I decided to post this under Life With a Babe because it the age at which little ones start to watch tv (as in, watch regularly) has dropped to four months. If there's a better area, please feel free to move it, moderators!
Very interesting video at the link above. He talks about how regular television viewing (and the type of shows being watched) changes how the brain works--and not for the better! The type of show being watched has an effect too--he talks about fast-paced shows like Powerpuff Girls, even Baby Einstein, versus slower programming like Mr. Rogers.
Thought the Mothering community would be interested.
How is TV handled in your house? We don't have cable, but we do watch movies on DVD and on Netflix occasionally. Mostly after DD has gone to bed now, since she's at the point where she wants to see the screen. (When she was younger, I used to be able to watch some X-Files as she nursed to sleep.) I'm okay with DD occasionally seeing a television, like when we're visiting family who have it on, but I won't let her stare at it for more than a couple of minutes. DH will shield her eyes from it so she doesn't even catch a glimpse. He came from a family where they weren't allowed to watch TV as children, so the 'TV is bad' mentality is more engrained in him, I guess. DD is six months old, btw.
