Hi J.----I'm not sure, but it seemed to me that pumping never produces as much milk as your baby actually nursing. Of course, there is no way to know, but that's how it felt to me.
Another way to make sure your body is working the best that it can is to pay special attention to your diet as a whole. No supplement or single herb/nutrient can make up for the totality of the diet. Be sure your diet consists primarily of fresh fruits and veggies, whole grains, legumes (beans), nuts and seeds. Minimize animal protein, and that includes cows milk, as well as negative ingredients such as chemical additives (artificial colors, flavors, preservatives, MSG), HFCS (highly processed so it's not real food), simple carbohydrates (anything white).
These guidelines come from a Naturopath that I work with. She has her PhD in Nutrition and bases her work on long-term research. Please read The China Study by T Colin Campbell and explore www.pcrm.org. Drs. Bill and Jim (ABC The Doctors) may also have some useful advice for you at www.askDrSears.com. I have the honor of working with both of them as well.
When you optimize your nutrition, every cell in your body works better. Please understand that I am not suggesting your diet is bad, but rather, because you are demanding more from your body, your body demands more from your diet. Besides, eating this optimal diet will reduce your risk of degenerative diseases as you age.
I am amazed at what I am learning and what is NOT being taught by the professional that are supposed to keep us healthy. Medicine today is very good at fixing things. I'd like to see us get to the point where prevention is the norm and we only have to use doctors in emergencies.
Sorry about getting on my soapbox, but this is really important. If you would like to learn more, I would be honored to answer your questions. Good luck. Have fun with that baby. In health, D.
