The Boon Nursh Reusable Silicone Baby Bottle Bundle includes 3 slow flow 4oz bottles and 3 extra slow nipples, providing a complete feeding solution for your newborn. The revolutionary Nursh bottles feature 100% silicone collapsible pouches that squeeze out air as baby drinks, reducing gas and colic. With no straws, vents or valves, these pouches are simple to assemble and easy to clean by boiling, sterilizing or freezing. The dishwasher-safe bottles ensure quick cleanup between feedings. Complementing the Nursh bottles are Boon's 100% silicone slow flow nipples, specially designed to feel natural for easy latching and proper tongue positioning. Their squishy silicone material contains no BPA, PVC or other toxins. These nipples deliver an ultra-slow flow that's suitable for newborns, working with the Nursh bottles to provide a complete air-free feeding system. With fewer parts than traditional bottles, the Boon system makes feeding time simpler for both parents and babies.
