I agree that your best bet is to offer the workshop in combination with a
regularly scheduled Grand Rounds that attracts physicians.  If you have a
breastfeeding friendly "opinion leader" , e.g a chairman of a Dept. who would
be involved that would also help.  Certainly offer CMEs to the docs--they must
have a certain amount each year and would be most likely to attend something
with no charge that offers them.
