Abstract
A wearable article useful for facilitating toilet training is provided. The wearable article includes a wetness sensation member held in close contact with a wearer's skin during use that enhances the wearer's awareness that urination has occurred. The wetness sensation member includes a permeable layer and an impermeable layer. During insults of urine, the permeable layer allows urine to penetrate in the z-direction and provides a medium for the flow of urine in the x-y plane via wicking. The impermeable layer supports the flow of liquid between the permeable and impermeable layers and retains the liquid thereby increasing the wetted area contacting the wearer's skin.
