Infant carriers are stably supported and transported by being positioned on a frame set on wheels. The frame may include an infant carrier holder with a floor with a ramp and sidewalls. The infant carrier holder may be integral with the frame or may be mounted to a mounting device that can be adjusted for mounting angle or height. A handle is provided to the frame at a position that is suitable for a person in a wheelchair to grasp the frame and move the transport. A handle suitable for a standing person to grasp the frame may optionally be provided. The transport permits a person that may have difficulty carrying or transporting an infant carrier to more easily transport the infant carrier in a standing or a seated position, the latter as may be the case with a wheelchair occupant. The transport may be fastened to the wheelchair.
