I did some research a few months ago on lactation when I was writing a story about hyper-lactation and here are the notes I made:
The average breast size worldwide is 650 mL.
The average milk capacity of a breast is 5 fl. oz, 148 mL, or 23% of the average breast volume. (Note that this average lactation amount is being compared to the average breast size, not to the average lactating breast size. Also, breast size does not actually correspond to milk production. But we are fetish writers. We like the breasts to make a lot of milk.)
The typical daily consumption by a baby is about 24-30 fl. oz, 708-887 mL, which is 109-136% of an average breast's volume, or 55-68% of a woman's total breast volume. This means a mother must produce about that much.
A newborn baby feeds 8-12 times a day, or every 1.5-3 hours. A two month old might feed 7-9 times a day.
Breast milk has, on average, 22 calories per fluid ounce, or 2,816 calories per gallon.
A lactating person must consume approximately 1.25 calories for each calorie expressed in milk, or 3,520 calories for each gallon expressed.
By this math, if a baby consumes 24 ounces of milk a day, that equals 528 calories, which would cost the mother 655 calories to produce. Typically, about 200 of that would come from the mother's fat stores.
Breast milk sells for $3.50 - $5 an ounce, or $448 - $640 per gallon.
