When your baby’s fussy and sleep feels out of reach, a pacifier might feel like magic. But is it okay to let them fall asleep with it? The answer is yes—with a few safety-first considerations.

Let’s break down what the research says and how to use pacifiers thoughtfully as part of your baby’s sleep routine.

Key Takeaways

• Short answer? Yes - babies can sleep with a pacifier. 

• Pacifiers encourage non-nutritive sucking that improves sleep quality, comforts them and reduces oral aversions. 

• Pacifiers are linked to a reduced risk of SIDS when used during sleep.
  

• Choose the right pacifier—age-appropriate, one-piece, and BPA-free.
  

• Watch for signs of pacifier dependency as your baby grows.

• Talk to your pediatrician for personalized recommendations.

Pacifiers and Sleep: How They Help

That rhythmic sucking? It’s more than soothing. It triggers calming hormones in your baby’s brain and helps ease them into sleep—especially during times of transition like growth spurts or nap routine changes.

Pacifiers may:

• Encourage relaxation
  

• Provide a consistent source of comfort
  

• Support your baby’s ability to settle at bedtime
  

And for parents? A few more peaceful moments to catch your breath.

Potential Downsides to Keep in Mind

While pacifiers offer many sleep-friendly benefits, there are a few things to watch for:

• Frequent night wakings if the pacifier falls out and your baby can’t replace it on their own (yet!)
  

• Over-reliance, where baby struggles to sleep without it
  

• Higher risk of ear infections after 6 months of age
  

As with all things sleep—balance and observation are key.

 

Safety Tips for Pacifier Use

Choosing the Right Pacifier:

• Look for a one-piece design (no detachable parts)
  

• Use BPA-free materials
  

• Choose the right size for your baby’s age
  

• Check for a firm shield with ventilation holes to allow airflow
  
  

Important Reminders:

• Never tie a pacifier to a crib, blanket, or your baby’s clothing
  

• Plush pacifier holders should be small and lightweight, and should not be used during unsupervised sleep
  

• Encourage gradual self-soothing over time

• Flat or bulb-shaped pacifiers are more commonly linked to dental issues with prolonged use. Ideally, you want a pacifier that closely mimics the natural shape of your nipple to support oral development. Consult your pediatrician if you have questions!

Try: Limiting pacifier use to sleep times once your baby is older, to help reduce dependency.

Pacifiers and SIDS: What the Research Says

Can newborns sleep with a pacifier?
Yes—with a few key guidelines.

One of the strongest reasons parents choose to offer a pacifier during sleep? Its association with a reduced risk of Sudden Infant Death Syndrome (SIDS).

Although researchers don’t fully understand why, it’s believed pacifiers may help:

• Keep the airway open
  

• Support lighter sleep, making arousal easier
  

• Position the tongue forward, reducing airway obstruction
  

Good to know: If your baby falls asleep with the pacifier and it drops out—that’s okay. You don’t need to put it back unless they wake up and need help settling.

 

Pacifiers and Newborn Feeding

Can you use a pacifier if you’re breastfeeding?  Yes!

If you’re breastfeeding and concerned about the potential of nipple confusion with pacifier usage, research shows that nursing moms who introduce a pacifier are JUST as successful with nursing as those who don’t. True scientific research dispels the myth of nipple confusion and shows that limiting pacifiers does not increase nursing success. 

Pacifier and feedings? Using a pacifier can delay feedings or skip a feeding altogether. Always offer your milk first before the pacifier. If your baby has low or slow weight gain, pacifier use may not be appropriate.

Still, every baby is different. If you’re having challenges, connect with a lactation consultant or your pediatrician to make a plan that works for you.

 

Managing Pacifier Dependency

Pacifiers are meant to help—not create new sleep hurdles.

Watch for signs your baby may be too reliant:

• Needs the pacifier all day, not just for sleep
  

• Can’t fall asleep without it
  

• Wakes multiple times a night when it falls out
  

• Gets upset when it’s taken away, even briefly

 

How to Wean Off the Pacifier

Weaning doesn’t have to be all-or-nothing. A gradual approach works best.

Try:

• Limiting use to naps and bedtime only
  

• Offering comfort alternatives (snuggles, a favorite toy)
  

• Celebrating progress with praise or small rewards like a sticker chart
  

Consistency helps, especially during transitions.

Soothing Alternatives to Pacifiers

When it’s time to wean—or if pacifiers just aren’t your baby’s thing—there are other ways to bring calm:

• Comfort objects: A breathable lovey or blanket (once your baby is old enough)
  

• Soothing activities: Rocking, singing, or a gentle bedtime routine
  

• Your voice and touch: Often, your presence is the most reassuring tool you have
  
  

Note: Some babies turn to thumb-sucking in place of pacifiers. That’s okay for now—focus on the pacifier transition first, and revisit thumb habits later if needed.

 

When to Replace a Pacifier

Pacifiers don’t last forever. Keep an eye out for:

• Cracks or tears
  

• Sticky texture after washing
  

• Discoloration or thinning
  

Even if it looks okay, aim to replace every 4–6 weeks, or sooner if you notice wear.

Final Thoughts

Pacifiers can be a comforting part of your baby’s sleep journey. They may even support safer sleep by reducing the risk of SIDS. If your baby finds comfort in one, and you’re following safe use guidelines, know that you’re making a thoughtful choice.

Some babies love pacifiers. Some never take to them. Others grow out of them before you’re ready.

Whatever your journey looks like—you’re doing an amazing job.
