Each of the four different triangle rattles makes a different sound for your baby to discover: jingling bells, clacking cymbals, chiming bells, and rattling beads are enclosed in colorful, chunky frames that are easy for your little one to grip. The four shakers can also slot together to form one big circular shaker for even more fun. Try putting two or three together in different combinations to create different sounds. Let sing a song or a nursery rhyme and shake our music maker along to the rhythm. Playing along will help develop coordination and concentration skills. It lots of fun too!
