I kind of agree with what BellaBambina is saying - if a family watches a lot of TV (and I have no idea how to define 'a lot' it's all relative lol!) then it will be on more and the kids will watch it more.

DP and I don't watch heaps of TV. We do watch it but not every day and it's not on during the day much at all. As a result, DS doesn't watch much. He has just recently in the last couple of months started watching In the Night Garden of an evening, but not every day. This is because he loves it and it's on at the right time of day 5:30pm, for myself or DP to get dinner cooked without grumpy whinging. Other times I will put a Wiggles DVD (thanks Bella!!!) on or Seseme street so I can grab a quick shower before he notices I'm gone

I think that TV is part of the modern, Western lifestyle and it can be quite difficult to avoid it. Kids are going to be exposed to it sooner or later. Parents will all make choices about how much TV their kids watch (and what they watch) that they are comfortable with.
