Dr. Brown's Options+ Narrow Bottle to Sippy Baby Bottle Start Kit, Blue, 8oz, 1-Pack, Blue Rainbow

Transition from bottle to cup with Dr. Brown?s Natural Flow? Anti-Colic Options+? Sippy Bottle Starter Kit. Introducing a sippy spout has never been simpler with the nipple to sippy conversion kit. The soft 100% silicone sippy spout is used in place of the nipple on the Dr. Brown?s bottle that?s already familiar to baby, while the snap-on cap keeps the spout clean when on-the-go. The sippy spout fits any Dr. Brown?s? Options+? Narrow bottle after the internal vent is removed. All parts are safe for use in dishwasher (top rack only), electric and microwave sterilizers or boiling water. 6m+. BPA free.
