When I first read the post, it reminded me of a story that Faye Young
(former P.R. director for LLLI) has told over the years and actually one
that I use when addressing Childbirth classes.  It is regarding discreet
breastfeeding and how during an LLL International Conference a reporter
was sent to get a story and pictures about the conference.  Faye relates
that she showed the reporter around the entire conference facilities and
was back where they had started and realized that the reporter had not
taken any pictures.  Faye asked if there was anything he would like
to see again to take photos of and his reply was that he wanted to go the
the room where they "did it".  Faye was confused until she understood
what he meant, and then she went on to explain that they were "doing it"
all around him.  Then the reporter began taking pictures, not of bare
breasts, but of faces--Moms and the breastfeeding babies and that
wonderful, natural relationship that exists.
Perhaps a display with pictures of Moms and babies (perhaps you could
have pictures taken of local Moms and babies).  You could always type
out some advantages of BM and display a different one beneath each
picture.
