From 12 months onward, your little one becomes a lot more active. Our 9-ounce sippy cup is ideal at this stage, designed to keep busy toddlers happy and hydrated all day! The insulated core keeps drinks cool so they stay hydrated. With a soft spout that’s kind to little teeth and gums, easy-grip sides, and a trusty two-piece, non-spill valve it’s perfect for drinking on the go. As with most Tommee Tippee cups, you can interchange parts like lids and bases, although handles are not compatible with insulated cups. The sippy cup is super easy to clean - either in hot, soapy water or on the top shelf of the dishwasher. Helping you Parent On
