If there are indidgo children they are more a symptom of a greater problem such as toxicity, illness, genetic weakening, etc.
Why else would such a large percentage of 'indigo children' be autistic, ADD, sick, etc?
We can assign psychic woo-woo to all this stuff or we actually look for a real cause first. If no real cause can be found then people can fall back to the new age hype.
However, we are far from that point right now.
