That's what a DVR or Tivo is for! We record what we want to see and watch it when the boys are in bed, napping, playing, at preschool, wherever...or on the weekends when people are "out". If you're watching a show that your child can't see during the hours your child is up....yeah, you're letting them know you've made a choice and the choice is to close your door and ignore the family for awhile. We put the boys to bed, grab some M&Ms or nachos, and cuddle up to watch our shows when we can, and hooray for that convenience! It's also a chance to cuddle or trade massages, or play scrabble at the same time. Something to hang out together, after the kids are engaged or asleep. If you "must", especially if your children are old enough for video games, I suppose...I would suggest a TV in a den, office, guest room, something else.....but NOT your bedrooms! Our bedroom is for sleeping or loving...or sometimes talking with no interruption. It's our "sacred place" where there are no children, TVs, or a phone with a ringer on, no toys on the floor, etc. We love our room...but are rarely in it!
I've written about this before, but my family DID drift apart and finally dissolved b/c of TVs everywhere, and everyone was separate. It didn't happen immediately, but it snuck up on us all; by the time people started realizing it the habit was there and it was too late. It was in my "deal breaker" talk we had before getting married, lol, and he's fine with it.
