express or pump en group!

 From New Scientist:
Two years ago, Martha McClintock of the University of Chicago showed
that women who live at close quarters really do tend to synchronise
their menstrual cycles, backing the popular perception with hard
evidence (New Scientist, 14 March 1998, p 6). Now her team has found
that lactating mothers can also influence other women.
The researchers asked 26 breastfeeding women to wear absorbent pads
in their armpits and inside their nursing bras. Then they asked 54
female volunteers to rub these pads under their noses four times a
day for about two months. After the volunteers' first menstrual
cycle, half the women got pads collected from the nursing mothers.
All the women had regular cycles before the experiment began. But the
researchers found that among the women who sampled "eau de breast",
short cycles became significantly shorter and long cycles became
significantly longer. "Some kind of chemosignal from the
breastfeeding environment is disrupting their cycles," says Natasha
Spencer, a member of the team.
McClintock's team now wants to find out if the timing of pregnancies
of groups of women can be synchronised by a chemical signal.
