The Boon Nursh Reusable Replacement Pouch is designed for air-free feeding, allowing the silicone pouches to collapse as your baby drinks. This innovative design helps reduce the ingestion of air, minimizing gas, colic, and burps. Made from 100% food-safe silicone, these 8-ounce pouches are free from BPA and PVC, ensuring that milk never touches plastic during feeding. They are reusable, providing great value and reducing waste. Cleaning is easy as the pouches are dishwasher safe or can be flipped inside out for hand washing. Ideal for use with NURSH bottles, these pouches are perfect for parents looking for a convenient and safe feeding solution.
