Dr. Brown’s Level 3 Narrow Silicone Nipple is ideal for babies 6 months and older, offering a medium-fast flow that supports feeding at their own pace. Its patented Anti-Colic vent reduces colic by minimizing spit-up, burping, and gas, promoting a calmer feeding experience. Designed to closely mimic breastfeeding with a breast-like shape, it helps your baby latch naturally, easing transitions between breast and bottle. Made from soft, 100% silicone, this nipple fits all Dr. Brown’s narrow bottles and preserves milk nutrients for better digestion and sleep. Dishwasher and sterilizer safe, BPA free for your baby’s safety.
