and even casting of plays and films. In 1975, she formed Unga Klara, a branch of Stockholm City Theater for the purpose of producing theatrical performances for children and youth. Osten worked there as both stage director and artistic director until the summer of 2014 and developed a process for creating a performance. The playscript Babydrama (2006) was written by psychoanalyst and dramatist Ann-Sofie Bárány following a period of improvisation and research. This production was controversial because the intended audience was infants aged from six months. Osten had been cautioned that children this young could not comprehend a drama, but she defied critics, and, during this performance, infants, without previous theater-going knowledge, sat as a theatre audience collectively watching the play for one hour. Baby Drama is a cabaret with six actors. The narrative suggests the lived experience of the audience from conception, the time in the womb, birth, meeting with its family, and then on to a life of its own. Osten documented the reaction of the young audience in Baby Drama: A documentary film with the baby as the lens where the viewer sees infants' faces watching the performance. Osten finds this to be proof of adult significance as performers, as art distributors, and of human love for communication. She interprets the reaction of the audience as an innate need in a child for gestures, facial expressions, emotions, language, and bodies from which to learn communication. Osten’s process involves the entire theatrical company; writers, actors, technicians, mask makers, based on research and extended collaboration with audience groups. This process is influenced by Keith Johnstone’s improvisational theater. Experts outside the theater world, artists, and academic researchers are invited by Osten to contribute with their expertise to the evolutionary and improvisational process of a stage production. Osten put this method of working to the test in Baby Drama when she wanted to investigate how early an audience can be receptive to theatrical performance. Guest stage director Osten has been a guest director at theaters other than Unga Klara and in genres other than children's theater. These productions include the operetta Glada Änkan (The Merry Widow) at Folkoperan in 2008, and popular productions at Gothenburg City Theatre, such as Publiken [The Public] by Federico García Lorca and I Annas Garderob [In Anna’s closet] by Ann-Sofie Bárány, inspired by the life and work of Anna Freud. In 2014, Osten directed a major
