OXO - OXO Tot Training Cup 7 oz - Pink 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.
