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, leaving no pressure marks. The heart-shaped air holes additionally ventilate the mouth, reducing saliva congestion and preventing irritation. The ultra-thin profile and anatomical shape help the child to close the mouth correctly and apply correct pressure to the palate with the tongue. The small elevations at the teat tip serve as orientation for the child's tongue. In addition, it has a teething ring that massages the child's gums during the sensitive phase in which the milk teeth come (only with the product from 4 months).
