Chicco Physio Air Lumi 4m+ pacifier, born from Chicco research, is the pacifier 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 groove. Thanks to the reduction in bulk, it allows the tongue to naturally position itself forward and upward inside the mouth. The shape of the nipple allows the force of the tongue's thrust on the palate to be correctly distributed even laterally, thus promoting its correct development. Palatine ridges. Small reliefs on the head of the nipple, 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 nipple promotes optimal mouth closure and is inclined at the top 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.
