While plopping your kid down in front of any TV can get controversial these days, there are a whole bunch of buzz killers who are completely against Baby Einstein, saying that watching could actually lead to delays in children. I'm not really sure of the reasoning because, just to have the time to read the entire article in Time Magazine would require me to put my child in front of a Baby Einstein video.
Instead, I conducted my own study -- very scientific -- with three children. 30 minutes of Baby Einstein: Neighborhood Animals allowed me to pour myself a cup of coffee, go through some bills, catch up on email and throw in a load of laundry. There was no wrestling, boys yelling "that's miiiine!" or whining. For 30 whole minutes.
And through it all, Lucy repeated "doggy" each and every time she saw one on the screen. Speech delays, schmeech delays.
