BIBS pacifiers come in different sizes because babies’ sucking patterns, mouths and preferences change as they grow. If you’re deciding between BIBS Size 1, Size 2 and Size 3, start with your baby’s age, the specific BIBS pacifier model and the manufacturer guidance for that product.
This guide explains how BIBS pacifier sizing works, why nipple shape matters too and what to consider before moving to another size. Because BIBS offers several pacifier families and nipple styles, always check the packaging or current product instructions for the exact pacifier you purchase.
BIBS Pacifier Sizes Explained
BIBS commonly offers Size 1, Size 2 and, on selected styles, Size 3. The sizes generally progress from smaller nipples for younger babies toward larger options for older babies and toddlers. The important catch is that age guidance can vary by pacifier family and nipple style, so there is not one age chart that should be treated as universal across every BIBS product.
BIBS Size 1
Size 1 is generally the smaller BIBS pacifier size and is commonly selected for newborns and younger infants. If you are introducing a pacifier early, check that the exact model’s manufacturer guidance is appropriate for your baby’s age.
BIBS Size 2
Size 2 has a larger nipple than Size 1 and is commonly used as babies grow. Moving from Size 1 to Size 2 should be based on the guidance for the specific BIBS pacifier plus your baby’s comfort and preference rather than a rigid birthday deadline.
BIBS Size 3
Size 3 is offered on selected BIBS pacifier styles for older babies or toddlers according to those products’ guidance. Not every BIBS collection is available in every size, so verify the options for the pacifier family you are considering.
BIBS Size 1 vs. Size 2
The key difference is nipple size: Size 1 is generally smaller, while Size 2 is larger. The shield, nipple shape and material can also vary between BIBS pacifier families, which means size is only one part of choosing a pacifier.
Pacifier Shape Matters Too
BIBS offers different nipple shapes, including round, symmetrical and anatomical designs. Babies can develop strong preferences for one shape or material, so switching nipple shape may sometimes make more sense than simply changing size.
If your baby rejects one BIBS pacifier, that does not necessarily mean every BIBS size or shape will feel the same. Compare the options available for your baby’s age and follow the instructions for the specific product.
How to Choose a BIBS Pacifier Size
Start with the age guidance for the exact pacifier model. Then consider whether your baby comfortably accepts the nipple shape and size. Inspect pacifiers frequently and replace them when they show wear, damage or deterioration, following BIBS care and replacement instructions.
A pacifier should always be used as designed. Do not modify the nipple or shield to change the fit, and do not continue using a damaged pacifier.

Frequently Asked Questions
What is the difference between BIBS Size 1 and Size 2?
Size 1 generally has a smaller nipple and Size 2 a larger nipple. Check the current age guidance for the exact BIBS pacifier family because recommendations can differ by model and nipple style.
When should I switch from BIBS Size 1 to Size 2?
Use the manufacturer’s guidance for your specific BIBS pacifier as your starting point rather than assuming every baby needs to switch at exactly the same age. Comfort, nipple shape and the particular pacifier model also matter.
Does BIBS make a Size 3 pacifier?
Yes, Size 3 is available in selected BIBS pacifier styles. Availability and age guidance depend on the specific pacifier family.
Are all BIBS pacifiers the same shape?
No. BIBS offers multiple nipple shapes and materials across its pacifier collections. Two pacifiers with the same size number can therefore offer a different feel.
How can I tell what size my BIBS pacifier is?
The safest reference is the original packaging and product information for your specific pacifier. If you cannot confidently identify an older pacifier’s size or condition, compare it with current manufacturer information before continuing to use it.
