NUK First Choice+ Teats are clinically proven for combined feeding*. The award winning NUK First Choice+ Teat features the NUK orthodontic shape, a super soft zone which adapts perfectly to baby's palate and an extra wide lip support. The teat mimics the shape of a mother¿s nipple during breastfeeding which encourages latch on and is designed to make it easier to switch between breast and bottle-feeding. The NUK Anti-Colic Air System reduces the risk of infant colic caused by a harmful swallowing of air. The NUK First Choice+ 0-6mths Latex Teat is softer and more flexible than silicone which makes it easier for some babies to adapt to. It features a Medium size feed hole which is suitable for milk and formula. Small and Large feed hole teats are also available in either Silicone or Latex. BPA Free *Moral et al.
