Babes in Toyland is an operetta composed by Victor Herbert with a libretto by Glen MacDonough, which wove together various characters from Mother Goose nursery rhymes into a musical extravaganza. Following the extraordinary success of their stage musical The Wizard of Oz, which was produced in New York beginning in January 1903, producer Fred R. Hamlin and director Julian Mitchell hoped to create more family musicals. MacDonough had helped Mitchell with revisions to the Oz libretto by L. Frank Baum. Mitchell and MacDonough persuaded Victor Herbert to join the production. Babes in Toyland features some of Herbert's most famous songs – among them "Toyland", "March of the Toys", "Go to Sleep, Slumber Deep", and "I Can't Do the Sum". The theme song "Toyland", and the most famous instrumental piece from the operetta, "March of the Toys", occasionally show up on Christmas compilations.

Victor August Herbert was an American composer, cellist and conductor of English and Irish ancestry and German training. Although Herbert enjoyed important careers as a cello soloist and conductor, he is best known for composing many successful operettas that premiered on Broadway from the 1890s to World War I. He was also prominent among the Tin Pan Alley composers and was later a founder of the American Society of Composers, Authors, and Publishers (ASCAP). A prolific composer, Herbert produced two operas, a cantata, 43 operettas, incidental music to 10 plays, 31 compositions for orchestra, nine band compositions, nine cello compositions, five violin compositions with piano or orchestra, 22 piano compositions and numerous songs, choral compositions and orchestrations of works by other composers, among other music.
