Abstract
A disposable absorbent article including a wetness sensation member and visible highlighting indicating the presence of the wetness sensation member to facilitate an opportunity for the toilet training of the wearer. The wetness sensation member includes a permeable layer and a flow control layer. Urine deposited on the wetness sensation member can penetrate through the permeable body-facing layer in a z direction away from the wearer to the flow control layer. The flow control layer retards the passage of the urine through the wetness sensation member in the z direction while supporting the movement of the urine in an x-y plane to increase the wetted area contacting the wearer's skin and thereby enhance the wearer's awareness that urination has occurred. The visible highlighting is visible when viewing a body-facing surface of the article and may be associatively correlated with an externally visible marking and/or with the concept of toilet training.
