Chicco Physio Air Pink Soother 4m+, from Chicco research, the soother was born that promotes the anatomical-functional development of the baby's palate and tongue, satisfying their natural sucking instinct. Soft shield made entirely of natural rubber, it is ideal for sleeping. Groove for the tongue. Thanks to the reduced bulk, it allows the tongue to naturally position forward and upward inside the mouth. The shape of the teat allows for correct distribution of the tongue's thrust force on the palate, even laterally, thus promoting its correct development. Palatine ridges. Small reliefs on the head of the teat, reference points for the correct positioning of the tip of the tongue for adequate upward thrust during sucking. Super thin profile. The neck of the teat promotes optimal mouth closure and is inclined at the top to accommodate the natural position of the tongue. Sold in a twin pack. Available in three different sizes: 0m+ 4m+ 12m+ to offer a soother proportionate to the growth of the baby's mouth.
