Pacifier Sizes & Materials: A Parent's Guide
Pacifiers (also called soothers or dummies) can be a lifesaver for soothing fussy babies and helping them self-settle. But with so many sizes, materials, and shapes available, choosing the right one can feel overwhelming. Should you choose silicone or latex? What size does your baby need? How do you keep them clean and safe?
In this guide, we'll walk you through everything you need to know about pacifier sizes and materials, from newborn to toddler. Whether you're preparing for a new arrival or looking to upgrade your current pacifier, understanding the options will help you make the best choice for your baby's comfort and safety.
Soothing vs Dental Considerations
Pacifiers serve an important soothing function—they satisfy babies' natural sucking reflex and help them self-settle. When used according to safe-sleep guidelines, pacifier use has been associated with lower SIDS risk. Always follow current safe-sleep guidance from health authorities.
However, prolonged pacifier use (especially beyond 2–3 years) can affect dental development and speech.
General guidance:
- Pacifiers are generally safe for newborns and infants when used appropriately
- Many manufacturers offer orthodontic or symmetrical designs; proper size and correct use are important. If you have concerns about oral development, consult your pediatric dentist
- Aim to wean off pacifiers by 2–3 years to minimize dental impact
- Never dip pacifiers in sugar or honey (choking and tooth decay risk)
- Replace pacifiers every 4–6 weeks or when damaged
Note: If you have concerns about your baby's oral development or pacifier use, consult your pediatrician or pediatric dentist.
Pacifier Sizes by Age
Pacifiers are sized by age to match your baby's mouth development. Using the correct size ensures comfort, safety, and proper oral development. Age ranges are manufacturer guidelines; always check the product's specific size/age chart.
Newborn / Size 0 (0–3 months)
- Teat size: Extra small, designed for tiny mouths
- Shield: Lightweight, small shield to avoid pressure on nose
- Features: Soft, flexible teat; easy for newborns to hold in mouth
- Note: Some brands (like BIBS) start at 0–6 months
Size 1 (0–6 months)
- Teat size: Small, suitable for most newborns and young babies
- Shield: Curved to fit baby's face, ventilation holes to prevent skin irritation
- Features: Orthodontic or round teat shape
- Popular choice: BIBS Colour Latex Soothers 0-6 months
Size 2 (6–18 months)
- Teat size: Medium, for growing babies and toddlers
- Shield: Larger shield with better ventilation
- Features: Firmer teat to withstand emerging teeth
- Transition tip: Move to Size 2 around 6 months or when baby's first teeth appear
- Popular choice: BIBS Colour Latex Soothers 6+ months
Size 3 (18+ months)
- Teat size: Large, for toddlers
- Shield: Extra-large shield for older children
- Features: Durable teat for active chewers
- Weaning note: Many experts recommend weaning off pacifiers by 2–3 years
Shield & Ventilation Notes
All pacifiers should have:
- Ventilation holes: Prevent skin irritation and allow airflow
- Curved shield: Fits baby's face comfortably without pressing on nose
- Minimum size: Shield must be larger than baby's mouth to prevent choking
- Handle or ring: Easy to remove; some babies prefer flat button-style
Pacifier Materials: Silicone vs Latex
The two main pacifier materials are silicone and latex. Both are safe when BPA-free, but they have different characteristics.
Silicone Pacifiers
Pros:
- Durable: Lasts longer than latex; doesn't degrade as quickly
- Odourless & tasteless: No rubber smell or taste
- Heat-resistant: Can withstand boiling and steam sterilization
- Hypoallergenic: No latex allergy risk
- Easy to clean: Dishwasher-safe (top rack)
Cons:
- Firmer texture: Some babies prefer the softer feel of latex
- Can tear: Once damaged, silicone can tear suddenly (check regularly)
Best for: Babies with latex allergies, parents prioritizing durability and easy cleaning
Latex Pacifiers
Pros:
- Soft & flexible: Natural rubber feels more like skin; many babies prefer it
- Warm texture: Feels warmer in baby's mouth than silicone
- Natural material: Made from rubber tree sap (renewable resource)
- Popular brands: BIBS is known for premium natural rubber latex pacifiers
Cons:
- Shorter lifespan: Degrades faster than silicone (replace every 4–6 weeks)
- Rubber smell: Natural latex has a mild rubber odour (fades with use)
- Latex allergy risk: Rare, but some babies are allergic to latex
- Heat sensitivity: Latex can wear faster from heat and detergent; follow manufacturer limits
Best for: Babies who prefer soft, flexible teats; parents prioritizing natural materials
BPA-Free & Safety Standards
All modern pacifiers sold in the UK/EU must be BPA-free and meet strict safety standards (EN 1400). Look for:
- BPA-free certification
- Phthalate-free materials
- Current EN 1400 safety compliance and secure part design (one-piece or firmly attached construction)
- CE marking (European safety compliance)
Cleaning & Sterilizing
Before first use: Sterilize by boiling for 5 minutes or using a steam sterilizer
Daily cleaning:
- Silicone: Dishwasher-safe (top rack) or hand wash with warm soapy water
- Latex: Hand wash with warm soapy water; latex can wear faster from heat and detergent—follow manufacturer limits
- Rinse thoroughly and air dry
Regular sterilization: For babies under 6 months, regular sterilization is recommended; follow brand instructions (boiling/steam). Frequency depends on your baby's age and environment.
