She returned to Argentina in 1956 after the Revolución Libertadora. From 1958 onwards, Walsh wrote numerous TV scripts, plays, poems, books and songs, specially dedicated to young children. She was also a successful performer, singing her own songs onstage and recording them later in albums, like "Canciones para mirar", "Canciones para mí" and "El País de Nomeacuerdo". " Juguemos en el mundo", also an album, was a satirical show for adults, which was made into a film of the same title, albeit with a story unrelated to the original stage show and songs recording. The film was based on her characters "Doña Disparate y Bambuco" and was directed by her partner at that time, Maria Herminia Avellaneda (1933–1997).
