Our premium sippy cup has been thoughtfully designed in both form and function. The teat is 100% silicone, so it’s easy to clean and soft on little gums. A weighted straw stays in the liquid no matter which way the cup is tipped, so bub can keep drinking from any angle. When they’re ready to move on, the cup converts to an open cup. We’ve also included a free straw cleaner to keep everything fresh.
