The best pacifier depends on your baby's age, sucking style, and skin sensitivity. Newborns generally do well with a one-piece silicone pacifier shaped like the one used in hospitals, such as the Philips Avent Soothie. Babies who prefer a softer, more flexible nipple often do better with natural rubber options like BIBS. Whatever you choose, always match the pacifier to your baby's current age range and replace it as soon as you see cracks, tears, or discoloration.
Picking a pacifier sounds simple until you're standing in the aisle facing a dozen shapes, materials, and age ranges. The right one can mean the difference between a baby who settles quickly and one who fights it every time. The wrong one, meanwhile, can rub against your baby's skin, fall apart faster than expected, or simply get rejected outright.
At MacroBaby, this is one of the questions our in-store specialists hear most from new parents, right alongside which stroller and which car seat to choose. Below is what actually matters when picking a pacifier, based on the three factors that make the biggest difference: age, material, and shape.
Age range comes first
Pacifiers are sized for a reason. A nipple made for a newborn is smaller and softer than one made for an 18 month old, and using the wrong size can affect latch and comfort. Most brands split their lines into three stages: 0 to 6 months, 6 to 18 months, and 18 months and up. If your baby arrived early or is on the smaller side, a newborn specific option like the Avent Soothie Snuggle tends to fit better than a standard 0 to 6 month pacifier.
Silicone or natural rubber
This is where most of the real decision making happens.
Silicone pacifiers are firmer, hold their shape longer, and are easy to sterilize. They're also what most hospitals hand out first, which is why the Avent Soothie is often the first pacifier a baby ever tries. If your baby took to that one in the hospital, staying in the same family, such as Philips Avent's Ultra Air or Ultra Soft lines, is usually the smoothest path forward.
Natural rubber pacifiers are softer and slightly more elastic, closer in feel to a nipple, which some babies who are also breastfed seem to prefer. BIBS is the brand most associated with this style, and its round, symmetrical nipple also means it works the same no matter which way it flips in your baby's mouth.
Neither material is medically better than the other. It comes down to what your baby will actually keep in their mouth.
Orthodontic and symmetrical shapes
You'll see the word orthodontic a lot on pacifier packaging. It describes a nipple shape that flattens slightly on one side to reduce pressure on the roof of the mouth and support natural jaw development. Chicco's PhysioForma line, including this PhysioForma one-piece pacifier, is built around this shape and is a common pediatrician recommendation for babies who use a pacifier most of the day.
Symmetrical designs, the round shape used by BIBS and the Avent Soothie, solve a different problem. They work no matter which way they land in the mouth, which matters more in the newborn stage before babies are in control of positioning.
Breathable shields matter more than people expect
Extended pacifier use, especially in warm weather or long stretches in a car seat or stroller, can lead to skin irritation where the shield touches the face. Philips Avent's Ultra Air line, such as this Ultra Air pacifier, uses a shield with large airholes built specifically to reduce that. It's a small detail that ends up mattering a lot for babies in hot climates like Florida.
Who each type fits best
- Newborns straight out of the hospital: stick with a Soothie-style one-piece silicone pacifier for the first few weeks
- Breastfed babies who reject silicone: try a natural rubber round pacifier like BIBS before assuming your baby does not like pacifiers
- Babies who use a pacifier all day, every day: an orthodontic shape like PhysioForma is worth the switch
- Babies with sensitive skin or in warm climates: prioritize a breathable shield design
- Parents who want extra protection on the go: pair any pacifier with a case or clip, such as a Primo Passi pacifier case, to keep it clean between uses

Keeping it clean and knowing when to replace it
Check the nipple regularly for cracks, stickiness, or discoloration, and replace the pacifier at the first sign of wear rather than waiting for it to fail completely. Most brands recommend replacing every one to two months even with normal use. Sterilize before first use and wash regularly with warm water and mild soap. Boiling or steam sterilizing works fine for silicone, but check your specific pacifier's care instructions before doing the same with natural rubber, since rubber breaks down faster under high heat.
Frequently Asked Questions
Is silicone or natural rubber safer for babies?
Both are considered safe when BPA-free and used within their recommended age range. The choice mostly comes down to what your baby accepts, not a safety difference between the two materials.
What does orthodontic mean on a pacifier?
It describes a nipple shape flattened on one side to reduce pressure on the developing palate and support healthier jaw alignment during frequent or prolonged use.
How often should I replace my baby's pacifier?
Every one to two months under normal use, or immediately if you notice cracks, tears, stickiness, or discoloration in the nipple.
Can I use the same pacifier my baby had in the hospital?
Yes. Hospitals typically use the Philips Avent Soothie, and continuing with that same pacifier or moving to another product in the same line is usually the easiest transition.
My baby refuses every pacifier we try. What should I do?
Try a different material first, silicone versus natural rubber, before switching shapes again. Texture and flexibility make a bigger difference to most babies than shape does.
Do pacifiers affect breastfeeding?
Most pediatric guidance suggests waiting until breastfeeding is well established, generally around three to four weeks, before introducing a pacifier, to avoid nipple confusion. Talk to your pediatrician about timing for your specific situation.
