ABSTRACT:
An infant development toy comprising a plurality of rings of varying diameter connected to each other and to a central object by a flexible connecting means. Optionally, the connecting means may be extended outside the rings to form a primary handle, and a bell may be contained within the central object or the primary handle. The rings and central object are of a size, and are spaced along the connecting means in such a manner that, when the toy is held aloft by and suspended from the point of connection of the largest ring and the connecting means, the rings are concentric and surround the central object.
