The Born Free Glass Bottle features patented ActiveFlow Venting Technology that reduces air pressure and vacuum buildup, resulting in reduced gas and colic symptoms. The leak-free vent allows your baby to control the flow of milk, and helps to prevent nipple confusion. Because Born Free provides an experience closer to breastfeeding, your baby can easily switch between breast and bottle-feeding, allowing you to breastfeed longer. The easy-to-use bottles are top rack dishwasher safe, and naturally free from BPA and PVC. The flexible infant baby banana brush is the ideal infant training toothbrush that was invented by a mom-hygienist. The fun banana shape and soft texture are the perfect introduction and make brushing a fun experience as early as 3-4 months. It is made of the highest quality silicone and is compliant with the highest government standards.
