A pack of 2 First Choice+ Baby Bottle Size 2 Latex Teats. These teats come with a medium size feed hole, which is suitable for breast milk and formula. These teats feature 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. It so true to nature that most babies hardly notice the difference. A mother's nipple adapts perfectly to a baby's mouth, that is why the new, NUK First Choice+ 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. Latex is popular with many parents because it is softer and more flexible which can make it easier for some babies to adapt to and it is also more bite-resistant. NUK First Choice+ teats are compatible with all First Choice and First Choice+ bottles. Approved by the Oral Health Foundation. For safety and hygiene purposes replace teat after 1-2 months use or sooner should signs of wear appear. Sterilise bottles and teats using steam, cold water sterilisation or a NUK Steam or Microwave Steriliser. Dishwasher sterilisation is not suitable as this can cause material damage. Please note: sterilise all parts for 5 minutes before first use and clean and sterilise thoroughly before each subsequent use. Age suitability: 6+ months.
