Your options have never been better with Dr. Brown 's Natural Flow Options+ Narrow Baby Bottle. From nipple to base, the Options+ Bottle makes for a comfortable feeding experience for baby. Starting at the top, each nipple is specially engineered to offer the same consistent, natural flow, so you and baby know what to expect in every feeding. The soft silicone nipple helps baby naturally latch while the anti-colic vent system lets baby feed without fuss. Together, they offer a reliable and trusted bottle feeding experience that makes Dr. Brown 's the #1 pediatrician recommended bottle in the U.S. 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. With the vent system removed, the feeding experience is similar to most nipple-vented bottles.
