I started last year, when my daughter was in first grade. MLP aired two episodes in the morning, then we started watching it on net flix. I feel in love with the cartoon. I really enjoyed the child friendly stories, that did not talk down to the audiance. I also loved the strong compassionate characters. The songs enhanced the show, instead of being annoying.
I bought as many of the 2 inch mini figures as I could, and really enjoyed playing out stories with my daughter. We love the comic books, and really enjoy my little pony together. I hope it continues on for a long time. We are actually going to Everfree NW this summer. I am not sure which one of us is more excited.
