Dr. Brown’s Natural Flow Level 2 Wide-Neck Baby Bottle Silicone is designed for babies aged 3 months and above. The medium flow nipple, made from 100% silicone, is part of an anti-colic system that reduces colic, spit-up, burping, and gas, providing a comfortable feeding experience. The vacuum-free feeding mimics breastfeeding, allowing babies to feed at their own pace. The breast-like nipple shape encourages a proper latch, easing the transition from breast to bottle and back. The product is dishwasher safe and fits all Dr. Brown’s Options+ wide-neck bottles.
