Abstract: A portable modular enclosure used for a baby in a porta crib or play yard. The enclosure has four panels made of mesh material with a flexible frame so that a baby will not be able to clearly see through the panels. The enclosure is constructed of four panels removably connected by snaps, zippers or other connecting means. All our panels fold down to a size which can be inserted into a single carrying case for transportation. The front panel has a flap cut into the panel providing access to the enclosure which can be closed shut or suspended in the open position with VELCRO.
