Key Takeaways:
Inclined bassinets are not considered safe for infants due to the increased risk of SIDS. The incline can cause babies to roll into unsafe positions. This can block their airways and pose serious safety risks. Use bassinets on flat, stable surfaces per the manufacturer’s sleep-safety guidelines.

For years, inclined bassinets have been a favorite among parents who believe they help soothe fussy babies and reduce acid reflux.
Many caregivers swear by their ability to help little ones sleep faster and more soundly.
But what if the product designed to comfort infants puts them at risk?
In recent years, safety concerns surrounding inclined sleepers have led to major recalls, urgent warnings from pediatricians, and alarming reports of infant injuries and deaths.
So, what changed? Why were inclined bassinets once considered a must-have, only to now be labeled as dangerous?
Before putting your baby in an inclined sleeper, let’s look at the research, expert advice, and real risks every parent should know.
Are Inclined Bassinets Safe for Newborns?
No, inclined bassinets are not safe for newborns due to the risk of suffocation and Sudden Infant Death Syndrome (SIDS). The incline can cause babies to roll into dangerous positions, making it difficult for them to breathe.

Pediatricians and the American Academy of Pediatrics (AAP) strongly recommend using a flat, firm sleep surface with no incline over 10 degrees to ensure infant safety.
But what exactly makes inclined bassinets so dangerous?
Back in 2015, inclined sleepers were marketed as a ‘solution’ for reflux, and many doctors didn’t see an issue.
But as more studies emerged, we realized the dangers were far greater than the supposed benefits. Now, experts unanimously agree that a flat surface is safest.
Aspect | Pre-2018 Beliefs (Before Research & Recalls) |
---|---|
Marketing Claims | Advertised as a solution for acid reflux & colic |
Pediatrician Advice | Some doctors recommended inclines to help with reflux |
Regulations | No federal bans or strict safety regulations were in place |
Parental Perception | Parents believed babies slept longer in inclined sleepers |
Manufacturer Warnings | Minimal warnings—products were considered safe |
Incline Safety Studies | Limited research on rolling risks & airway obstruction |
A tragic case in 2018 highlighted the risks of inclined bassinets. A New York parent filed a complaint with the Consumer Product Safety Commission (CPSC) after their 6-month-old tragically died while sleeping in a Fisher-Price Rock ‘n Play sleeper (WSJ Report).

At the time, the CPSC suspected inclined bassinets could cause suffocation. But as more cases emerged, it became clear that babies rolling over in these sleepers faced serious dangers.
On May 31, 2018, the CPSC issued a consumer alert, urging parents to use restraints when placing babies in inclined bassinets. However, this did not eliminate the risk.
CPSC Official Statement (2018):
“CPSC is aware of infant deaths associated with inclined sleep products. Babies have died after rolling over in these sleep products. CPSC, therefore, urges consumers: Always use restraints and stop using these products as soon as an infant can roll over.”
(CPSC Announcement)
But here’s the problem: There is no set age when a baby starts rolling over. Some babies begin rolling as early as 3 months, while others take longer.
My own son didn’t start rolling until he was almost seven months old! This unpredictability makes inclined bassinets even more dangerous, as parents may not realize the risk until it’s too late.
The CPSC wanted to understand why inclined bassinets are unsafe, so they hired Erin Mannen, Ph.D., a biomechanics expert, to study how these products affect infants.
🧠 Dr. Erin Mannen’s Research:
“We found evidence that some of the deaths linked to these products occurred when babies who were placed on their backs to sleep rolled over—many for the first time—and were found dead on their stomachs.”
(University of Arkansas Medical Sciences Study)
Why Does This happen?
- Inclined surfaces make it easier for babies to roll over but nearly impossible to roll back
- Soft padding and slopes restrict movement, increasing the risk of suffocation
- Babies’ neck muscles are underdeveloped, making it harder for them to lift their heads when facedown

Dr. Mannen also studied inclined bassinet mattresses, pillows, and wedges—and confirmed that these increase the danger even more.
By 2019, the CPSC and pediatric safety organizations concluded that inclined bassinets were too dangerous. On October 31, 2019, they issued a clear warning:
🚨 CPSC Alert: Stop using inclined sleepers immediately!
Recalled Inclined Bassinets:
- Fisher-Price Rock ‘n Play Sleeper (Recalled in 2019)
- Kids II Rocking Sleeper (Recalled in 2019)
- Eddie Bauer Slumber and Soothe Rock Bassinet (Recalled)

Present (2025): Inclined Bassinets Are Officially Deemed Unsafe!
After years of studies, recalls, and tragic incidents, inclined bassinets are now officially deemed unsafe.
Aspect | Current Understanding (Post-2018 Research & Recalls) |
---|---|
Scientific Research | Studies show babies can roll over & suffocate |
CPSC Findings | Over 100 infant deaths linked to inclined sleepers |
Pediatrician Advice | AAP & doctors strongly warn against them |
Legal Actions | Banned under the 2022 Safe Sleep for Babies Act |
Parent Perception | Many parents stopped using them after recalls & warnings |
Current Recommendation | Babies should ONLY sleep on a flat, firm surface |
📢 Safety Reminder: Just because something is still sold in stores doesn’t mean it’s safe. Always check recall lists and follow the latest pediatric guidelines.
It’s time to rethink baby sleep safety. Inclined bassinets may once have seemed helpful, but today’s research makes it clear: a flat, firm sleeping surface is the only safe option.
Can Newborns Sleep on an Incline? Is it Safe?
No, it’s not safe for newborns to sleep on an incline.
🧠 Dr. Erin Mannen’s research found that babies in inclined sleepers often roll over for the first time while in the product—leading to a risk of fatal suffocation.

