Child carriage with linkage for transitioning the child carriage to a folded configuration

In one example, a carriage for pushing a child carrier has a wheeled frame that transitions between expanded and folded configurations. The frame has first and second leg assemblies and first and second linkages. The first leg assembly has a first front leg and a first rear leg that are pivotably coupled to one another. The second leg assembly has a second front leg and a second rear leg that are pivotably coupled to one another. The first linkage is attached to the first front leg and the first rear leg, and the second linkage is attached to the second front leg and the second rear leg so as to guide movement of the front and rear legs as the frame is transitioned between the expanded and folded configurations. The first and second linkages each define a support surface that supports an underside of the child carrier.
