When it comes to safe sleep, parents want every tool possible to protect their baby. One of the simplest, evidence-based tools we have is the pacifier. Research shows that using a pacifier at nap time and bedtime can help reduce the risk of Sudden Infant Death Syndrome (SIDS)—but there are important details to know before you pop one into your baby’s mouth.

Do Pacifiers Really Reduce SIDS Risk?

According to the American Academy of Pediatrics (AAP) and the American Academy of Pediatric Dentistry (AAPD), offering a pacifier when putting a baby down to sleep is associated with a significant protective benefit. In fact, large studies and meta-analyses suggest pacifier use during sleep may reduce SIDS cases by as much as 50–90%.

The American SIDS Institute even includes pacifier use on their official list of ways to lower risk.

Why Does a Pacifier Lower Risk?

Here’s the honest answer: we don’t exactly know.
The link between pacifiers and reduced SIDS risk is consistent, but the exact reason isn’t proven. Experts have a few theories:

• Pacifiers may help keep a baby’s airway more open and stable.

• They might encourage lighter sleep, making it easier for a baby to arouse if needed.

• Pacifier use could influence head or tongue positioning during sleep.

These are well-supported hypotheses, but research is still ongoing. What’s clear is that pacifier use—paired with safe sleep practices—offers a real benefit.

Pacifiers Don’t Replace Safe Sleep

Here’s a critical reminder: a pacifier is not a magic fix. Adding one to an unsafe sleep environment does not cancel out the risks. Pacifiers only provide protection when safe sleep rules are followed:

• Always place baby on their back to sleep.

• Use a firm, flat mattress in a safety-approved crib or bassinet.

• Keep the sleep space free of soft bedding, pillows, bumpers, and toys.

• Never attach a pacifier to the crib, clothing, or around a baby’s neck.

When to Introduce a Pacifier

• If breastfeeding, wait until feeding is well established (usually 3–4 weeks) before introducing a pacifier.

• Don’t force your baby to take one if they refuse.

• Replace nipples on schedule to keep them safe and clean.

The Bottom Line

Pacifiers are more than just soothing tools—they’re one of the few interventions shown to consistently reduce the risk of SIDS when paired with safe sleep practices.

We may not fully understand why pacifiers work, but the evidence is strong: this simple habit can make a real difference in your baby’s safety.
