If this will encourage you at all, here is my experience: I had severe postpartum depression. I knew what it was, with my second child, and my OB prescribed Prozac for me within three weeks of the birth. I also breastfed exclusively for the first five months, and eleven months altogether. My doctor assured me that the risks of PPD were much higher than the risks to the baby from the antidepressant. My daughter never had a moment's trouble from it, never one side effect that I could see. She is nearly five now and a perfectly healthy, strong child. The benefits of the med, to me, were completely worth it. Hang in there.
