Kids Watching T.V. Good or Bad?

I think that limited television is completely fine. My aunt gets really upset that I let my 2 year old watch tv, but I do not see the harm in it. I don't let him watch anything horrible, just sesame street, dora or blues clues. I would rather him watch something like that, than the cartoons that we used to watch when we were kids. At least these are educational, and I can get in a shower or finish dinner when my child is being clingy.
