The new Nuk Perfect Match nipple is incredibly soft and flexible, so it fits gently on your baby's lips and palate. The shape of the nipple makes it easy for your baby to latch on the nipple in the way recommended by midwives and pediatricians: with the mouth fully open and the lips surrounding the nipple, in the most natural way. This means that the milk flows smoothly, so your baby can drink comfortably. Wide lip area: The wide lip area feels like skin as your baby drinks. Their mouth never comes into contact with the hard plastic parts of the bottle. Nuk Anti-Colic air escape valve : The Nuk Anti-Colic air escape valve against colic and the choice between three different nipples ensure a smooth flow. Temperature at a glance: The patented Nuk Temperature Control indicator changes color from blue to white when the contents are too hot. It's great to know that you're always feeding your baby at the right temperature. Important: However, check the temperature again before feeding. Leak protection: With its lid, the bottle is protected from leaks and the nipple does not get dirty. Easy to clean: The bottle consists of only four parts that are easy to clean. Convenient shape: With a shape that tapers downwards, the bottle is easy to grip when feeding. Even when you're half asleep. Nuk bottles meet the European safety standard EN14350. It can be combined with all NUK Perfect Match accessories and all NUK Soft & Easy breast pump accessories .
