Innovation. Suck on that! It’s the best thing to happen to feeding since nipples. The revolutionary air-free feeding design of our Nursh Silicone Pouch Bottle features a 100% silicone pouch that collapses as your little one drinks, squeezing out the nasty gas-inducing air that causes colic. No straws, vents or valves here—so it’s a snap to clean and assemble. The silicone can even be boiled, sterilized, and frozen, making it a truly versatile baby bottle option. Each of the silicone bottles in this set are also dishwasher safe for quick and easy cleaning that makes taking care of them a snap. These 4-oz infant bottles include stage 1 slow flow nipples that are perfect for newborns learning to feed. These slow flow nipples are also designed to mimic mom to ensure your baby stays comfortable and at ease as they begin to feed from their new silicone baby bottles. Boon's Nursh collection is perfect for new moms. Explore more of the collection to discover storage lids, buns, additional pouches, and more!
