Dr. Brown’s Advantage Pacifier is designed with baby’s acceptance in mind. The Advantage Pacifier is a fully symmetrical soother, with a reversible bulb that can be placed in baby’s mouth in either direction. The 100% silicone bulb is soft yet sturdy with a round shape that satisfies baby’s suckling reflex. A unique open shield design reduces irritation by providing plenty of air for baby’s sensitive skin to breathe. Plus, the fun design is glow-in-the-dark making it easy to find in the dark for nighttime soothing. Advantage Pacifiers come in two stages as baby grows – 0-6m features a smaller bulb and shield for newborns. As baby grows, they can move up to the 6-18m stage, a slightly larger version of the same soothing design. Taste-free, odor-free, and BPA-free. Dishwasher (top rack) and sterilizer safe.
