Made of 100% natural rubber, it is very soft, convex and elastic and therefore leaves no pressure marks. Through the heart-shaped air holes, the mouth area is additionally ventilated, so that saliva congestion is reduced and irritations are prevented. 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).
