I'm acting to limit my daughter's exposure to TV, and this is a topic I'd like to make a more substantial post on, but until that happy moment, I'd just like to note that: "The real World often has a slight liberal bias..."
edit: just sneaking a few minutes on HN while she watches Nihongo Quick Lesson on NHK (via Roku). Only a few shows actually really engage her, but this is one of them... She shouts and dances with the Mime guy for example.
I think as with most things, the key is moderation, and a couple of hours of TV seems unlikely to do substantive harm in the context of a day that involves lots of play in the nursery, lots of reading with daddy and mummy, running about in the yard for an hour etc.
