The woman is 29 years old and says "I am a young mother in perfect health, a trained nurse of 29, and I am renting my breasts to milk-feed infants.”
Her price is a hefty $130 per day.
The offer is being made to gay couples in France who adopt children and want the babies to be breast fed. That country recently made gay marriage legal.
The ad is seen as a way around laws that make selling breast milk illegal in France.
The CEO of the company that came up with the idea claims their attorney says “this is a person proposing a service, not selling the milk in flasks.”
The idea is catching on with the initial advertiser "I've received more than a dozen requests," she said.
However she was quick to point out "only half of them were serious, the rest were from perverts."
