As long as there’s an adequate supply of donor milk, you can feed your baby for as long as you like. That is, of course, if you can afford it. “Most milk banks charge between $4 and $4.50 an ounce,” says Bar-Yam. “That’s about $1,000 to $1,200 a week.” Most banks will work on a sliding scale for families who can’t afford that price, and you may be able to get your insurance company or Medicaid to cover all or part of the cost, Bar-Yam adds.
If you need donor milk, be sure to contact an HMBANA bank (hmbana.org). “Black market” breast milk can actually be bought on the Internet— but stay away from it. “You don’t know who you’re buying milk from, and you have no idea whether this person has been tested for communicable infections,” cautions Liz Maseth, R.N., IBCLC, director of outpatient lactation services at Akron Children’s Hospital in Ohio. “And who’s to know whether it’s even human milk?”
One final word: Milk banks have a limited supply and exist only for babies who truly need breast milk. “They are not designed for moms who don’t feel like nursing,” Bar-Yam says.
While on a 2009 humanitarian tour of Sierra Leone in West Africa, actress Salma Hayek caused a media stir when she breastfed a hungry infant. “Cross-nursing, as this practice is called, is the occasional nursing of another mother’s infant,” Maseth explains.
Cross-nursing is usually practiced between sisters and very close friends and for the same reasons as using donor milk. “It’s generally done in tight social circles because you’re more likely to be familiar with the health behaviors, such as drinking or smoking, of people you know well,” says Michelle Collins, M.S.N., C.N.M., R.N.C., assistant professor of nursing at Vanderbilt University School of Nursing in Nashville, Tenn.
A variation on cross-nursing is milk-sharing, in which lactating women freeze extra milk to give to a relative or friend whose baby needs it. Julie Lifferth, 28, of Smyrna, Tenn., receives milk from her two sisters-in-law because her son was born with a cleft lip and palate. “Parker was unable to latch properly, and I struggled with my supply,” she says. Because she milk-shares with relatives, Lifferth has no qualms about feeding Parker other mothers’ milk. “They’re both healthy, and neither of them drinks, smokes or uses addictive substances,” she says. “Milk-sharing is awesome, but I wouldn’t be comfortable taking milk from someone I don’t know.”
Experts agree. “Breast milk is a body fluid,” says Rothenberg. “You should use at least the same standards that you would for accepting a blood transfusion.” In addition to asking about any medications she’s taking, inquire whether the donor has been blood-tested for infectious conditions, as HIV and other diseases can be transmitted through breast milk.
