The pacifier is always well-positioned thanks to its symmetrical nipple This new generation of pacifiers features an even thinner and more flexible symmetrical nipple made from silicone and latex, always well-positioned in the baby's palate. Our test moms loved: The thinness and flexibility of the nipple that allows for good palate development and helps reduce the risk of jaw deformation The reversible nipple that allows the baby to put the pacifier back in the correct position by themselves The translucent, colorful, and ventilated reversible shield The thin and modern ring that is easy to grab The three sizes, 0-6 months, 6-18 months, and 18-36 months, adapted to the baby's oral cavity The air holes that facilitate air circulation, preventing the shield from irritating the mouth The design that works both ways and the vibrant colors
