Made of 100% natural rubber, it is very soft, convex shaped and elastic and therefore leaves no pressure marks. The oral cavity is additionally ventilated via the heart-shaped air holes, 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 use the tongue to exert correct pressure on the palate. The small bumps on the tip of the teat serve the child as an orientation for the tongue. In addition, it has a teether that massages the child's gums during the sensitive phase when the milk teeth come (only for the product from 4 months).
