With the NUK Nature Sense Starter Set you have everything you need to get started as the pack contains two NUK Nature Sense Baby Bottles with NUK Nature Sense Teats which are closer to a mother’s breast than ever before but also one of our popular NUK Genius Silicone Soothers, “My First NUK”, which for convenience and hygiene comes with a NUK Soother Cover.The NUK Nature Sense Baby Bottle and teat has been developed with a sense of nature. Similar to a mother’s nipple, the teat has several tiny openings which are modelled on the milk ducts in a mother’s breast and make the NUK Nature Sense a bottle with which babies can enjoy a familiar feeling when drinking and, above all else, a natural flow. The soft zone is gentle on the top of baby’s delicate mouth, the wide lip rest lets your baby latch in a natural way and the innovative anti-colic vent helps prevent your baby from swallowing air and reduces the risk of colic.The bottle is made of high-quality plastic (PP), is BPA-free and hard-wearing. The extra-wide bottle neck means it can be filled and cleaned in no time at all and the protective cap closes all the tiny openings to prevent leakage when mixing formula or when out and about.The NUK genius soother is based on the approved orthodontic NUK shape with an even softer, more flexible baglet which reduces the pressure on baby's jaw and teeth, reducing the risk of teeth misalignment whilst the NUK Air System helps to ensure that the mouthpiece remains soft and flexible. Genius soothers are made from soft-flex silicone, which is extremely flexible yet bite resistant.
