this is the same info i've heard in many different places...i saw a presentation locally about this that talked about most of this info...i have also help many many chats on my site www.mommychats.com with the same info presented by experts.
this is a very well put together, very well represented presentation. i recommend taking the time to watch the entire video. its long, but very eye opening and well worth it.
*sigh* just makes things much more complicated, doesn't it?
