It's amazing how time flies, and your once-tiny baby will soon be running rings around you! Our 10-ounce sports bottle is the perfect large-sized sippy cup for when your toddler needs to drink more fluids. With its chunky design, easy-grip sides, and spill-proof spout, your little one will love reaching for a drink. As with most Tommee Tippee cups, you can interchange handles, lids and bases. The two-piece valve is easily removed for cleaning, and all parts can be washed in soapy water or in the dishwasher (top shelf).
