I called the SSY Freemont center in Northern California from the website
http://www.ssy.org/isp.html that was provided by AD. The person incharge said that, they don't have any classes for kids. They provide classes only for adults. They just finished one class and are not sure when the next class will be started. In the classes here they teach pranayama, what kind of food to eat etc...
I asked him if he had any material for kids. He said that, it can be obtained from India, by emailing them.
That's the scoop...
