If you're wondering whether your little one can safely sleep with a pacifier, you're not alone. Many new parents have the same question, and the good news is that yes, babies can absolutely sleep with pacifiers, and it might even help keep them safer.

The research is clear on this one. The American Academy of Pediatrics actually recommends offering a pacifier at nap time and bedtime to reduce the risk of SIDS. But like everything with babies, timing and safety matter a lot.

benefits of pacifier use during sleep

SIDS protection that really works

Pacifiers can seriously reduce your baby's risk of Sudden Infant Death Syndrome (SIDS). Studies show that babies who use pacifiers during sleep have a 50-60% lower risk of SIDS compared to those who don't.

The cool part? Even if the pacifier falls out during sleep, your baby still gets the protective benefits. The initial sucking seems to trigger important safety responses in their little bodies.

better sleep for everyone

When baby sleeps better, everyone sleeps better. Pacifiers activate what's called the "calming reflex," helping babies self-soothe and drift off more easily.

Many parents notice longer sleep stretches and fewer middle-of-the-night wake-ups when introducing a pacifier to newborns for their sleep routines. The sucking motion also helps regulate breathing patterns and keeps their tongue in the right position.

beyond sleep benefits

Pacifiers aren't just for nighttime. They're lifesavers during fussy periods, doctor visits, and those mysterious crying spells that seem to have no cause.

the right way to introduce a pacifier

timing is everything

When introducing a pacifier, timing matters, especially for breastfed babies. If you're nursing, wait until breastfeeding is solid (usually around 3-4 weeks). This helps prevent any issues that could disrupt feeding.

Formula-feeding families can start right away if they want to.

choosing the perfect pacifier

Not all pacifiers are created equal. Here's what to look for:

• Age-appropriate sizing – Newborn pacifiers should be smaller and lighter
  
• One-piece construction – No extra parts that could break off and become a choking hazard
  
• Large shield – It should be too big to fit entirely in baby's mouth
  
• Ventilation holes - Located around the perimeter, these ensure compliance with federal consumer protection standards and provide airflow around baby’s mouth
  
• BPA-free, medical-grade materials – Always check the label.
  
• Breast-like design – A breast-like pacifier can help reduce nipple confusion for nursing babies
  
• *Easy Cleaning & Sterilization - The AAP recommends sterilizing pacifiers before each use. A pacifier that is dishwasher-safe makes this even more convenient and realistic (provided your dishwasher settings are hot enough)! 

*Before using, sterilize a new pacifier. Cleaning with soap and warm water is recommended regularly, especially if the pacifier is dropped or exposed to an unclean surface. If baby has been diagnosed with thrush or strep, pacifiers and bottle nipples should be sterilized daily:

• for thrush, as long as the mouth is infected
  
• for strep, as long as baby is on antibiotics.

Sanitizing wipes may be useful when soap and warm water are not available, but these should not be used in place of proper sterilization. For preemies and babies with compromised immune systems, consult your pediatrician.

why material matters: medical-grade silicone vs. natural rubber

Here's something many parents don't realize: the material your pacifier is made from can make a huge difference in performance and safety.

mōmi's pacifiers use medical-grade silicone, which maintains its shape and firmness throughout use. This means the nipple stays consistent, giving your baby the same comfortable sucking experience every time.

Many competitors use natural rubber, which sounds environmentally friendly and appealing. However, natural rubber tends to soften during use, especially as babies suck harder or longer. This collapse can frustrate babies and potentially interfere with the soothing benefits you're hoping for. 

Natural rubber pacifiers may trigger latex allergies and break down more easily. Medical-grade silicone, on the other hand,  resists bacteria and odors better than natural rubber, making it easier to keep clean and hygienic for repeated use.

safety first

Keep pacifiers squeaky clean by sterilizing new ones before first use. Soap and hot water (and then a thorough air-dry on a clean towel) is all that may be needed for maintenance with healthy, older babies. The AAP recommends sterilizing regularly to protect developing immune systems.

Replace any pacifier that shows cracks, tears, wear, or teeth marks. During illness, toss the old one and start fresh once baby feels better.

Never, ever attach strings, cords, clips, or even stuffed animals to baby’s pacifier during sleep. These are serious strangulation hazards.

what about breastfed babies?

Many nursing parents worry about using a pacifier, but research shows when you wait until breastfeeding is established, most babies handle both just fine.

When choosing the best breastfed newborn and infant pacifier, look for one that supports a healthy latch and proper tongue cupping, which are key elements of successful breastfeeding. Breast-like pacifiers reinforce natural nursing motions and can actually help maintain breastfeeding success. The mōmi pacifier is designed with these features in mind.

If you do notice any nursing issues after introducing a pacifier, consider taking a few days off with the pacifier or consulting with a lactation professional. Most problems resolve quickly.

the bottom line

Can babies sleep with a pacifier? Absolutely yes, and it's actually recommended by pediatric experts. The key is following safety guidelines, choosing the right products, and timing the introduction properly.

Every baby is different, so trust your instincts while following the science. With proper use, a nursing pacifier or regular pacifier can be a valuable tool for safer, more peaceful sleep.

frequently asked questions

What if My Baby Won't Take a Pacifier?
Not all babies accept pacifiers, and that's perfectly normal. Never force a pacifier on a baby who refuses it. Some babies prefer thumb sucking or other self-soothing methods. If your baby rejects pacifiers, they're still at low risk for SIDS when following other safe sleep guidelines.

Can Pacifiers Affect Breastfeeding Success?
When introduced at the appropriate time (after breastfeeding is established), pacifiers rarely interfere with nursing success. Some parents have reported that the mōmi pacifier has improved their baby’s breastfeeding skills by increasing their suck strength and helping their latch position.

How Often Should I Replace My Baby's Pacifier?
Replace pacifiers every 2-3 months during regular use, or immediately if you notice cracks, tears, or other damage. The silicone or latex can degrade over time, potentially creating safety hazards. Keep spare pacifiers on hand to ensure you always have clean, safe options available.

Is It Safe to Use Pacifiers for Premature Babies?
Pacifiers can be particularly beneficial for premature babies, helping with sucking reflex development and providing comfort during medical procedures. However, always follow your NICU team's guidance, as premature babies may have specific needs or restrictions regarding pacifier use.
