Dr. Brown's Milestones Sippy Bottle with Handles is the perfect first step from bottle to cup. Introducing a sippy spout has never been simpler - the soft silicone sippy spout is used in place of a nipple on the Dr. Brown's bottle that baby is already familiar with. Easy-grip 100% silicone handles are removable and fit most narrow bottles, while the snap-on cap keeps the spout clean when on the go. Sippy spout fits any Dr. Brown's Options+ Narrow bottle after vent is removed. All parts are sterilizer and dishwasher safe (top rack). 8 oz/250 ml, 6m+. BPA free.
