Dr. Brown’s Options+ Narrow Preemie Baby Bottles are designed specifically for premature babies or those experiencing feeding difficulties. These 2 oz/60 mL bottles feature Preemie Flow Nipples, which offer the slowest flow rate to ensure a controlled feeding pace. The anti-colic internal vent system helps reduce colic, spit-up, burping, and gas, while preserving bottle milk nutrients. Made from high-grade silicone and polypropylene, these bottles are BPA-free and dishwasher safe. The breast-like shape encourages a proper latch, making the transition from breast to bottle and back easier. This package includes four 2 oz/60 mL bottles with Preemie Flow Nipples.
