When I say tv-free I'm really thinking of television, cable, dvds, videos and I'd throw video, hand-held and computer games in there too.
Having said that, I don't make the cut.
My older dcs watch dvds on my computer from time to time. It's a treat and it's rare but it does happen.
We don't have a television so I'd call myself tv-free as a short hand, but my kids do have some screen time--a few hours a month probably but it is insidious and does creep up to weekly sometimes.
Good luck with your tv-free goal. We've been holding at the above amount since my oldest was 3 (we were at zero before that) and I think my kids are happier and healthier for it. So I think it is worth the inherent challenges.
Happy mom to DS2000, DS2002, DD2004, DS2006 and DS 10/2009:
