Durable and Heat Resistant: The bottle base is made from polyphenylsulfone (PPSU), a medical-grade plastic known for its durability and heat resistance. This material won't retain odors or stains left behind by breast milk or formula, ensuring hygiene and longevity. Super Soft Silicone Teat: The bottle teat is made from super soft, resilient silicone with a matte texture that feels closer to skin, ensuring complete comfort during feeding time. Breast-Like Teat Design: Developed with input from breastfeeding experts, the teat features a flexible, easy latch-on design with a patented ripple pattern. This design mimics the natural flex, stretch, and movement of a mother's breast, promoting a natural latch and feeding experience for the baby. Anti-Colic Features: The bottle is equipped with an Easi-Vent valve in the teat, which reduces excessive air flow during feeding. This helps babies ingest more milk and less air, thereby reducing the risk of colic symptoms. Wide Bottle Neck: The wide bottle neck simplifies the cleaning process and encourages intuitive feeding actions in babies. The compact bottle shape also allows the baby to be closer to the parent during feeding sessions. Easy to Clean and Sterilize: The wide neck design makes cleaning the bottle easy, and it is suitable for use in the dishwasher, microwave, and steam sterilizers. The bottle can be easily disassembled into three parts for thorough cleaning and sterilization. Overall, the Tommee Tippee Closer to Nature PPSU Baby Bottle offers durability, comfort, and convenience for both parents and babies during feeding time. (description exceeds maximum possible length)
