Get the Dr. Brown's Advantage - the soother designed with baby's acceptance in mind! The Advantage Soother is a fully symmetrical soother, with reversible bulb that fits in baby's mouth either right-side up or upside down. The 100% silicone bulb is soft but sturdy, using a rounded shape that satisfies baby's suckling reflex. A unique shield design reduces irritation by providing plenty of air for baby's sensitive skin to breathe. Advantage Soothers grow with baby, coming in two stages to fit developing faces. Taste-free, odour-free, and BPA-free. Quickly clean in the dishwasher (top rack) or sterilize by boiling, microwave, or electric sterilizer.
