Dr. Brown's Natural Flow Level 4, Wide-Neck Baby Bottle Nipple, Fast Flow, 9m+, 100% Silicone, 6 Pack

The uniquely designed Dr. Brown’s Natural Flow® Options+™ Wide-Neck Level 4 Nipple is a fast flow nipple, designed for babies who are more developed or prefer a quick flow. The breast-like shape encourages a proper latch for a more natural bottle feeding experience. Designed alongside medical professionals, the correctly contoured nipple shape and high-grade, soft silicone offer a more comfortable feeding experience and help to avoid nipple confusion. Perfect for switching from breast to bottle and back again! Together with the anti-colic internal vent system, the Level 4 Wide-Neck Nipple gives baby vacuum-free feeding that is clinically proven to reduce colic, decreases spit-up, burping, and gas, better preserves nutrients, and aids in digestion for a good night’s sleep. The suggested age range for the Level 4 nipple is 9 months+ but baby’s preferred flow rate may vary. Fits Dr. Brown’s® Options+™ Wide-Neck bottles. Dishwasher (top rack) and sterilizer safe. BPA free.
