Really, the only we have banned is those darn FRED shows. That is the most foul show I have ever seen. Ick.
They mostly watch dora, spongebob, beyblades and pokemon. They only watch about 30 min a day anyways so no biggie. My 2.5 year old loves anything girly like angelina and lalaloopsy.
My teens are banned from R rated movies unless we have prescreened them. There are very few R rated movies they can watch.
