Cheers to baby’s first cup! The Bumkins Silicone Starter Cup is a two-ounce open cup for babies uniquely made to support the transition from bottles to big-kid cups. Our two-ounce open cup design is sized for little hands with textured ridges, making it easier for babies to grip. At the same time, the sloped interior helps control the liquid flow for safer drinking as little learns to take sips independently. Markings on the transparent silicone let you measure baby’s progress, and the weighted bottom reduces tipping, meaning fewer spills for you to clean up!
