What do they do in the less westernized cultures? I have heard some insist on weaning others see no problem with the combination. And don't get me started on tandem nursing. Most of my moms who do just don't tell the doctor. About this protien issue could the physician applied what we know about the pill, which mimics pregnancy, to pregnancy itself? The hormones cause lower protien levels in BM but I don't think it applies to the entire body.
