What is claimed is: 1. An absorbent article adapted for wearing about the lower torso of a wearer, the absorbent article having a chassis, the chassis comprising: a topsheet; a backsheet attached to at least a portion of the topsheet; and an absorbent core disposed between the topsheet and the backsheet, wherein the absorbent article further comprises a wetness event counter attached to the chassis and which is adapted to provide a different signal for each of a plurality of wetness events experienced by the absorbent article; wherein the wetness event counter comprises a component which becomes more permeable in the presence of urine, and one or a plurality of wetness indicating members, each of the members comprising a reactive element and a non-reactive element that precludes premature activation of the reactive element by urine of each successive wetness indicating member. 2. The absorbent article of claim 1, wherein the wetness event counter comprises a single indicating member which comprises a plurality of reactive elements. 3. The absorbent article of claim 2, wherein the reactive elements comprise a urine sensitive component and an indicating component. 4. The absorbent article of claim 3, wherein the indicating component comprises a plurality of particles suspended in the urine sensitive component such that the indicating component provides a visible indication when the urine sensitive component is activated by urine. 5. The absorbent article of claim 1, wherein a first wetness event is capable of activating a first indicating member thereby causing the first indicating member to provide a first signal, and wherein a second wetness event is capable of activating a second indicating member thereby causing the second indicating member to provide a second signal. 6. The absorbent article of claim 5, wherein the reactive element comprises a urine sensitive component and an indicating component. 7. The absorbent article of claim 6, wherein the indicating component comprises a plurality of particles suspended in the urine sensitive component such that the indicating component provides a visible indication when the urine sensitive component is activated by urine. 8. The absorbent article of claim 5, wherein the non-reactive element of the second indicating member can absorb moisture from the first wetness event and subsequently dry out forming fissures therein such that moisture from the second wetness event can pass through the fissures. 9. The absorbent article of claim 8, wherein the nonreactive element is selected from the group consisting of: montmorillonite clays, forisomes, and cross linked polyacryates with montrnorillonite clay. 10. The absorbent article of claim 5, wherein the first indicating member comprises a counter-acting element, wherein the second wetness event is capable of activating the counter-acting element thereby causing the counter-acting element to modify the first signal from the first indicating member. 11. The disposable absorbent article of claim 1, wherein the wetness event counter is disposed on at least a portion of the topsheet. 12. The disposable absorbent article of claim 1, wherein the wetness event counter is disposed adjacent to an inner surface of the backsheet.
