Thanks for the comment! Yes, for some time formula was accepted as a suitable substitute because people did not know the details. Now that everything is emerging about contaminants, there is a huge movement towards breastfeeding. Though I know sometimes for one reason or another formula is the only option. I actually had to feed formula to my infant for 5 days when she was 2 weeks old because she was diagnosed with a milk protein allergy. I had to eliminate all dairy from my diet before I could resume breastfeeding. Although, to make you feel better, breast milk has all kinds of contaminants in it as well because we live in a polluted environment (water, food, air). So don't feel bad :) I'm sure if the US Public Health officials educated people better on the subject, more women would have breastfed. Fortunately that is all changing, undoubtedly breastfeeding is the only food that can give the nutrients, antibodies, and digestive enzymes that are perfect for an infant. Ok, I'll stop rambling now, I'll just have to write a review on breastfeeding!
