I found this article on I Love Cloth Diapers (the Softbums blog.) I really thought it was a good article about the pros of breastfeeding (and even hits on the pros of extended breastfeeding.) Some days I am ready to be done breast feeding, but most days I am not. I will miss this time of closeness and nurturing with my baby. Plus the immune system benefits area awesome. Knock on wood, Destructo has only had a handful of minor little colds.
