Abstract
Abstract A disposable diaper has a separable panel formed in its front portion over the umbilical area of an infant. The panel has at least one separation line for opening the panel to expose the umbilical cord of a newborn infant and allow it to project therethrough. When the umbilical cord has been eliminated, the panel can be left intact to allow full use of the diaper.
