You asked for encouragement, so here it is:
My husband is a workaholic who travels constantly for his job. We have 4 kids and lots of projects and time-consuming things going on. However, my DH and I talk a lot and I think we do have enough time fore each other. Mainly this is because we don't have a television luring us away from each other. Every evening that he is home we are in conversation, even if we are both working on our own things. If we aren't too busy, we light candles, make something delicious to snack on and talk for hours. So if you are thinking that your marriage will be enriched if you cancel your cable, I would say I'd bet it would.
Many first-time mothers with newborns complain that they no longer have time for themselves. While I can't say I didn't feel this at all, I do think I did find times in the seams--when the babies were napping, or contented in a bouncy seat or looking out the window, or nursing--when I could pursue things that were of interest to me. Because I wasn't always filling those moments with the tv, I think I was more enriched as a new mother than I might have been.
Finally, I think that the less tv we watch the less money we spend, the less we compare our selves to others and the more energy we have.
Having said all this, I'll confess that I do watch dvds on my computer when I am on my stationary bike. I would go batty on that thing if I didn't. I get the dvds for free from the library and I tend to watch face-paced, moronic, and often violent tv series--Battlestar Galatica, 24, Alias, to name a few. ust mentioning this in the interest of full-disclosure.
Good luck with the decision, and with the new baby.
Happy mom to DS2000, DS2002, DD2004, DS2006 and DS 10/2009:
