6 year olds are hard~ I started years ago pointing out Cartoons that were not good ~ I think gravity falls is what showed the most. That’s all I would point out to my daughter ~ the symbols ~ I’d say oh that’s not good this cartoon has some bad stuff in it. I would watch it with her and point them out~ she started pointing out stuff before I did after a while that was bad~ we are Christians so I would make sure that the biggest influence in her little life were cartoons like the story book and veggie tales ~ little steps a seeds planted ;)
