A child carrying device, comprising: a frame mounted on a set of wheels or castors to enable the device to be manually conveyed thereon, and a seat mounted on said frame , said device including adjustment means for selectively reconfiguring the device such that it is operable as any one of a stroller, a child back carrier and a high chair; wherein the seat is mounted to said frame by means of at least one link arm that is rotatably coupled at one end thereof to said seat and rotatably coupled at the other end thereof to said frame such that the longitudinal axis thereof is selectively angularly adjustable relative to said frame to enable the relative position and/or orientation of said seat to be selectively adjusted; characterised in that the frame comprises a pair of parallel and spaced apart side bars , each side bar comprising a first elongate section having an open tubular end, and a second elongate section, wherein said second elongate section is telescopically and slidably mounted, in longitudinal alignment, in said first section so as to be selectively retracted and extended relative thereto; wherein the device is configurable in a stroller mode with the at least one link arm extended forward of the frame at a small angle relative to the longitudinal axis of the side bars with the main frame fully extended; or in a high chair mode with the at least one link arm extended forward of the frame at a larger angle relative to the longitudinal axis of the side bars with the upper side bar section of the main frame retracted; or in a child back carrier mode with the at least one link arm extended rearwardly of the frame at a large angle relative to the longitudinal axis of the side bars with the main frame fully retracted and the rear wheels and their support legs in the folded configuration. a frame mounted on a set of wheels or castors to enable the device to be manually conveyed thereon, and a seat mounted on said frame , said device including adjustment means for selectively reconfiguring the device such that it is operable as any one of a stroller, a child back carrier and a high chair; wherein the seat is mounted to said frame by means of at least one link arm that is rotatably coupled at one end thereof to said seat and rotatably coupled at the other end thereof to said frame such that the longitudinal axis thereof is selectively angularly adjustable relative to said frame to enable the relative position and/or orientation of said seat to be selectively adjusted; characterised in that the frame comprises a pair of parallel and spaced apart side bars , each side bar comprising a first elongate section having an open tubular end, and a second elongate section, wherein said second elongate section is telescopically and slidably mounted, in longitudinal alignment, in said first section so as to be selectively retracted and extended relative thereto; wherein the device is configurable in a stroller mode with the at least one link arm extended forward of the frame at a small angle relative to the longitudinal axis of the side bars with the main frame fully extended; or in a high chair mode with the at least one link arm extended forward of the frame at a larger angle relative to the longitudinal axis of the side bars with the upper side bar section of the main frame retracted; or in a child back carrier mode with the at least one link arm extended rearwardly of the frame at a large angle relative to the longitudinal axis of the side bars with the main frame fully retracted and the rear wheels and their support legs in the folded configuration. <EOS>
