Abstract: A toy toilet training system utilizes a kit to teach children toilet skills. The kit includes a doll that receives a fluid, such as water, through a mouth opening and can discharge the fluid from an outlet to simulate urination. A toy toilet, sized in proportion to the doll, has a bowl portion to receive the discharged fluid, and a decorated sheet of dissolvable material is sized to be placed in the bowl portion. When the fluid is discharged onto the sheet, it disappears, thus making the simulated toilet event of greater interest to the child. The toy toilet preferably has a ledge in the bowl interior to support the sheet, and a drain opening with removable drain plug facilitates cleaning. The kit may also include toy training pants, with pull-ups loop tabs, a toy bottle for the fluid, and an instruction/storybook. Preferably, a plurality of dissolvable sheets are provided in the kit and are packaged in a matchbook style packet.
