Learning to drink independently is an important step in baby's development. The NUK Evolution Soft Spout Learner helps ease the transition from bottle to cup. The cup features easy to hold built-in ergonomic handles that are designed with little hands in mind. The soft spout is familiar to baby and gentle on gums. To keep your baby mess free, the cup is 100% spill and leak proof guaranteed. The Evolution Cup base can be used with all three lid types so you can easily transition between Learner, 360 and Straw as your baby grows.
