Your options have never been better with Dr. Brown?s Natural Flow? Options+? Wide-Neck Bottle. From nipple to base, the Options+? Wide-Neck Bottle makes for a comfortable feeding experience for baby and eases the transition from breast to bottle and back again. Starting at the top, the NEW breast-like nipple shape is correctly contoured for a proper latch and a more natural bottle feeding experience – perfect for switching from breast to bottle and back again! Each nipple is specially engineered to offer the same consistent, natural flow, so you and baby know what to expect in every feeding. Together with the anti-colic internal vent system, they offer a reliable and trusted bottle feeding experience that makes Dr. Brown?s the #1 pediatrician recommended bottle in the U.S. But it doesn?t stop there. The anti-colic internal vent system features an enhanced design to improve an already innovative feeding experience: ? Clinically proven to reduce colic ? Decreases spit-up, burping, and gas ? Shown to better preserve nutrients in breast milk and formula ? Aids in digestion for a good night?s sleep ? Offers a flow rate that supports breastfeeding. It?s Good to Have Options+? Our bottles work best with the vent system in place ? but it?s great to have options when baby?s feeding develops. Just remove the vent when you feel it?s time ? no need to introduce a different bottle. See, the vent system isn?t the only means of venting in the Options+? bottle. Our bottle nipples feature their own venting system that offers a feeding experience similar to most nipple-vented bottles. Options+? is dishwasher (top rack) and sterilizer safe. BPA free. 0m+. Includes 1x 150 ml Wide-Neck bottle.
