People may donate/sell their sperm or blood but it doesn't seem right for me to sell breastmilk. I can donate for the real needy babies but selling? I think it is only if you have more than enough supply of it. I don't know but my idea of selling is when there is enough supply to cater to the demands of the consumers. When I have breastmilk, I reserve it for the needs of my own baby and sharing it (to be sold) to others would mean depriving my baby of the milk that she/he may need anytime.
