Abstract: A diaper comprising an essentially rectangular panel of flexible material having an outer layer and an inner layer to define an internal pocket. Flexible arms extend outwardly from opposite longer sides of the panel adjacent a shorter edge, each of the arms having fasteners for releasably engaging a single corresponding fastener centrally located on the outer layer of the rectangular panel. Absorbent padding material is located in the internal pocket and is of an initial width and thickness to ensure that the wearer of the diaper is maintained in the lithotomy position or an approximation thereof by the absorbent padding bearing on the inner faces of the infant's thighs. Elastic strips are located parallel and adjacent the longer sides of the rectangular panel to seal the panel about the legs of the wearer and to prevent slippage of the diaper.
