I found it very interesting that you noted a the effect of
oxytocin on bowels.  20+ years ago at the birth of my 3rd child,
I was given too much pitocin, this was in the days with the
tablets dissolving by your gums.  I was induced for Dr
convenience.  They kept shoving those tablets in my mouth, then I
needed to push, which they yelled at me about, on 3rd push, baby
was born in the bed.  They immediatly had me spit out the
pitocin.  I had the worst diarrhea with cramping when I nursed
for almost 2 weeks after the birth.  I have always believed that
it was because of overdose of pitocin.  The diarrhea cleared up
and nursing continued fine.  Hopefully this mom can stick it
out.  It will be worth it.
Is my theory possible?  I'd be interested to know.
