This Philips AVENT 9oz My Penguin Sippy Cup is the ideal drinking solution for the growing toddler. Thanks to its advanced patent-pending valve, the cup is leak-proof ensuring mess free drinking -- Moms confirmed. The hard, bite-resistant spout is angled and designed to help toddlers take their first sips easily without tilting their head back too much, allowing the little one to develop a natural drinking position. Trainer handles are seamlessly integrated into the cup's unique penguin shape, and are there to help the toddler hold the cup and drink independently. These handles are not only shaped for little hands to grasp easily, they are also designed for anti-slip with soft touch grips. The My Penguin Sippy Cup is made from BPA free materials and includes a protective hygiene cap to keep the cup and its contents clean. For versatility, this cup is compatible with the Philips AVENT Natural and Classic bottle range, as well as the My Natural trainer and My Classic trainer.
