An apparatus and method for a foldable child containment system can include an infant or child's playard. The playard can include a top rail support assembly and a bottom rail support assembly defining the top and bottom of a playard enclosure. A hub assembly can be coupled to the bottom rail support assembly. Corner posts can operably couple the top rail support assembly to the bottom rail support assembly. The top rail support assembly can include one or more rail locking mechanisms to lock and unlock a pair of top rail members from folding. Release mechanisms can be coupled to a rail locking mechanism and to the bottom rail support assembly. When the hub is lifted, the bottom rail support assembly rotates with respect to the corner posts and creates a tension in the release mechanisms that adjusts the rail locking mechanism from locked to unlocked configuration.
