This is a tough one.  I think it's time ILCA settled on some guidelines
for LC titles.  I would suggest:

BC (breastfeeding counselor) for a "lay" counselor such as LLL or
International Childbirth Organizations.

CBC (certified breastfeeding counselor) for grads of a recognised
breastfeeding course - in hospitals or from a school such as BSC.

LC (lactation consultant) - a grad of a recognised program of so many
hours (let's say one year course minimum) and who has passed the
examinations and requirements of that course.

IBCLC - a certified lactation consultant who has passed the Boards and
has the required amount of educational and practice hours.

I'd get rid of the other titles because they are too confusing.
What do you all think?
