Pacifiers seem simple until you're standing in front of dozens of shapes, sizes, and materials, and your baby only likes one of them. Here's what actually matters when choosing one, a real safety benefit worth knowing about, and a look at two pacifiers MacroBaby carries.
Silicone vs. natural rubber (latex)
Silicone pacifiers are durable, hold their shape well, and are easy to sanitize since they don't absorb odors or degrade quickly with repeated boiling or dishwasher cycles. Natural rubber (latex) pacifiers are softer and more flexible, closer to the texture of skin, which some babies prefer, though they wear out faster and need more frequent replacement. Neither material is objectively better, it often comes down to which one your specific baby accepts.
What does "orthodontic" actually mean?
An orthodontic pacifier has an asymmetrical, flattened nipple shape designed to leave more room for a baby's natural sucking motion and reduce pressure on the roof of the mouth and teeth, compared to a traditional round nipple. Brands vary in how they execute this: some flatten the bottom of the nipple, others round it differently on top versus bottom. This is a shape difference, not a restriction on which way the pacifier can be used, an orthodontic pacifier still works right side up or upside down; the asymmetry is about the nipple's profile, not a rule about orientation.
Sizing by age
Pacifiers are grouped by age range because the nipple size and shield are built to match how a baby's mouth grows. Most brands split this into groups like 0 to 3 months, 3 to 6 months, and 6 to 18 months, with some using broader 0 to 6 month and 6 to 18 month groupings. Using a nipple sized for an older baby can be too large or firm for a newborn's mouth, and using one sized too small for an older baby doesn't give enough resistance for a stronger, more developed suck.
The safety benefit most parents don't know about
This is worth knowing plainly: the American Academy of Pediatrics recommends offering a pacifier at naptime and bedtime specifically because it's associated with a meaningfully reduced risk of Sudden Infant Death Syndrome. A large meta-analysis found pacifier use during sleep was associated with roughly a 50 to 60 percent reduction in SIDS risk, and the protective effect persists even after the pacifier falls out of the baby's mouth, so there's no need to reinsert it once they're asleep. For breastfed babies, the AAP recommends waiting until breastfeeding is well established, generally around 3 to 4 weeks, before introducing a pacifier, since earlier introduction has been linked to shorter breastfeeding duration in some studies. Babies who are not breastfeeding can start whenever it's convenient.
Safety rules that matter
- Never attach a pacifier to a cord, string, or ribbon around your baby's neck or clothing, this is a documented strangulation risk, especially during sleep.
- Don't attach stuffed animals, plush toys, or other soft objects to a pacifier, these add suffocation and choking risk.
- Never coat a pacifier in honey or other sweet liquids to encourage acceptance, honey specifically carries a botulism risk for infants under 1 year.
- Don't force a pacifier on a baby who refuses it, some babies simply don't take to them, and that's fine.
- Check the nipple regularly for tears, stickiness, or cracks, and replace it if you notice any damage.
Our picks: what MacroBaby carries
The Philips Avent Soothie is the same pacifier used by medical professionals in hospitals nationwide to calm newborns, made from BPA-free, medical-grade silicone in a one-piece design with no separate parts to trap moisture. For babies with more sensitive skin, the MAM Air uses large open-air holes around the shield to maximize airflow to the face, paired with an orthodontic silicone nipple, and is sized for the 6 to 16 month range.
Keeping track of pacifiers
Pacifiers are notorious for getting lost, dropped, or left behind, so it's worth having several on hand for each age stage rather than relying on just one or two. Pacifier clips that attach to clothing (without attaching the pacifier itself to a cord around the neck), a portable pacifier case to keep a spare clean in a diaper bag, and a dedicated pacifier wipe or sanitizer for on-the-go cleaning after a floor drop all make daily life easier.
When to start weaning
Most pediatric dental guidance recommends weaning off a pacifier somewhere between age 2 and 4, since prolonged use past that window is more likely to affect the alignment of the teeth and dental arch. The American Academy of Family Physicians also notes that weaning during the second six months of life can reduce the risk of ear infections (otitis media), though this is a separate consideration from the dental timeline. There's no single correct age, weaning gradually and consistently tends to work better than an abrupt cutoff.

Frequently Asked Questions
Does a pacifier really reduce the risk of SIDS?
Yes. The American Academy of Pediatrics recommends offering a pacifier at naptime and bedtime based on research showing a meaningful reduction in SIDS risk, and the protective effect continues even if the pacifier falls out during sleep.
When should I introduce a pacifier to a breastfed baby?
The AAP recommends waiting until breastfeeding is well established, generally around 3 to 4 weeks, since introducing a pacifier earlier has been linked to shorter breastfeeding duration in some studies. Non-breastfeeding babies can start anytime.
What does an orthodontic pacifier nipple actually do?
It uses an asymmetrical, flattened shape designed to leave more room for natural sucking and reduce pressure on the developing teeth and palate, compared to a standard round nipple. It can still be used in any orientation.
Is it safe to attach a pacifier to a string or clip?
Never attach a pacifier to a cord or string around your baby's neck or clothing, especially during sleep, since this is a documented strangulation risk. A pacifier clip that fastens to clothing without a long cord is a safer way to keep track of it.
When should my child stop using a pacifier?
Most pediatric dental guidance recommends weaning between age 2 and 4 to avoid effects on tooth alignment. Gradual weaning tends to work better than an abrupt stop.
