Chicco Physio Air Lumi 4m+ pacifier, born from Chicco research, is the soother that promotes the anatomical-functional development of the baby's palate and tongue, satisfying their natural sucking instinct. Soft shield made entirely of silicone, it is ideal for sleeping. Tongue hollow. Thanks to the reduction of bulk, it allows the tongue to naturally position forward and upward within the mouth. The shape of the teat allows the tongue's thrust force to be correctly distributed 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 an adequate upward thrust during sucking. Super thin profile. The neck of the teat promotes optimal mouth closure and in the upper part is inclined to accommodate the natural position of the tongue. Sold in a double pack. Available in three different sizes: 0m+ 4m+ 12m+ to offer a pacifier proportionate to the growth of the baby's mouth.
