Our Anti Colic Bottles for Baby are designed for new parents & caregivers seeking a reliable and safe feeding option for their little ones. Our patented Duo-Flo Anti Colic natural flow Nipples minimize colic, gas, and spit-up by flexing and adjusting the milk flow according to your babys feeding pace, ensuring a smooth and uninterrupted feeding experience with no nipple collapse and less air in baby\'s tummy.

Each bottle includes a set of nipples that are interchangeable to accommodate your growing baby.

Designed with leak-proof and 4 easy to assemble pieces, our anti colic bottles are dishwasher safe on the top rack for convenience for new & busy parents. The standard neck bottles fit several standard breast pumps for easy and efficient breast milk storage.
