A baby walker is equipped with a device that produces a sound, such as musical tones, when it is moved about a floor surface. The walker may be moved in response to the urgings of a baby within the walker, or in response to the urgings of another person pulling the walker via a pull-cord detachably connected thereto. The device for producing sound may be a trail-along toy, such as a wheeled xylophone, or may be built into the wheel assemblies of the walker. A cord attaching the trail-along toy to the walker may be grasped by the infant and pulled, without any motion of the walker, to produce a sound. Each wheel of the conveyance is suitably fitted with a sounding device, which may produce a different sound for the turning of each wheel.
