The 300 ml NUK Anti-Colic Professional baby bottle made of lightweight, shatterproof polypropylene (BPA free) is the answer to baby's colic worries. Swallowing air while drinking is a major cause of typical colic symptoms such as bloating, abdominal cramps and constant screaming. However, the Professional Ventilation System of this baby bottle now prevents air swallowing even more effectively. In addition, the bottle has temperature control and shows at a glance when the correct drinking temperature has been reached. The original NUK teat is also modeled on the shape of the nipple when breastfeeding. It leaves enough space for your baby's tongue and jaw for the natural sucking movement. With its Soft zone, the tip of the silicone teat hugs your baby's palate even better – for a natural feeling when drinking. Due to its particularly natural shape, the NUK teat is very well accepted by infants. This makes it also suitable for babies who combine breastfeeding and bottle feeding. The baby bottle can be combined with all NUK First Choice products.
