Change in Habits

When I first began considering fostering, I was thinking about all the things that will have to change in my life. When I get up and get ready for the day, I will have to wake up and get ready a child too. I will have to make the child breakfast and maybe pack a lunch. I will have to park somewhere else so the child can get into my car... on and on throughout the day I thought of these things. But there is something that I didn't consider too much that I might have to change.
I have noticed this just recently about my television watching habits. I watch a lot of shows that are drama, now I gave up CSI a long time ago, but shows in that thread I enjoy, Chuck, Lie to Me.... Or on a lighter note, I like Big Bang Theory and How I Met Your Mother. But I would not want a child to watch any of these. They would be scary, or might resonate too closely to their experience, or just reference activities that are above the level of appropriateness for the child's age. It's the summer now, so most shows are over, but I wonder what I am going to have to give up on in the fall? I record these shows; what keeps the child from pressing play on the DVR? Well me, yes, but I don't want to be just a rule enforcer, to say "I have a long list of shows that are okay for me, but not for you." No, I'd rather skip House and watch Nemo instead.
