Dr. Brown’s Medium Flow Level 2 Nipple is designed for growing babies who are ready for the next stage of bottle feeding. When used with Dr. Brown’s anti-colic bottle system, it helps support a more comfortable feeding experience by reducing colic, spit-up, burping, and gas. The vacuum-free design provides a steady and consistent flow, allowing babies to feed at their own natural pace. Its dependable flow rate helps maintain a comfortable feeding routine, while the soft, breast-like silicone shape encourages a proper latch and supports an easier transition between breastfeeding and bottle feeding.
