Kick colic to the curb and make cleaning up a snap with Boon's Nursh and Mod feeding and cleaning bundle. Nursh bottles feature an air-free feeding design with a 100% platinum food-safe silicone pouch that collapses as your baby drinks, helping prevent colic symptoms (say goodbye to gas and spit up!). Other baby bottles use vents or valves that introduce air into milk to help it flow, but Boon Nursh bottles don't. Our bottles mimic breast feeding with no added air. Plus, no vents mean easy cleaning and assembling (because who needs a 2 am bottle puzzle?). Also not complicated? Nursh lids that fit perfectly onto our bottles for simple storage of breast milk in the fridge or freezer, and storage buns that make it easy to keep a clean pouch and nipple ready while on the go. When baby's ready to transition away from the bottle, the Nursh straw lid lets them keep holding the shape they've grown to love and is an easy way to transition them to a spill-proof straw sippy cup. And to clean it all up through every stage? It's the Mod bottle brush set to the rescue! With four brushes in different sizes, each with durable nylon bristles which are great for getting the goop out of Boon bottles, straws, sippy cups, and breast pump parts, Mod makes cleaning easier and looks great while doing it!
