Valid question as the need for self-sustainability runs higher now than it ever has in our lifetimes. Solar panels and internal water filtration systems are not enough these days, as the need for one to provide one's own food may soon be a literal necessity. Personally, at my world-famous Miami Steve's Wisconsin-Style Pizzeria we do not use human-lactated milk for our cheeses that are made in-store to guarantee the best slice you've ever had since your umbilical cord got cut.
That out of the way, how much breast milk do you produce weekly?
P.S.- Lamb Horse, you stay out of Miami Steve's Chicago Chimneys. Out!
