Meh, my parents let me watch anything (TV, internet, magazines, etc.), I turned out just fine, good grades at school, I have lots of friends, I like to dress GQ style and I'm heading off to college in a few months, honestly let the kids watch anything, I even got to watch the Playboy channel, yay! (Seriously I did).
The only thing that kids need is a good education and discipline, I cannot tell you how many times I see some brat making a scene at a mall, the supermarket or a restaurant and the parents BEG him to be quiet and stop making a mess, some even CRY! Wtf?! That's PATHETIC! And bad parenting! When I was a kid if I made a scene it was told that either I shut up and behave or I would get spanked, and trust me I did because they would do it!
Keyword here is discipline! I don't mean beat him to a pulp, just slap some sense into the kid and tell them the consequences.
