A cart includes a chassis and attached wheels; an upper basket attached to the chassis; and a lower basket attached to the chassis. In some embodiments, the cart includes no widthwise push bar in a rear of the cart such that access is unobstructed to the upper and lower baskets from the rear of the cart by a person. In some embodiments, the chassis defines on each lateral side of the cart a pair of vertically spaced handles, each handle surrounding and defining an opening. The handles preferably include handle bars shaped in an oval. On each cart side a curved elongate member extends between and connects the handles, and the curved elongate members represent the rearmost part of the cart. The rear area of the upper basket defines a seat for an infant, and a rear ledge of the lower basket defines a seat for a toddler.
