The book by Dr. Greene (funny, isn't it?) which is called something like "Raising Baby Green" (I'm not home for the holidays so I can't recall and can't reference the actual book) was my first venture after DD was born. It's really great and not super techy...just simple language and some good resources. I look forward to the answers to this question since I'm looking for my next green read.
On a similar note, I just picked up Good magazine and loooove it. It's a magazine all about doing good which includes environmental issues. I've found some cool websites and articles already. I'm about to check out their site http://goodmagazine.com
Oh and you had asked in response to my post about disposing of old non-green cleaners, I ran into the same dilema. To reach a happy medium, we gave our old products out to relatives or friends who would use them as long as they didn't have kids in the home...just a thought!
