Re: 3rd LC and nothing works :/
Mama, you have been such a trooper through all of this!
When a baby adjusts his latch partway through a feeding, it can be because he's trying to control a milk flow that is too fast or too abundant. My LC said it was like crimping a hose to slow the flow of water. If this is the problem, changing your nursing position and controlling any oversupply issues should help. Another reason a baby may lose his latch over the course of a feeding is because the breast is heavy and the baby is tiny: imagine if you had to hold up a water balloon that was bigger than your head using just lips, gums, and tongue! Eventually you'd probably lose your grip on the thing. If this is the problem, supporting the breast and baby throughout the feeding, using hands, pillows, and maybe a rolled-up washcloth tucked underneath the breast, may help.
If you are so sore that nursing has become unendurable, you can feed from just one breast or predominantly one breast. That avenue has some drawbacks. You'll need to slowly transition from feeding on two sides to feeding on just one, because your "good" breast probably doesn't have a supply that's adequate for baby all by itself, at least right now while it's sharing the workload with your "bad" breast. Also, if you don't allow the supply in the "bad" breast to decrease slowly by gradually reducing what you demand from it, you could end up painfully engorged or with mastitis again. If you wean from the "bad" breast, and don't maintain supply on that side by pumping, you may not have much of a back-up milk supply in that breast for an emergency situation in which your "good" breast is out of commission.
I understand why the LC told you not to start on the "good" side every time- doing so could increase the supply on that side and decrease supply on the other to the point where you become lopsided. Which might be an acceptable trade-off for you!
Just keep hanging in there, mama. I know you are in real pain and it's not easy to continue, but I am sure that if you give this time you will eventually be able to use both breasts without pain. I was- it just took a long time, much longer than that magical 6 weeks everyone talks about!
