Mary, the first thing I thought about in response to your question is the
development of oxytocin receptor sites when the uterus is readying itself
for birth. When those receptor sites aren't ready, the uterus stays pretty
quiet even if there's oxytocin or Pitocin circulating in your system.

In this situation, however, her body seems to be getting ready to give
birth early.
So her uterus is reacting as if it's getting close to term.....(We see this
in labor and delivery -- even if a mom is 41 weeks, if her receptor sites
aren't ready no amount of Pitocin will successfully put her into labor.....)

There's actually a nice little article about this at
http://kellymom.com/pregnancy/bf-preg/bfpregnancy_safety/

I nursed through two (normal) pregnancies and know what a wonderful
mothering tool the nursing is. I wish her well and you too as you share
this info! She may need help from someone who understands how much the
toddler loves to nurse and how hard it is for mom and Little Nursing Person
to give it up for now!