Replacement schedule:
- Silicone: Every 6–8 weeks or when damaged
- Latex: Every 4–6 weeks or when sticky/discoloured
- Replace immediately if torn, cracked, or sticky
Use Cases & Safety Tips
For Sleep
- When used according to safe-sleep guidelines, pacifier use has been associated with lower SIDS risk. Always follow current safe-sleep guidance
- Offer pacifier at nap time and bedtime (don't force if baby refuses)
- If pacifier falls out during sleep, don't reinsert it
- Choose a glow-in-the-dark or night-time pacifier for easy finding
For Travel
- Pack 2–3 spare pacifiers in a clean soother box
- Use a pacifier clip to prevent loss (never attach to cot or around neck during sleep)
- Bring portable sterilizing wipes or a microwave sterilizer bag
Pacifier Clip & Holder Safety
- Use clips only when baby is awake and supervised
- Never use clips during sleep (strangulation risk)
- Choose clips that comply with EN 12586 safety limits (typically ≤22cm); always follow manufacturer warnings
- Choose clips with breakaway clasps for safety
- Attach to clothing, not around neck
Dishwasher-Safe Options
Silicone pacifiers are dishwasher-safe (top rack only). Latex pacifiers should be hand-washed to preserve the material. Always check manufacturer guidelines.

Frequently Asked Questions
How many pacifiers do I need?
Most parents find that 4–6 pacifiers is a good starting number. Here's why:
- 2 in rotation: One in use, one clean and ready
- 1–2 spares: For nappy bag, car, grandparents' house
- 1–2 backups: Pacifiers get lost frequently (especially when out and about)
Tip: Buy pacifiers in packs of 2 (like BIBS 2-packs) for better value. Keep spares in a clean soother box to maintain hygiene.
When should I size up to the next pacifier size?
Move to the next size when:
- Age milestone: Around 6 months (Size 1 to Size 2) and 18 months (Size 2 to Size 3)—these are manufacturer guidelines; check your product's specific size/age chart
- Teat looks small: If the teat looks too small for baby's mouth or they're chewing through it quickly
- Baby rejects it: Some babies naturally outgrow their current size and refuse it
- Teeth appear: Firmer Size 2 teats withstand teething better than Size 1
Important: Don't rush to size up. Babies can comfortably use Size 1 (0–6 months) until 9–12 months if it still fits well. The age ranges are guidelines, not strict rules. Always check the pacifier for damage—teething babies can wear through teats faster.
What about latex allergy concerns?
Latex allergies in babies are rare but possible. Signs of a latex allergy include:
- Rash or hives around the mouth
- Swelling of lips or tongue
- Difficulty breathing—if lip/tongue swelling or breathing difficulty occurs, call emergency services immediately
- Persistent fussiness or refusal of pacifier
If you suspect a latex allergy:
- Stop using latex pacifiers immediately
- Switch to silicone pacifiers (hypoallergenic)
- Consult your pediatrician for allergy testing
- Check for latex in other baby products (bottle teats, toys)
Prevention: If there's a family history of latex allergies, start with silicone pacifiers. However, most babies tolerate natural rubber latex without issues, and many prefer its soft, warm texture.
Ready to Choose Your Pacifier?
Choosing the right pacifier size and material comes down to your baby's age, preferences, and any allergy considerations. Whether you choose soft, natural latex pacifiers from BIBS or durable silicone options, prioritize BPA-free materials and proper cleaning practices.
Remember: every baby is different. Some take to pacifiers immediately, others never do—and both are perfectly normal. If your baby refuses a pacifier, don't force it. Try different shapes and materials, but ultimately follow your baby's lead.
