Hi Karie,
Congratulations on a valiant effort! All you need is about 1/2 oz per feeding for your little one to receive just about all the immune benefits. Have you tried
www.globaldrug.tv? They have the best domperidone prices.
Goat's rue works well for some moms. It's an herb that is very popular in California. It's purported to build breast tissue. But my opinion is that if you're going to spend the $$ on anything, you're better off spending it on the domperidone. You can cut back on the dose to save some $$ if that would help.
Fenugreek is the mother of all herbal galactogogues. And there has been some talk of an herb from overseas called Shatavari.
The most efficient way to increase your milk supply is to supplement at the breast with either the Medela SNS or Lact-aid. Some moms have brought in their milk supplies with just this alone.
Start with this and please keep me posted on your progress.
Best,