This highlights why some parents think their baby is safe… until it’s too late. Pediatricians now stress that even small inclines can be dangerous since a newborn’s head control is still underdeveloped.
However, Dr. Mannen did clarify that if an incline is medically necessary, it should:
- Never exceed 10 degrees
- Be paired with a flat, rigid sleeping surface (not soft or plush)
🧠 Dr. Mannen’s Study Findings:
“The safest sleep environment for infants is a flat, firm surface. Inclined surfaces, even at lower angles, can make it easier for babies to roll over, increasing suffocation risk.”
Key Takeaways:
- The safest sleep setup is flat & firm—no soft padding, pillows, or wedges
- If an incline is needed for medical reasons, keep it below 10 degrees
- Babies start rolling between 4–6 months, increasing the risk with any incline
- Always move your baby to a crib before they begin rolling
👩👧 Real Mom Tip (via BabyCenter):
“I believe that the most up-to-date research shows that there’s no danger to babies spitting up while sleeping flat, so if I were you, I wouldn’t risk raising her.” (BabyCenter Discussion)
💡 Even at a slight incline, newborns are safer on a completely flat surface. If you’re worried about reflux, there are safer ways to help your baby sleep better—more on that in the next section!
Incline vs. Flat – Which One Is Better?
When it comes to newborn sleep, the flat sleep surface wins—every time.
Factor | Inclined Bassinet 🚫 | Flat Bassinet/Crib ✅ |
---|---|---|
Safety | Unsafe—risk of rolling & suffocation | Safest sleep position |
SIDS Risk | Higher risk—linked to infant deaths | Strongly reduces SIDS risk |
Breathing & Airway Safety | Can block airways, making breathing difficult | Keeps airways clear, natural gag reflex works |
Rolling Over Risk | Easier for the baby to roll into an unsafe position | Lowers the risk of accidental rolling |
AAP & Pediatrician Approval | NOT recommended—CPSC & AAP advise against it | Strongly recommended by all pediatricians |
Best Sleep Environment | Marketed for reflux but has no proven benefits | A flat, firm mattress ensures safe sleep |
💡 Final Thought: The inclined bassinet may sound helpful, but science proves otherwise. Flat and firm is not just preferred—it’s life-saving.
How To Elevate Bassinet for Reflux Safely?
Many parents turn to inclined bassinets hoping to ease acid reflux or spit-up in newborns. But here’s the truth—research doesn’t support this.

👩⚕️ Dr. Florencia Segura, Pediatrician:
“There is no substantial evidence that an inclined bassinet helps with reflux. In fact, it has no effect on reflux and also risks the infant sliding into an unsafe sleep position.” (Source)
So why do hospitals sometimes use inclines? In medical settings, inclined positioning is closely monitored and used only for babies with specific health conditions—not something meant for at-home use.
A newborn needs around 16 hours of sleep per day, and keeping that sleep safe and flat is crucial for their development and well-being.
📢 CPSC Reminder: Bassinets, cribs, and play yards should always be used on a flat, firm surface. If an incline is medically necessary, follow these strict safety guidelines:
- Use a minimal incline (no more than 8–10 degrees)
- Ensure the bassinet surface stays firm and flat even at an angle
- Remove loose bedding, pillows, toys, or wedges—they increase suffocation risk
Safe Alternatives to Bassinet Inclines for Reflux Relief:
- Hold your baby upright for 20–30 minutes after feeding before laying them down
- Offer smaller, more frequent feeds to reduce reflux
- Try anti-colic or slow-flow bottles to minimize swallowed air
- Include supervised tummy time during the day to aid digestion
💡 Follow the AAP’s ABCs of Safe Sleep:
- A – Baby sleeps Alone (no loose items in bed)
- B – Baby sleeps on their Back
- C – Baby sleeps in a Crib (or bassinet) with a flat, firm mattress
Frequently Asked Questions
Q: Why Are Hospital Bassinets Angled?
Hospital bassinets are slightly angled to help clear mucus from a baby’s airways, especially for newborns with breathing issues. However, these settings are monitored by medical professionals and are not meant for home use.
Q: Why Can’t Babies Sleep With Their Heads Elevated?
Elevating a baby’s head during sleep can cause their chin to fall toward the chest, which may block the airway and increase the risk of SIDS and suffocation. That’s why flat sleeping is always safest.
Q: Is It Safe to Prop Up a Bassinet?
No, propping up a bassinet is unsafe. It increases the chance of rolling, sliding, and suffocation. Always follow the manufacturer’s instructions and keep it flat unless medically directed.
Q: Can You Put a Bassinet on an Angle?
No, placing a bassinet on an angle increases the risk of SIDS and breathing difficulties. The surface should always be flat and stable to support safe sleep.
Q: Is It Safe to Use a Bassinet Wedge?
Bassinet wedges are not safe. They create an incline that can lead to unsafe sleep positions or blocked airways. Always talk to a pediatrician before adding any accessory to your baby’s sleep area.
Q: Is It Safe to Incline a Next-to-Me Crib?
No, inclining a next-to-me crib is also unsafe. Even a slight tilt can cause babies to roll into dangerous positions. Always use it flat and level, as per safety guidelines.
Q: Is an Inclined Bassinet Safe for Reflux?
Inclined bassinets are not a safe solution for reflux. The AAP recommends flat sleep surfaces, and there’s no scientific proof that inclines help with reflux. Safer reflux alternatives are available and recommended.
Q: Do Babies Sleep Better Flat or Inclined?
Babies sleep safest on a flat surface. While some parents believe an incline helps with reflux, studies show it can be dangerous and increase SIDS risk. Flat is always best.
