S.D.
B. - I read your post and smiled because I could have written it verbatim myself. My boys are 2 and 4 months. I did not start focusing on "going green" until my first started eating solids. I think that the media is the culprit for stressing us out about organics. Regardless, I think that we need to try and lessen the exposure of toxins to our children. The question really lies on whether what is being marketed as "organic" is in fact trully organic. I am not sure if or how we can assure ourselves that we are getting what we are paying for, but we can give ourselves peace of mind by making the effort. I really try and give my toddler as much organics as possible. Now that my 4 month old is approaching solids, and it is hard for me to keep up my breastmilk (I also work), I will start supplementing with organic formula. I will probably use Earth's Best or Similac. There is a book entitled "How to raise a smarter child by Kindergarten" that disucusses the toxins in our environment, as well as certain foods that we should focus on being organic. You are right that this is stressful...I have learned that almost everything we are exposed to has some adverse effect. I think the best we can do is to control the levels we are exposed to, especially for our little ones that are more vulnerable. The book may give you some direction on what foods are important be organic.
I hope this helps. At least know, you are not alone on the issue. I think it is worth it. Best of luck - S
