The easy way to explain it is to copy the following and if you want to look into it more, you can google it:-) I read a book on it which was interesting.
Indigo children is a label given to children whose parents believe they possess special, unusual and/or supernatural traits or abilities. The idea is based on New Age concepts developed in the 1970s by Nancy Ann Tappe. The concept of indigo children gained popular interest with the publication of a series of books in the late 1990s and the release of several films in the following decade. A variety of books, conferences and related materials have been created surrounding belief in the idea of indigo children and their nature and abilities. These beliefs range from their being the next stage in human evolution or possessing paranormal abilities such as telepathy to the belief that they are simply more empathetic and creative than their peers.
Although there are no scientific studies to give credibility to the existence of any indigo children, or their traits, the phenomenon appeals to parents whose children have been diagnosed with learning disabilities and parents seeking to believe that their children are special. This is viewed by skeptics as a way for parents to avoid proper pediatric pharmaceutical treatment or a psychiatric diagnosis which implies imperfection. The list of traits used to describe the children has also been criticized for being vague enough to be applied to almost anyone, a form of the Forer effect. The phenomenon has been criticized as a means of making money from credulous parents through the sales of related products and services.
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, stating that during the mid 1960s she began noticing that many children were being born with "indigo" auras (in other publications Tappe has said the color indigo came from the "life colors" of the children which she acquired through her synesthesia). 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. 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.
Descriptions of indigo children include the belief that they are empathetic, curious, strong-willed, independent, and often perceived by friends or family as being weird; possess a clear sense of self-definition and purpose; and also exhibit a strong inclination towards spiritual matters from early childhood. Indigo children have also been described as having a strong feeling of entitlement, or "deserving to be here." Other alleged traits include a high intelligence quotient, an inherent intuitive ability, and resistance to authority. According to Tober and Carroll, indigo children function poorly in conventional schools due to their rejection of authority, being smarter than their teachers and a lack of response to guilt-, fear- or manipulation-based discipline.
 Attention-deficit hyperactivity disorder
Many children labelled indigo by their parents are diagnosed with attention-deficit hyperactivity disorder (ADHD) and Tober and Carroll's book The Indigo Children linked the concept with diagnosis of ADHD. Their book makes the case that the children are a new stage of evolution rather than children with a medical diagnosis, and that they require special treatment rather than medications. Robert Todd Carroll points out that labeling a child an indigo is an alternative to a diagnosis that implies imperfection, damage or mental illness, which may appeal to many parents, a belief echoed by many academic psychologists. He also points out that many of the commentators on the indigo phenomenon are of varying qualifications and expertise. Linking the concept of indigo children with the distaste for the use of Ritalin to control ADHD, Carroll states "The hype and near-hysteria surrounding the use of Ritalin has contributed to an atmosphere that makes it possible for a book like Indigo Children to be taken seriously. Given the choice, who wouldn't rather believe their children are special and chosen for some high mission rather than that they have a brain disorder?"
Stephen Hinshaw, a professor of psychology at the University of California, Berkeley, states that concerns regarding the overmedicalization of children are legitimate but even gifted children with ADHD learn better with more structure rather than less, even if the structure initially causes difficulties. Many labeled as indigo children are or have been home schooled.
According to research psychologist Russell Barkley, the New Age movement has yet to produce empirical evidence of the existence of indigo children and the 17 traits most commonly attributed to them were akin to the Forer effect; i.e. so vague they could describe nearly anyone. Many critics see the concept of indigo children as made up of extremely general traits, a sham diagnosis that is an alternative to a medical diagnosis, with a complete lack of science or studies to support it. The lack of science is acknowledged by some believers, including Doreen Virtue, author of The Care and Feeding of Indigos, and James Twyman, who produced two films on Indigo Children and offers materials and courses related to the phenomenon. Virtue has been criticized for claiming to have a Ph.D when it was provided by an unaccredited diploma mill.
Mental health experts are concerned that labeling a disruptive child an "Indigo" may delay proper diagnosis and treatment that may help the child. Others have stated that many of the traits of indigo children could be more prosaically interpreted as simple arrogance and selfish individualism, and view the concept as hypocritical since many parents with certain New Age beliefs do not view these traits to be progressive.
In a Dallas Observer article discussing indigo children, a reporter recorded the following interaction between a man who worked with Indigo children, and a purported Indigo child:
“ "Are you an indigo?" he asked Dusk. The boy looked at him shyly and nodded. "I'm an avatar," Dusk said. "I can recognize the four elements of earth, wind, water and fire. The next avatar won't come for 100 years." The man seemed impressed. ”
I've always felt I've been an indigo child, even when I was young. I knew what an indigo child was too, when I was small. I had a very strong spiritual side growing up and I have no idea how I knew the things I did.
That brings us to another potential subject...how things come to us. I, also, had knowledge, and ideas come early on from ?. They came in the form of thoughts and I didn't know why. I identified with the American Indians from early on with the land being taken and them being cheated. I saw the injustice. I also identified with Negros & growing up in a small town in MN where there ZERO colored people, when I was 11 or so and a couple of girls came from Chicago, I was thrilled. I remember an analogy that I still use to this day that came to me when I was a child.....God created all sorts of flowers and a tulip is no less a flower than a daffodil or sunflower and that people are like that. A darker color makes a person no less a human being than another.
So, if you can imagine a philosophical girl spouting all sorts of things like that....lol...that was me. I loved the movie...Born Free. I used to think about what freedom really is. I didn't like that mustangs that ran freely were turned into meat. Later, when trying to write a poem, I saw us in our postage stamp yards as being in zoo's. So................when I came across the Indigo Children information, some things made sense. It goes back to the..why are we here and what are we to do? I would like to as Mother T. said...do small things with great love.
I was the child running around singing Dionne W.'s song...what the world needs now is Love sweet Love...no not just for one, but for everyone.
I agree with Mother Teresa's philosophies. She was an amazing person who accomplished amazing things and makes a superb role model.
I agree with you 100% that we are all created equal as people. There is no one that is better, nor less then who we are of ourselves. I've always thought this, even when I was a small child.
