The Physio Soft soother is anatomical and functional because it adapts to the anatomy of the mouth and correctly stimulates oral functions. Made of 100% natural rubber, it is very soft, convex and elastic and therefore does not leave pressure points. The heart-shaped air holes provide additional ventilation in the mouth, reducing salivary congestion and preventing irritation. The ultra-thin profile and anatomical shape help the child to close the mouth properly and to exert a correct pressure on the palate with the tongue. The small elevations on the tip of the teat are used by the child to guide the tongue. It also has a teething ring that massages the child's gums during the sensitive phase when the baby's milk teeth come (only for the product from 4 months).
