• 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 Oral Health Foundation for promoting healthy oral development. NUK First Choice+ Teats replicate the shape of a mother\'s nipple during breastfeeding. The extra soft tip easily takes on different shapes whilst also promoting the development of the mouth, lips and tongue. The orthodontic NUK shape, combined with the NUK First Choice+ extra wide lip support, makes it easier to alternate between breast and bottle feeding. The improved Anti Colic Air System minimises infant colic caused by the harmful swallowing of air. NUK First Choice+ bottles are fitted with a medium feed hole teat which is suitable for breast milk and formula. Silicone is a stronger and more durable material, which will last longer than latex. NUK Teats and Soothers are approved by the Oral Health Foundation. Additional details: Packaging size: 240mm x 130mm x 65mm Recommended age: 0-6m
