Chicco Physio Air blue soother 4m+, from Chicco research, the soother was born that promotes the anatomical-functional development of the palate and tongue of the child, satisfying his natural sucking instinct. Soft shield made entirely of rubber, it is ideal for sleeping. Tongue cavity. Thanks to the reduction of bulk, it allows the tongue a natural forward and upward positioning inside the mouth. The shape of the teat allows the force of the tongue's thrust on the palate to be correctly distributed even laterally, thus favoring its correct development. Palatine wrinkles. Small reliefs on the head of the teat, reference points for the correct positioning of the tip of the tongue for an adequate upward thrust during sucking. Super thin profile. The neck of the teat promotes optimal mouth closure and is inclined in the upper part to accommodate the natural position of the tongue. Sold in a double pack. Available in three different sizes: 0m+ 4m+ 12m+ to offer a soother proportionate to the growth of the baby's mouth.
