A collapsible infant carrier apparatus comprises a support frame including front and rear leg frames and a handle, and a linkage frame pivotally connected with the front leg frame and the handle. A first latch mechanism is connected between the handle and the linkage frame, wherein the first latch mechanism is operable to lock the handle in position relative to the linkage frame. A second latch mechanism is connected between the linkage frame and the front leg frame and having a locked state and an unlocked state, wherein the second latch mechanism when in the locked state locks the linkage frame with the front leg frame, and the second latch mechanism when in the unlocked state enables rotation of the linkage frame relative to the front leg frame. The infant carrier apparatus can be collapsed by rotating the linkage frame.
