My step-sister is from the USA and she was shocked to hear that we don't have milk banks here. When she BF'd, she had enough milk to feed the 5000 so she mentioned donating to milk banks. When I told her that they don't exist here she thought that was really strange.
I am not sure I would want Gabby having milk from someone else but that's because I can feed myself. If I wasn't able to, it might be a different story. Very interesting.
