The Ludi rattle is the ultimate calming and relaxing toy for the infant. It is an entirely educational toy, since it mainly helps to develop visual, motor and auditory skills. Through its use, the child learns eye-hand coordination and the action-reaction relationship, since every movement produces sound. In addition, the child discovers the world of colours and shapes, information that can be processed through touch and sight. Finally, it is a highly interactive game that arouses the childs interest while keeping him busy for hours on end.
