Internationally Board Certified Lactation Consultant
It's been my experience that not ALL IBCLC's are listed on the ILCA website, though it is a good jumping off point. You should also be able to locate one by calling the OB dept of your local hospital(s), or even calling La Leche League. Some Leaders are also IBCLCs. I would suggest an IBCLC in your particular case just because it's a little out of LLL scope.
