Wide Breast-like Design Supports Breastfeeding
Milk Flows Smoothly with No Air Bubbles and No Leaking
Fits Any Regular Mouth Mason Jars
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 built-in FussFreeTM Ventilation System, meaning no extra tubes, bags or pieces to clean or keep track of.
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.
Made with Baby in Mind
Being made in the USA ensures with 100% certainty that our factory is using the safest, best quality materials and we know that our products are being made in a clean environment that meets the highest safety standards around.
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.
