OXO - Help ease the transition from sippy to regular cup with the OXO Tot Training Cup. A translucent lid insert with perforations around the perimeter controls the flow of liquid when your child tilts the Cup to drink. A tipped Training Cup will also spill more gradually to minimize messes during the learning process. When tot is ready, remove the perforated lid insert and the Training Cup converts to a regular Cup. Soft, non-slip grips are easy for little hands to hold and the translucent Cup shows just how much is left. All OXO Tot Sippy, Straw and Training Cup lids are interchangeable.Help ease the transition from sippy to regular cup with the OXO Tot Training Cup.
