Michael--
Most kids want to imitate what they see their parents do, they want to be just like them. If your kids see you PhotoReading and see that you are having fun at it, they'll want to do what daddy is doing. Alex's suggestion is a perfect one by starting with Dr. Suess Books and rhymes. Altough you may want them NOT to PR in front of their teachers, especially in elementery school.
I do not know if the Canadian school system allows a child to skip grades, but who knows?
if they do, with PR your children could have their Bachelor's or Master degrees by the time their friends are entering highschool.
