Bumkins Silicone Straw Cup and Lid Set is designed with unique features and options to support independent drinking skills and stages. A spill-resistant toddler training cup with a sloped interior controls the liquid flow, so littles can safely take sips from a coffee-style spout on the made-to-fit lid. Or learn to drink from a straw, angled for smoother suction with a built-in stopper to prevent them from pulling it out of the cup. And with a weighted base to minimize spills, little ones can skip the straw and lid to practice open cup drinking, supporting the transition to big kid cups!
