A toilet training wetness indicator for alerting a wearer to urination and a garment incorporating such an element. The toilet training wetness indicator, which may be an insertable wetness indicator or integrated directly into a garment, such as training pants, comprises a liquid permeable enclosure having a liquid absorbent body enclosed therein. The liquid absorbent body absorbs liquid within the pants and applies hydraulic pressure to the enclosure upon absorption of a preselected amount of liquid. The enclosure limits expansion of the absorbent body so that the wetness indicator stiffens as liquid is absorbed. The wetness indicator has a first stiffness and is relatively pliable when dry and a second stiffness greater than the first stiffness upon absorption of the preselected amount of liquid.
A wetness indicator for alerting a wearer to urination comprising a liquid permeable enclosure having a liquid absorbent body therein, said liquid absorbent body absorbing liquid in the presence thereof and applying hydraulic pressure to the enclosure upon absorption of a preselected amount of liquid, said enclosure limiting expansion of the absorbent body so that the wetness indicator stiffens as liquid is absorbed, said wetness indicator having a first stiffness when dry and a second stiffness greater than said first stiffness upon absorption of said preselected amount of liquid.
A garment comprising an inner surface facing a wearer when wearing the garment, and a wetness indicator positioned relative to the inner surface for alerting the wearer when the inner surface becomes wet with liquid, said wetness indicator having a first stiffness when dry and a second stiffness greater than said first stiffness upon absorption of said preselected amount of liquid.
