Re: pumping before birth
with mammal. Keep in mind though that like any induction technique, nipple stimulation will not put you into labor unless your body is already headed that way. It may speed labor up or give it a nudge to get going, but it won't start it on its own.
Which is not to say it is safe to pump before birth, especially for a first time mother or a mother who isn't still nursing an older child (she would have built up a tolerance to the level oxytocin produced when she nurses). Nipple stimulation causes your body to produce oxytocin, which is the natural form of pitocin, and just like pitocin it can cause very strong contractions or continuous contractions, where they are coming one on top of the other, if you get too much too fast. Both those things have the potential to put baby in distress. The contractions can happen even if the rest of your body isn't jiving with labor (just like pitocin inductions) and that can create a dangerous situation as well.
If a mother decides to use nipple stimulation, it should be done the proper way to be a)safe and b) effective. And preferably it should be done with someone experienced there to monitor what's happening, at least over the phone.
