A foldable napper accessory for a child's playard positions an infant to minimize the risk of falls. The napper frame is foldable from a generally planar deplyed orientation about one or more generally longitudinally extending frame folding axes. The ends of an elongate support leg are pivotally connected to opposing side rail members of the napper frame and configured to be foldable about a leg folding axis generally transverse to the frame. Pivoting about the leg folding axis angles the support leg from the plane of the deployed napper frame or aligns the leg with the plane of the napper frame for stowage. An intermediate folding joint is provided in the support leg which includes intermediate axis generally perpendicular to the leg folding axis that allows folding of the leg only when the leg is folded into a specific orientation.
