We went on to have two more kids because the first thrived on formula and we were able to otherwise provide a healthy and nurturing environment for them despite not being able to afford banked milk.
I don't mean this to be rude, but given your stance I don't really mind if it is... how many kids do you have?
How do milk banks cope with
shortages? (Note how their front page mentions their "acute" shortages.) How do poor people going to pay for banked milk (it's more expensive than formula.) How many of those breast milk banks are in the developing world?
Breast milk is unquestionably better than formula and there are noted disadvantages to formula, but repeating "MILK BANKS!" cures the problem of getting breast milk to every infant about as well as Republicans repeating "CHARITIES!" cures poverty.
