Orthodontic Shape: The teats have an orthodontic shape with a super soft zone that mimics the shape of a mother's nipple during breastfeeding. This design makes it easier for the baby to accept the teat and for mothers to alternate between breast and bottle-feeding. Adaptable Shape: The natural shape of the NUK teat adapts to the baby's sensitive palate, providing comfort and support while helping to exercise their jaw and teeth. Anti-Colic Air System: The NUK Anti-Colic Air System minimizes infant colic caused by the harmful swallowing of air, promoting a more comfortable feeding experience for the baby. Flow Control Y-Cut: The teat features a Flow Control Y-cut, allowing the baby to regulate their drinking intuitively. This feature is suitable for all types of liquids and helps prevent overfeeding. Transition to Independent Drinking: The teats help facilitate the transition to independent drinking, supporting the baby's development as they grow. Wide Lip Support: The extra wide lip support simulates breastfeeding as closely as possible, making it suitable for combination feeding. Compatibility: The teats fit all NUK First Choice+ bottles, providing versatility and convenience for parents. BPA-Free: The teats are BPA-free, ensuring they are safe for the baby to use. Made in Germany: They are made in Germany, adhering to high-quality standards. Overall, the NUK First Choice+ 6-18 Months Flow Control Teat 2 Pack offers a comprehensive solution for feeding babies, supporting their development and providing comfort and convenience for parents.
