Reply to: pumping to induce labor Fran, If breastfeeding during the last months of pregnancy does not increase the levels of oxitocin high enough to stimulate uterine contractions, I doubt that a breast pump will. However, there are always exceptions to any rule and I am sure that some women can be found who will claim pumping worked. Whether their "success" may be due to a happy coincidence between time of pumping and their "natural" hormonal climb cannot be proven nor dismissed. Best wishes with your birth, NIcole Bernshaw
