London, Dec 5 (IANS): A cash-strapped mother-of-four in Britain has revealed that she is selling her breast milk and plans to fund Christmas expenses with it, media reported.

Rebecca Hudson, 26, from Manchester, Thursday revealed that she has so far made 3,700 pounds (about $5,700) by selling breast milk.

The mother came up with the idea after she realised that she was producing more milk than her youngest child Milly, now one-year-old, needed, the Daily Mail reported.

She sells the milk for 12.50 pounds a bottle and has amassed a devoted group of eight clients.

Hudson also admitted that some clients purchase the milk to use for "sexual purposes".

"What they do with the milk is up to them," she was quoted as saying.

"I'm not going to discriminate. There's no difference for anyone who wants to use the milk, from a bodybuilder to someone who wants to use it sexually."

She also used her appearance on an ITV flagship show to hit out at those who say drinking breast milk is revolting. She argued that drinking the substance is completely "natural".

"Some think drinking breast milk is disgusting," Hudson explained. "That's their problem. It's natural and full of vitamins."

Hudson is not the first person to make money from breast milk. Mommy Milk Creations was set up by mother-of-three Allicia Mogavero earlier this year and uses the substance to make jewellery.
