Dr. Brown’s uniquely designed Wide-Neck Level 4 Nipple is a fast-flow nipple that works together with our patented internal vent system to help growing babies feed at their own pace. Each Level 4 Nipple offers the same consistent flow, so both you and baby know exactly what to expect. Made of super-soft, high-grade silicone, the Level 4 Nipple fits both Dr. Brown’s Natural Flow Wide-Neck Bottles and Dr. Brown’s Options Wide-Neck Bottles. The suggested age range for the Level 4 nipple is 9 months+ but baby’s preferred flow rate may vary. Easily clean this dishwasher (top rack) and sterilizer safe nipple. BPA free.
