Very good pacifier, our baby will only accept it. The piece of rubber (silicone or ??) is convenient for take without risk of touching the nipple. Easy to clean since fully rubber or silicone ??? We're not sure but as it says BPA, this assumes rubber as there are no office in the silicone if I did not say anything stupid. A check nevertheless before buying if your baby does not support a particular subject. Too bad it will sell in the US, the time is very long ...
