With Charlie I took 4 oz (or 1 large bottle) of More Milk Plus and then quit. With Olive I've finished one small bottle of MMP (2oz), 1 bottle of Fenugreek, 1 bottle of Blessed Thistle, and 2 boxes of Mother's Milk Tea. I stopped taking supplements because I got mastitis and didn't want to be making more milk!
But now that I'm over it and my milk supply has taken a hit, I'm going to start taking supplements again. I'll stop once I achieve my a good milk supply level, but I'm wondering... how long did you take supplements? Until you increased your supply to a good place? The entire time you breastfed/pumped?
