A child carrier apparatus comprises a support frame, a backrest assembly having a backrest frame, a seat assembly mounted with the support frame, wherein the seat assembly includes a first seat frame and a second seat frame, the second seat frame being operable to rotate about a pivot axle relative to the first seat frame, and a hinge structure connected between the backrest frame and the first seat frame. The hinge structure blocks rotation of the backrest frame when the second seat frame is deployed for use, and access to the second seat frame is disabled when the child carrier apparatus is in a configuration using the first seat frame for seating a child. In some embodiments, a method of operating the child carrier apparatus is also described.
