Cinderella,
Having your kids appreciate Yiddishkeit by exposing them to garbage (yes, Nick is garbage) is not only dangerous, it’s also the cheap way out. Let them see the beauty of Yiddishkeit for itself, not relative to other, false ideologies.
If you think you won’t harm your kids by letting them watch TV, no matter the rating, you’re making a big mistake. Their values are so far from Torah values that it’s impossible for there not to be bad hashkafos , even in seemingly innocent, “children’s” entertainment.
Now, instead of copping out, instill in your children a pride in their Yiddishkeit and an appreciation for it’s beauty, so that when temptation comes, they will not succumb.
