TV watching with M+P

So lately I have run into a few parents who have said wow I learned about this via this kids show and that kids show and I think to myself...are you really sitting there on the couch with Jr. while they watch TV?? I must be horrible, I toss Jr. in front of the TV so I can clean up, go pee or get a few minutes of me time, I don't sit there with them.. Does that make me a bad parent? I feel guilty enough about using the TV as a babysitter now I feel even more guilty about feeling guilty about how I'm using it.. Ahhh Mommy guilt will it ever stop!
