My kid is obsessed with the Cindy-Lou Who design, and I love that the 9oz size is just right for her little hands without being too heavy. The silicone straw has held up to some serious chewing without a single crack, which is more than I can say for other cups we've tried.

The 9oz size is perfect for my toddler's small hands, and the silicone spout is gentle on her gums. She actually drinks more water now since she loves the silly Cindy-Lou Who face peeking up at her. It survived its first drop onto the tile floor without a single dent.

My little one got so excited seeing the Cindy-Lou Who design on this tumbler—the 9oz size is just right for her small hands, and the silicone makes it easy to grip without slipping.
