When it comes to pacifiers, no size or shape is right or wrong because every baby is different. Babies have different preferences, different sucking techniques, and different oral anatomy. That's why we offer a variety of pacifiers to meet all these different needs. It's important to try different shapes and sizes to find the one that works best for your baby. That's why Bibs launched the BIBS Try-it collection. In this collection, you'll find pacifiers in 4 different categories, with a selection of all our teat types (round, symmetrical, and anatomical) and materials (natural rubber latex and silicone). The 0-6 month collection includes: 1x Color (Size 1 - Natural Rubber Latex) 1x De Lux (Size 1 - Silicone) 1x Couture (Size 1 - Natural Rubber Latex) 1x Supreme (Size 1 - Silicone)
