Baby Vivaldi is unfinished Baby Einstein that was set to release on October 25, 2001. The video premise was similar to Baby Mozart and Baby Bach and with more puppet shows (same concept as Baby Beethoven). The video was near to completion, But do unknown reasons, The video was cancelled, and reworked into Baby Newton: All About Shapes, Which uses the music that originally was gonna be featured in Baby Vivaldi. The video's files to episode are lost and can't be found online. The only piece of evidence is The CD (which was released on March 15, 2002, The day Baby Newton came out) Or this Wikipedia article that Julie Clark herself said "Another episode, Baby Vivaldi, was planned around late-2001, but was never finished. This later became the idea for Baby Newton.''
