Sip Sip Hooray! With its sleek, modern look, cheeky personality and grow-with-me design, the Happy Sippy guarantees a smile. One of the first sippy cups made entirely of food-safe silicone, the simple 3-piece design is durable, unbreakable, leak-resistant, and mold-resistant. Less is more with our new design. The simple silicone cup and lid design is all you need and nothing you don’t… well, except for the handles. Those come in handy for littles learning how to drink on their own.
