Brand new lot of 3 bottles in box. Box is open. Decreases spit-up, burping and gas. Consistent Flow Vacuum-free feeding is closest to breastfeeding and Dr. Brown’s silicone nipples provide a consistent flow so babies can feed at their own pace. The breast-like nipple shape encourages a proper latch for a more natural bottle feeding experience and eases the transition from breast to bottle and back again. Dr. Brown’s Wide-Neck bottle is designed to nourish through all of baby’s feeding stages and is recyclable. Safe for use in dishwasher (top rack only), electric and microwave sterilizers or boiling water. BPA Free.
