baby's sleep space. This means no pillows, blankets, stuffed animals, positioners, or bumper pads—even those marketed as "breathable." These items pose suffocation and strangulation hazards. Instead of blankets, dress your baby in a wearable blanket or sleep sack appropriate for room temperature. If you are concerned that your baby is cold, add a layer of clothing rather than covering your baby with loose bedding. The only thing in the crib is your baby on a firm mattress with a tight-fitting sheet.
3. Share Your Room, Not Your Bed
Have your baby's crib, bassinet, or portable crib in your room for at least the first 6 months, ideally the first year. Room sharing allows you to monitor your baby and respond to your baby's needs promptly while reducing SIDS risk by up to 50%. Do not bed share, however, since it increases the dangers of suffocation from soft adult bedding, potential overlying, and gaps between the mattress and headboard/wall. If you take the baby to bed with you to feed or comfort, return them to their own sleeping place prior to falling asleep yourself. An attached bedside bassinet can help with midnight accessibility.
4. Maintain an Ideal Temperature
Infants are less capable than adults at regulating their body temperature and can quickly overheat—a known risk factor for SIDS. Room temperature should be comfortable at 68-72°F (20-22°C). Check your baby's neck or chest (not hands or feet) to see if they're too hot; they should be warm but not sweaty. Dress your baby in one layer more than you'd wear to be comfortable. Avoid hats indoors and watch for signs of overheating like rapid breathing, flushed cheeks, heat rash, or irritability. Circulate the air within the room using a fan, but avoid aiming it at your baby.
What Should You Do When Your Baby Won't Settle?
Even with a perfect sleep setup, some nights your baby just won't settle down. Having a safe crib and the right room temperature doesn't guarantee peaceful sleep—many babies have physical discomforts or simply haven't adjusted to normal sleep cycles yet. Don't worry—you're not doing anything wrong. About 1 in 4 babies have sleep troubles in their first year. Knowing why your baby might be fussy can help you comfort them more effectively.
1. Recognize Colic and Gas Issues
If your infant cries relentlessly for several hours at least three days a week, they probably have colic—which affects so many newborns. Look for signs like legs being pulled up, back being arched, or fists curled. To calm gas, use bicycling motion on their legs, rub belly, or hold them upright following feeding. Burp them lots during and after feeding. All babies outgrow colic between 3-4 months, so these horrible nights won't last forever.
2. Treat Reflux Symptoms
When stomach contents back up and are uncomfortable, that's reflux—something nearly half of all babies experience. Watch for copious spit-ups, arching during feeding, fussing after feeding, or staying awake at night. Hold your baby up for 20-30 minutes after feeding and attempt to give smaller and more frequent feedings. For bottle-fed babies, ensure the nipple flow is adequate for your baby. Speak with your doctor if reflux is excessive or affects your weight gain.
3. Prevent Overtiredness
Surprisingly, very sleepy babies resist sleep more. Their bodies release stress hormones that hinder relaxation. Watch for early signals of fatigue and get your baby into bed before irritability. Newborns typically need sleep after just 45-60 minutes of wakefulness. Create a simple, consistent bedtime routine that signals the baby's sleep time is coming. Place an already overtired infant in a quiet, dark area and try to hold them until they become relaxed.
4. Reset Day/Night Confusion
Newborns don't inherently know day from night—they just spent months in perpetual darkness! Teach them by making days bright and stimulating and nights dark and dull. At nighttime feedings, use dim light and no playtime. Most babies start developing improved sleep habits around 6-8 weeks, with larger gains by 3-4 months.
When Should You Seek Expert Advice?
While many sleep challenges resolve with time and home strategies, sometimes your baby's sleep issues might signal something that needs medical attention. After having worked through the measures to address colic, reflux, overtiredness, and day/night reversal, you may discover certain problems persisting beyond what you define as normal. If you're unsure whether your newborn's behavior is normal, ask a pediatrician or sleep consultant for advice.
1. Your baby is having difficulty breathing, is turning blue or purple, or is making strange sounds during sleep that may indicate a breathing problem.
2. Refeeding is consistently difficult due to excessive crying, arching, or refusal that cannot be managed by basic reflux therapy.
3. Your baby is too sleepy, difficult to wake up for a feeding, or sleeps through feedings to have fewer than 8 feeds in 24 hours.
4. Sleep issues are also accompanied by poor weight gain, with your baby not gaining birth weight by two weeks or gaining less than recommended at check-ups.
5. Your baby experiences projectile vomiting (forceful vomiting that shoots several inches) after feeds rather than normal spitting up.
6. Your baby cries for more than three hours a day for more than three weeks, regardless of what you do to try and comfort them.
7. Your baby seems stiff or floppy when held or placed in a sleeping position.
8. Your baby has developed a flat area at the back of their head (positional plagiocephaly) due to sleeping in the same position all the time.
9. The whole family is suffering from exhaustion or postpartum depression symptoms due to chronic sleep disturbances.
10. Your parent's gut feeling just tells them something is not right, although you may not be able to put your finger on what that might be.
FAQs About How to Lay a Newborn to Sleep
Q1: What is the best position for a newborn to sleep?
Always put your baby to bed on their back, every time, until their first birthday. Sleeping on the back lowers the risk of SIDS by over 50%, and it doesn't raise the risk of choking—babies' airways are designed to clear fluid in this position. When babies are able to roll both ways unassisted (typically 4-6 months), you don't need to turn them over if they roll in the night.
Q2: What if baby doesn't burp and falls asleep?
If your baby is getting sleepy while feeding and refuses to burp after 5 minutes of gentle patting, simply place them on their back in their safe sleep area. Most newborns do not always need to be burped, particularly breastfed babies who tend to swallow less air. If your baby seems satisfied, there is no need to wake them up just for a burp. For babies with gas or reflux, try keeping them upright on your shoulder for 10-15 minutes before putting them to bed.
Q3: Why is it harder to put newborn to sleep at night?
Newborns have poorly developed circadian rhythms and do not yet secrete melatonin on a regular cycle. The majority of babies are at their most irritable (so-called "the witching hour") in the late evening hours due to overstimulation, overtiredness, or cluster feeding needs. Your baby also senses your own fatigue and possible stress after a long day. Reliable day/night signals, early bedtime routines, and restricted evening stimulation assist babies in developing more regulated sleep patterns over time.
Q4: What is the 15 minute rule for baby sleep?
The 15-minute rule is to wait for a short period before responding to nighttime fussing to see if your baby can settle by himself. For babies under 2 months, wait just 2-3 minutes before checking since they need to feed more often and be reassured. For older babies (3+ months), you may wait 10-15 minutes when they are making the softer fussing sounds—not full crying—to see if they are just flipping through sleep cycles. Always respond immediately to actual crying or distress, regardless of timing.
