Their is Milk dust supplement for nursing mothers that are capable of nursing, it is manufactured in the USA and sold on Amazon with next day delivery available from many different companies.
baby formulas seem simple, certain colostrum proteins is what makes one better than the other, why its not easy for USA manufacturers to be supported is just wrong, many overseas produced baby formulas have been found to be contaminated with undesirables (Heavy Metals), companies in the USA that desire to produce are having to deal with red tape. even a certain manufacturer who received an award for cleanest manufacturing warehouse cant produce this at the moment. we live in an age were government involvement in all matters increases the suffering of the innocent the destruction of American capability, and failure to most simple solutions before they can even get started.
