Just to throw another variable in the air.............Could these children be the offsprings of abductees?
The term "indigo children" originates with parapsychologist and self-described synesthete and psychic, Nancy Ann Tappe who developed the concept in the 1970's. Tappe published the book Understanding Your Life Through Color in 1982 describing the concept,[1] stating that during the mid 1960s she began noticing that many children were being born with "indigo" auras[2][3] (in other publications Tappe has said the color indigo came from the "life colors" of the children which she acquired through her synesthesia[4]). The idea was later popularized by the 1998 book The Indigo Children: The New Kids Have Arrived, written by husband and wife self-help lecturers Lee Carroll and Jan Tober.[5] The promotion of the concept by Tober and Carroll brought greater publicity to the topic, soon their book became the primary source on "indigo children". They describe the goal of indigo children to be a remaking of the world into one lacking war, trash and processed food.
In 2002, an international conference on indigo children was held in Hawaii, drawing 600 attendees, with subsequent conferences the following years in Florida and Oregon. The concept was popularized and spread further by a feature film and documentary released in 2005, both directed by James Twyman, a New Age writer.[6]
Susan W. Whedon suggests in an 2009 article in Nova Religio, that the social construction of Indigo Children is a response to an "apparent crisis of American childhood."[2] Whedon explains that the crisis is evident in the increase in "diagnoses of ADD and ADHD in American children" and "heightened awareness of youth violence" caused parent to "take matters in their own hands."[2] Parent began self-medicating self-diagnosing their offspring as Indigo Children as means of "redeeming"[2] them for their improper behavior stemming for ADD and ADHD.[2]
