Nuk first choice+ rubber nipple, for a natural breastfeeding sensation, with the Nuk orthodontic shape. \ \ Nuk first choice has been the first choice of consumers for years in bottles designed based on breastfeeding. With the Nuk first choice+ nipple, we were able to come even closer to the natural way of feeding, with the aim of healthy development of the child's jaw and simulating as much as possible the feeling of breastfeeding from the mother's breast. \ \ natural shape, adapted to the jaw \ \ the special shape of the Nuk nipple is based on the shape that the mother's nipple takes when the baby breastfeeds. It provides the necessary space for your baby's tongue and jaw, so that natural breastfeeding movements can be made with ease. \ \ soft as a mother's breast \ \ with the new soft zone, the rubber nipple adapts to the palate even better – for a natural breastfeeding sensation \ \ prevents colic \ \ the improved anti-colic air system allows the natural flow of food, so that your baby drinks comfortably and relaxed, without swallowing air. \ \ clinically proven \ \ its particularly natural shape makes the nuk nipple particularly popular with breastfed babies. For this reason, it is ideal for babies who combine bottle feeding with breastfeeding.* \ \ * pediatric study moral et al. bmc pediatrics 2010, 10:6. \
