Quick Answer
Yes—when used correctly, pacifiers are considered safe and may reduce SIDS risk. AAP safe sleep guidance recommends offering a pacifier at nap time and bedtime. For breastfed babies, wait until breastfeeding is well established—usually about 3 to 4 weeks. Never tie a pacifier to the crib, neck, or hand. If it falls out after sleep begins, you do not need to replace it.
What Parents Need to Know
Pacifiers can soothe babies and worry parents in equal measure. Families ask whether pacifiers interfere with breastfeeding, damage teeth, or create sleep crutches.
AAP and CDC guidance treats pacifiers as a sleep-safety tool when used with a bare crib, back sleeping, and room sharing without bed sharing. They are optional—some babies refuse them, and that is fine.
Evidence-Based Guidance
AAP safe sleep policy on HealthyChildren.org recommends giving your baby a pacifier at nap time and bedtime to help reduce the risk of SIDS, even if the pacifier falls out after your baby falls asleep.
For breastfed infants, AAP guidance says to wait until breastfeeding is well established before offering a pacifier. That usually means good milk supply, comfortable feeds, effective latch, and appropriate weight gain—often around 3 to 4 weeks. If you are not breastfeeding, you may introduce a pacifier when you choose.
AAP guidance also notes:
- Do not force a pacifier if baby refuses.
- Do not hang a pacifier around baby's neck or attach it to clothing during sleep.
- You do not need to put the pacifier back once baby is asleep.
AAP pacifier safety guidance adds practical rules:
- Do not use a pacifier to replace or delay feeds.
- Never tie a pacifier to the crib, neck, or hand—strangulation risk.
- Choose a one-piece model with a shield at least 1½ inches across and air holes.
- Do not use a bottle nipple as a pacifier.
- Clean pacifiers before early use and replace worn ones.
CDC SIDS guidance for parents and caregivers also lists pacifier use at sleep time among strategies to reduce SIDS risk, alongside back sleeping, room sharing, avoiding smoke exposure, and breastfeeding when possible.
Practical Steps
- Establish breastfeeding first if nursing—then offer pacifier at sleep times if desired.
- Offer at nap and bedtime, not to stretch feeds.
- Use a one-piece pacifier with a wide shield; skip homemade substitutes.
- Keep the crib bare—no strings, clips, or attached toys.
- Wean pacifier use gradually after age 1 if your pediatric dentist advises—prolonged use past 2 to 4 years may affect teeth alignment per AAP guidance.

When to Contact a Clinician
Contact your pediatrician if:
- Breastfeeding becomes painful or supply drops after pacifier introduction
- Your baby refuses feeds but sucks only on a pacifier
