A cart for use in supporting an infant carrier which includes an articulating frame having front and rear pairs of spaced apart and elongated members. Pairs of wheels are secured to lower ends of the elongated members. First and second latch sub-assemblies each include a pair of pivotally connected and conduit shaped bodies, these sliding over intermediate locations of the pairs of elongate members and such that the elongate members are permitted to pivot between expanded and collapsed positions. A perimeter defined frame is supported upon pivotally inter-connecting upper ends of the elongated members, the frame adapted to support the infant carrier thereupon during ambulatory traversing of the cart.
