My wife being raised mostly by her Swiss mom and Swiss Grandparents has her head on differently on what is ok for the little ones to watch compaired to most I'd wager.
The super scary stuff she screens, but on National Geographic a Stallion gets a milking down for Artifical Insemination, or adult theme stuff usually gets a pass.
Dirty Jobs has some rank episodes,, pass.
Discovery Health some brutal stuff,, pass.
Seems OK I guess, damfino.
What do you screen from the kids?
