• Clinically tested and proven for combined feeding. • NUK\'s Anti-Colic Air System reduces the risk of infant colic. • Modelled on the shape of a mother\'s nipple during breastfeeding, NUK Teats encourage latch on. • Approved by the British Dental Health Foundation for promoting healthy oral development. NUK First Choice+ Bottles are designed to be used with First Choice+ Teats. The First Choice+ Teat replicates a mother\'s nipple during breastfeeding and features the special, orthodontic, asymmetrical NUK shape, an extra wide lip support and new extra soft tip to fit baby\'s mouth perfectly, simulating breastfeeding as closely as possible - so true to nature that most babies hardly notice the difference.
