J.S.
N.,
I sympathize with you. I had mastitis, blocked ducts, one breast much larger than the other, etc. I used two different lactation consultants, both very helpful. Try www.naturalbeginningsonline.com. Sharon Matties and Linda Worzer might be able to help. La Leche League was not helpful to me and I would not recommend them as a first course of action. They told me to taper off feedings on the larger side and this actually caused my mastitis. Give thanks for the breast that produces more and use it until things balance out better. My daughter nursed until 2 1/2 and my left NEVER made as much as the right.
Also, review your diet. Your body needs LOTS of nutrition and WATER in order to make enough milk. The stress you are under is a challenge to milk production as well. I applaud your efforts, as breastmilk is best for baby. Fenugreek is a common recommendation for increasing supply. Practice envisioning you both nursing comfortably, easily, satisfactorily. Do this every day, even when you feel your current reality does not match that image. Try to love yourself as much as you love your baby. You're a great mom.
Good luck.
