• Supports breastfeeding. • It is BPA free. • Improved NUK anti-colic air system. A mother\'s nipple adapts ideally to a baby\'s mouth, that is why the new, improved NUK First Choice Plus teats replicate a mother\'s nipple whilst breastfeeding. The feeling is not only pleasant for babies, the soft nipple easily takes on different shapes whilst also promoting the development of the mouth, lips and tongue. The NUK First Choice Plus teat features the special, orthodontic, asymmetrical NUK shape, an extra wide lip support and new extra soft tip to fit baby\'s mouth ideally, simulating breastfeeding as closely as possible. The NUK Teat also features the NUK anti-colic air system, which allows air to flow into the bottle through the improved vent, stopping baby swallowing air and helping to prevent colic.
