When it's time to leave the bottle behind, be prepared with the C'est Silicone! Training Cup with Straw. Made of 100% food-grade silicone in soft hues, this first cup is easy on delicate gums and easy on your eyes, too. The modern convertible design meets early sippers exactly where they are - going from lidded straw cup to open cup is a breeze. Cheers to cups that pull double duty and make transitions better for all!
