Top Benefits
Breast-like Shape and Flow
The wide design helps ensure a breast-like latch. Our nipples are designed to flow smoothly and smoothly to mimic the pace of breastfeeding.
Lactation Consultants recommend always using the slowest flowing nipple your baby will accept to promote a smooth transition from breast to bottle and back.

Built-in FussFreeTM Ventilation System
All of our nipples are designed with our FussFreeTM Ventilation System. This dual valve system allows air to be taken in and milk to flow smoothly out with no air bubbles to help prevent gas and colic.
Bonus: Our system is flawlessly built into the top of the nipples, so no special tubes, collars, bags or extra pieces needed!

Leak-Proof Guarantee
When turned upside down, a couple drops will come out. This is normal for all baby bottle nipples. Use those couple drops to test that the milk is not too hot.
But once the feeding begins and baby has latched, there should be no leaking—all our nipples and bottles come with a leak-proof guarantee.
