My 4 year old is obsessed with the Disney Channel, what should I do?

Posted under Ask the Mediatrician.

Q: Recently my 4 year old daughter has found a new, almost obsessive interest in the Disney Channel shows (Hannah Montana, Wizards of Waverly Place, etc). TV was never a problem before, but now she would rather watch these shows than do anything else. I also think that these shows may be too big-kid for her. What do you think, and how can I get her away from the TV without fuss?
