When you become a parent, sleep can suddenly feel stressful. Many caregivers find themselves checking on their baby multiple times a night, watching their chest rise and fall just to be sure everything is okay.
One surprisingly simple tool recommended by pediatric experts may help reduce some of that worry: using a pacifier during sleep.
Research has consistently shown that offering a pacifier at nap time and bedtime is associated with a reduced risk of Sudden Infant Death Syndrome (SIDS). While a pacifier isn’t a guarantee against SIDS, it is one of the few interventions supported by strong research.
Do Pacifiers Reduce the Risk of SIDS?
Yes. Research shows that offering a pacifier at nap time and bedtime is associated with a 50–90% reduction in Sudden Infant Death Syndrome (SIDS) risk. Because of this evidence, the American Academy of Pediatrics recommends offering a pacifier during sleep as part of safe sleep practices for infants. (Learn more about the research)
Large population studies and meta-analyses consistently show that babies who use a pacifier during sleep have a significantly lower risk of SIDS compared with babies who do not.
The American SIDS Institute also includes pacifier use on its list of recommended ways to reduce the risk of sudden infant death.
While pacifiers cannot eliminate risk entirely, they are widely considered one helpful tool within a broader safe sleep strategy.
Why Might Pacifiers Help Protect Babies During Sleep?
Researchers still do not know the exact reason pacifiers appear to reduce SIDS risk, but several evidence-supported theories exist.
Pacifiers May Help Keep the Airway Open
The sucking motion created by a pacifier may help stabilize a baby’s tongue and jaw position, which could help keep the airway more open during sleep.
Pacifiers May Encourage Lighter Sleep
Some researchers believe pacifiers may help babies remain in slightly lighter sleep states. This could make it easier for babies to wake or adjust their breathing if something becomes irregular.
Pacifiers May Influence Sleep Position
Pacifiers may also influence how babies position their tongue or head during sleep, which may improve airflow.
Although the exact mechanism is still being studied, the protective association between pacifiers and SIDS has been observed repeatedly in large studies.
Pacifiers Do Not Replace Safe Sleep Practices
A pacifier should always be used alongside safe sleep guidelines, not instead of them.
The safest sleep environment for babies includes:
• Placing babies on their back for every sleep
• Using a firm, flat mattress in a safety-approved crib or bassinet
• Keeping the sleep space free of loose blankets, pillows, toys, and bumpers
• Avoiding cords, clips, or attachments connected to pacifiers during sleep
Pacifiers can be a helpful addition, but the sleep environment itself remains the most important factor in safe sleep. Learn about how to set up a safe sleep environment.
When Should You Introduce a Pacifier?
Parents often wonder when it is safe to introduce a pacifier.
For families who are breastfeeding, many pediatric experts recommend waiting until breastfeeding is well established, which usually happens around 3–4 weeks of age.
This helps reduce the chance of early feeding confusion.
Additional safe pacifier tips include:
• If your baby refuses a pacifier, don’t force it
• If the pacifier falls out after your baby falls asleep, you do not need to replace it
• Replace pacifiers regularly to maintain hygiene and safety
• Choose pacifiers designed specifically for infants
Choosing a Pacifier Designed With Safety in Mind
Because babies may use pacifiers for hours each day, the materials and safety standards behind them matter.
The Soothe Beginnings Pacifier Kit was designed to address many of the concerns parents have about pacifier safety and durability.
Every Batch Is Tested for Safety
Their pacifiers are PFAS-tested with every production batch, not just once per year. Many brands test occasionally, but consistent testing provides parents with stronger reassurance.
Latex-Free and Hypoallergenic
The nipples are made from medical-grade silicone, which avoids the allergy concerns associated with latex and resists the breakdown that can occur with porous materials.
Plastic-Free and Eco-Friendly
Instead of traditional plastic shields, their pacifier uses a Richlite® shield made from sustainable materials that are Greenguard Gold Certified. This creates a durable pacifier while reducing reliance on petroleum-based plastics.
A 3-in-1 System That Saves Parents Time and Money
Many parents end up buying several pacifiers before finding one that their baby accepts. The Soothe Beginnings Pacifier Kit includes three nipple shapes, allowing babies to naturally choose what feels most comfortable. This simple design helps reduce the trial-and-error parents often experience when searching for the right pacifier.
Convenience Without Compromise
Pacifier shields can also be personalized with your baby’s name, making them easy to identify at daycare while also creating a keepsake many parents hold onto long after the newborn stage. Parents shouldn’t have to choose between peace of mind and convenience. The two should go hand in hand.
Why Many Parents Check Their Baby’s Breathing at Night
Even when babies are sleeping safely, many parents find themselves repeatedly checking their baby’s breathing.
This instinct is incredibly common, especially in the early months when the risk of SIDS is highest. Pediatric researchers often refer to this as normal parental vigilance, but for some families, it can turn into frequent nighttime checking that disrupts sleep.
Using tools recommended by pediatric experts, like safe sleep practices and offering a pacifier at bedtime, can help parents feel more confident about their baby’s sleep environment.
Sleep of Mind Breathing Reassurance sleepwear can also be a game-changer for anxiety levels. It's award-winning design makes it easy to see your baby breathing on any night vision baby monitor. Any time you feel like checking, all you have to do is turn your baby monitor on and instantly you'll see the "shimmer" effect as your baby takes each breath, regardless of what position they're sleeping in.

The Bottom Line: Pacifiers Are a Simple Tool That May Reduce SIDS Risk
Pacifiers are often thought of as soothing tools, but research suggests they can also support safer infant sleep. While scientists are still studying exactly why pacifiers appear protective, the evidence consistently shows that offering a pacifier at nap time and bedtime may reduce the risk of SIDS when used alongside safe sleep practices. For many families, that small step can provide meaningful peace of mind during the early months of parenting.
Frequently Asked Questions About Pacifiers and SIDS
If the pacifier falls out during sleep, should I put it back?
No. If your baby falls asleep and the pacifier naturally falls out, there is no need to replace it. The protective effect appears to come from offering the pacifier at sleep onset.
What age should babies stop using a pacifier?
Most pediatric experts recommend limiting pacifier use after age one and gradually phasing it out between 12–18 months to support healthy dental and palate development.
Do pacifiers interfere with breastfeeding?
Pacifiers can sometimes interfere with breastfeeding if introduced too early. Many experts recommend waiting 3–4 weeks, once breastfeeding is well established.
Are silicone pacifiers safer than latex pacifiers?
Silicone pacifiers are often preferred because they are latex-free, non-porous, durable, and less likely to cause allergic reactions.
