From 12 months onward, your little one becomes a lot more active. Our 9-ounce straw sippy cup is ideal at this stage, designed to keep busy toddlers happy and hydrated all day! The insulated core keeps drinks cool while on the go or at play, and the soft silicone straw is gentle on little teeth and gums. In between sips, the straw flips down to prevent spills and keep your bag or the floor clean. As with most Tommee Tippee cups, you can interchange parts like lids and bases, although handles are not compatible with insulated cups. The toddler sippy cup is super easy to clean—either in hot, soapy water or on the top shelf of the dishwasher. It’s safe for steam, UV, or microwave sterilization, too.
