Hi J.---Congrats on expecting more babies. Be sure to remember to have lots of fun. They grow up way too fast.
You've received lots of great advice. I haven't had experience with donated breast milk, but I know that wet nurses have been used for centuries.
My suggestion comes from my experience as a Wellness Educator. To make sure your body is able to make as much milk as it is capable of making, be sure to pay close attention to your diet. The benefits of this will ensure that your babies are as healthy as possible as well and that you make as much breast milk as your babies demand.
I am taking a series of classes offered by a Naturopath who has her PhD in Nutrition. Long term research shows that the best diet for humans consists primarily of fruits, veggies, whole grains, legumes, seeds and nuts. Use animal protein sparingly, like a condiment or a seasoning for soups and stews. This includes cows milk. Cows milk proteins tend to be cause for allergies and problems in the human body. I urge you to visit www.strongbones.org and www.pcrm.org to learn more if you are interested.
During pregnancy and lactation, you will need extra calories but the ratio of carbs, fats and proteins should always remain consistent. You will get plenty of protein and calcium from plant based sources, when you eat enough of them. Lots of plant based foods also help to attain and maintain optimal weight.
I also recommend a great whole food supplement, made from the dehydrated juice powders of 17 differenet fruits and veggies, that will make every cell in your body stronger and work better. We have great research showing healthy pregancies with no pre-enclampsia, no low birth weight babies, no NICU (probably single births, mostly) pre-term, etc. As you are pregnant with triplets, you are most likely considered high-risk, and your body produces a much larger amount of free radicals as a result. Your diet must be better than good to reduce your risk for complications and to neutralize those free radicals.
If you are interested in any additional information on the thoughts that I have shared with you, feel free to contact me at any time. It is my passion and great honor to help other families achieve optimal health. I look forward to your call.
In health, and good luck :) D. ###-###-####
