- Respects the Babys Oral Development. The Physiological nipple is designed to avoid intruding into the oral cavity and provide the baby with the same sensation they experience in their natural/physiological state without a pacifier. - The nipple has a thinner and wider neck, a shorter and flatter head that allows the mouth to close almost completely. - Symmetrically, it doesnt matter which side the pacifier is placed on and it doesnt matter if the baby turns it over, it always stays in the right place. - Thin, ultra-soft silicone with a sandblasted finish that mimics the texture and shape of the mothers nipple for maximum warmth and super-flexible movement that adapts the nipple to the palatal cavity. PRECAUTIONS AND WARNINGS - Do not attach ribbons, strings or chains to the pacifier other than those intended for that purpose due to the risk of suffocation. - Carefully and periodically inspect the pacifier for possible damage, especially when the child has teeth. Pull the pacifier in all directions and discard it at the first sign of deterioration or fragility. - Do not expose the pacifier to direct sunlight or a heat source, or to contact with a disinfectant for longer than recommended by the manufacturer, as this could damage the nipple. - Do not place the teat in sweet substances or medications.
