Maximum ventilation for your baby's skin. Thanks to its large ventilation holes, it allows the skin to breathe, preventing saliva stagnation. Thanks to its special shape, the Chicco Physio Forma Air supports the correct development of the mouth and helps to position the tongue forward, aiding physiological breathing. • ERGONOMIC SHAPE : It adapts perfectly to the baby's mouth, allowing natural lip movements during sucking. • ROUNDED AND SMOOTH EDGES: They rest gently on baby's sensitive skin. • VENTILATION HOLES: They ensure maximum air circulation. They prevent the accumulation of saliva and prevent irritation. • ACTIVE SILICONE TEAT: Silicone is a transparent and hygienic material, tasteless and odorless, and does not deform over time. • Available in 3 different sizes: 0-6m, 6-16m and 16-36m, to ensure the correct pacifier size for each stage of growth.
