We created the Oxo Tot 360° cup for tots who are almost ready for big-kid cups. The 360-degree lid has a clear disk that adjusts to three different slow-to-fast flow rates to mimic grown-up cups. The lid helps little ones learn how to hold and tilt cups just right, and it'll spill just a little if over-tipped to teach the importance of being careful. The comfy grip is non-slip, and the dimple in the disk creates space for little noses. Once your little sipper masters those skills, the disk can be removed, and the trainer becomes a regular cup. The cup is crystal clear so you can see how much is left and has measurement markings so you can track what you're pouring in . Comes in pack of two. Dishwasher safe.
