Hang in there! I admire you for sticking with it!
I started out making very little milk. About 0.5 oz per feed or less. I knew this not because of pumping, but because I did weigh/feed/weighs at a BFing clinic. I tried absolutely everything except standing on my head. Fenugreek, pumping, drinking tons of water, oatmeal, beer, mother's milk tea, etc. Nothing worked! I was so stubborn, I didn't want to have to take medication. I thought I could do it on my own. At about 7 weeks I had a uterine infection and was checked for retained placenta. After that was ruled out, I guess you can say I was ready to give it one last shot. I went on Domperidone at 7 weeks PP. It didn't happen instantly, but very gradually with lots of pumping. Also, I was putting my son to the breast practically every hour. It was an uphill battle, heartbreaking at times and joyous at others. It's a struggle unlike any I've ever faced. But it's the most amazing feeling to know that whatever happens, you got one more day of breastmilk into your child. I was told in the beginning I'd probably never make more than 0.5-1 oz per feed, and that I'd probably have to supplement a majority of his calories. Well, they were wrong. While he's never been exclusively BFed, at about 3 months old, I was making about 75% of his calories. Now, at 8.5 months old, he gets one bottle a day before bed (about 4 oz) I would have continued to nurse even if I only had a drop, but it is such a blessing to me that I'm able to make almost enough for him now.
It is so rewarding. Really. It is. Breastfeeding is about SO MUCH MORE than just nutrition. It seems so hard now, and it is, but as each day passes and you get more time under your belt, you may find it becomes less about the actual milk and more about the bond between you and your child.
