Dr. Brown’s 9 Oz/270 Ml Glass Wide-Neck “Options+” Bottle, 1-Pack

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.
