Physiological and anti-colic pacifiers in size U XS extra slow flow: 0 - 4 months Slow flow S: 0 - 6 months Average flow M: 0 - 24 months Fast flow L: 6 - 24 months The Élhea physiological and anti-colic pacifier, made of extra-soft silicone, was developed to offer sensations similar to breastfeeding. It adapts ideally to the shape of the baby's palate and contributes to good oral development. Its anti-colic system reduces air absorption and facilitates the digestion of toddlers. Small precision: The flows of the pacifiers are indicated under the base of the pacifier (S = slow flow, M = medium flow, L = dense flow). The numbers on the bottom of the pacifier correspond to those in the manufacturing series. Designed to adapt as closely as possible to their needs, the Slow flow (S) pacifier is ideal for breast-fed or premature babies, in particular to avoid the risk of breast-pacifier confusion.
