Any mom's on here know how well Yogi Mothers Milk tea works in aiding milk production? I've got some that I ordered a while back but I'm not a tea drinker. Does it help? If so, how many cups a day? If not, what might help aid in production that's helped you? I have one breast that is slowing down with its production and I want to keep it producing adequately so I can pump and store for my daughter for while I work. Anytime I've pumped I've managed anywhere from 3-7 ounces per side. But my one side hasn't given me more than .5 ounces each pumping, and my other side isn't pumping much either. Any help/advice is appreciated! I want to breastfeed her as long as possible!

Side note: I've breastfed for 10 1/2 months already. She snacks on normal foods and eats some normal meals as well, so she's not strictly breastfed, but she does prefer the breast more than anything still. And I want to give her my milk as long as possible.
