I am actually going to do my best to keep my child's exposure to Star Wars to a bare minimum until I feel they are old enough to watch the Saga. With their arrival set for early October, that's at least a 5-7 year wait, not even accounting for the possibility of siblings.
However, once that day comes, and if I still have some internet presence, I will be chronicling the experience for you all.
I have already decided that I will be doing flashback order for their first viewing. That's VI-V-I-II-III-VI. All rewatches will be in Episode order. As far as additional material goes, if they like the Saga well enough to want more, I will make available what I can to them. This includes Clone Wars, Rebels, VII-IX, and the various EUs. While I will make my child(ren) aware that these materials have some fundamental differences, they will not be discouraged from liking whatever they wish
As a matter of fact, while I will give my personal opinion when asked, I will ALWAYS encourage my child(ren) to like what they like regardless of my feelings about the work in question. As the appreciation of the subjectivity of art is one of my core values, it is something I want t instill at a young age.
There are other values I want to instill at a young age, but that's a topic for another time.
