Made from 100% natural rubber, it is very soft, convex-shaped, and elastic, ensuring that it leaves no pressure marks. The heart-shaped air holes provide additional ventilation for the mouth, reducing saliva buildup and preventing irritation. The ultra-thin profile and anatomical shape help the child close their mouth properly and apply correct pressure distribution on the palate with their tongue. The small bumps on the tip of the pacifier serve as a guide for the child's tongue. Additionally, it features a teething ring that massages the child's gums during the sensitive phase when the baby teeth are coming in.
