Yes, this can be done with any age, I just believe that instilling the behavior when they are very young will hopefully stick with them. I am dealing with this in my personal life with my 9 year old and it would be great to have it all reiterated in her school enviornment and for young kids not to already have the technology that is wasting away braincells. It is reality however so we need to deal with it in a productive manner. Thanks for your work!!
