You're better off reading a book to your kid, for free from the public domain, a public domain on which most of Disney's work is based. And you can thank Disney, amongst others, for the perpetually increasing copyright extensions which does mean that copyright works that happened after 1923 may never enter the public domain. So yeah, your few bucks spent on a bunch of shitty cartoons is used for lobbying.

And yes, my kid also likes Disney cartoons. It's innocent fun. But let's not fall over yourself with praises on the virtues of copyright. All moral justification for it fails in light of the ever expanding copyright terms. End of story.
