While not a parent myself, I did try to get my niece to watch anime, but have only succeeded in getting her to enjoy Miyazaki films. I'm still hoping that she will eventually get into it somewhat more, but I won't hold my breath.
However, I will have a new nephew in a few months that I hope I can corrupt, er, introduce anime to in a few years.
PS. Well, at least now I know that Graham is the same age as me!
