Bibs Colour pacifier is the original BIBS pacifier and has been on the market for over 40 years. It has the signature round BIBS shield with three vent holes and round BIBS engraved handle ring. The nipple is round and resembles the shape and size of the mother's breast to provide comfort to your baby. Features Recommended by midwives to support natural breastfeeding. The shield is made of 100% food-safe material. Completely free from BPA, PVC, and phthalates. Designed and manufactured in Denmark/EU. Nipple Information The round nipple promotes a similar tongue placement and sucking technique when breastfeeding, since the round shape allows the sides of the tongue to elevate and cup around the nipple, just like it does during breastfeeding. The nipple is equipped with a valve, letting out air when the baby closes down on the nipple. This ventilation system causes the air from inside the nipple to be pushed out through the valve thereby flattening the nipple to shape naturally after the baby's oral cavity. The valve is also the reason why water can be presented inside the nipple after cleaning and sterilization. If this is the case, simply just squeeze the nipple flat to press out the excess water.
