The NUK Learner Cup easily promotes baby’s transition from breast or bottle to sippy cup. This Learner Cup features a spill-proof soft spout that is gentle on teeth and gums, and it includes an air vent that helps reduce swallowed air. The cup also comes with easy-to-grip, removable handles that your growing child will love. NUK Learner Cups are BPA-free and dishwasher-safe. Our 10 oz Learner cups are recommended for ages 9m+ and this one features your little one's favorite Disney Princesses: Belle, Cinderella, and Ariel.
