Many pacifiers have disadvantages that we have solved with the NucklyNatureSense: Cherry-shaped pacifiers can lead to dental misalignments, difficulty in nasal breathing, and redness. Asymmetrical pacifiers increase the risk of sucking confusion, promote unnatural tongue positions, and are often difficult to use correctly. The NucklyNatureSense, on the other hand, is breast-like, ergonomic, and fits perfectly to support your baby's natural development – without compromises.
