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.This grow-with-me cup was designed with the future in mind! Just pop off the handles when your little is ready to grip the cup and when you're ready to really take the training wheels off, pop off the lid for open cup drinking! We'd love to take all the credit behind the simple, but powerful design, but we worked with an occupational therapist to make sure we got this model perfect for your little ones. Cheers!
