In one example, a travel system has a child carriage and a child carrier that removably couples to the child carriage. The carriage has a frame and wheels attached thereto. The carrier has a frame or body that supports a child therein, a handle coupled to the frame or body, a handle rotation lock, and a handle extension lock. The handle extends, retracts, and rotates relative to the frame or body to different rotational positions. The handle rotation lock selectively locks the handle in each of the rotational positions, and the handle extension lock selective locks the handle in extended and retracted positions. The carrier can have (i) a rotation stop that selectively blocks rotation of the handle when the handle is extended and/or (ii) an extension stop that selectively blocks extension of the handle when the handle is in a position for hand carrying the carrier.

In one example, a child carriage has a frame with wheels. The frame has a coupler that removably couples the child carriage to a child carrier, such as a seat or bassinet. The frame has first and second leg assemblies, each having a front leg and a rear leg that are pivotably coupled about a first axis. The first crosspiece extends between the front legs of the first and second leg assemblies, and the second crosspiece extends between the rear legs of the first and second leg assemblies. The carriage is devoid of any push handle that extends above the child carrier. The frame folds about (i) the first axis from an expanded configuration to a first folded configuration so as to align hinges of the first and second crosspieces along a second axis, and (ii) the second axis from the first folded configuration to a second folded configuration.

In one example, an organizer removably couples to a handle of a child carrier. The organizer has a tray, a storage container, and a flexible material. The tray has an opening that extends into the tray's upper end towards the tray's lower end and that can receive an item for storage. The storage container is disposed below the tray and has an open upper end and a closed bottom end. The flexible material is coupled to the tray and the storage container. The organizer transitions between an expanded configuration in which the flexible material defines sides of the organizer between the tray and the storage container, and a compact configuration in which the tray and storage container are positioned closer to one another. In another example, the child carrier has a handle that extends and retracts and that prevents installation of the organizer when the handle is extended.
