They can watch them over and over, forever and ever...
My kids are totally into Spongebob Squarepants, Danny Phantom, and Fairly Oddparents.
Oh man, the TV doesn't get turned from Nickelodeon until we have to tear them away to do homework, bathe, go to bed, etc.
Do you have the same problems with your kids? How do you get them away from the TV once they get started? I'm no pushover, and I do get my way over them eventually. But is there a way to get them off the TV without being the bad guy?
