The NUK Nature Sense range has been designed with a teat that is closer to a mother's breast than ever before. The teat has 6 tiny openings for breast milk and water, mimicking the milk ducts that a mother actually has, ensuring a smooth and natural flow of feed for your baby. This way, your baby will enjoy a more natural feeding experience; almost as if feeding from mother's breast, making switching between breast and bottle so much easier. There is also a soft-zone which is gentle on the top of baby's delicate mouth, and the wide and flexible lip rest allows baby to latch on in a natural way. The anti-colic vent makes it possible to drink as if from the breast without a pause, which helps prevent your baby swallowing air and reduces the risk of colic. The extra-wide neck of these bottles mean they 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. Approved by the Oral Health Foundation. BPA Free. Before use and each subsequent use clean and sterilise bottles and teats, using cold water sterilisation or a NUK Steriliser. Dishwasher sterilisation is not suitable as this can cause material damage. For safety and hygiene purposes replace teat after 1-2 months use or sooner should signs of wear appear. 0% APR Representative: this product is eligible for Interest Free Credit, available when you spend £1000 or more on selected Nursery products.
