Doo, doo, doo, doo, doo, doo keep drinks cool and encourage hydration with a Baby Shark Insulated Sippy Cup! This sippy cup features insulated cup walls to keep drinks cool for longer and is great for families on the go. The silicone valve helps control the flow of liquid and prevent leaks so that the drink stays inside the cup and off of your own little baby shark. This line of sippy cups was developed with a Pediatric Feeding Specialist and each features a bite-resistant hard spout that is better for your child's developing teeth. The shorter spout size also makes the transition to an open cup smoother for your child. Kids will drop things, but each sippy cup lid has a DropGuard™ bumper that helps prevent breakage. That's SHARKtastic! And when the cup is empty, the dishwasher safe design makes keeping it clean simple.
