Wet-Nursing and Cross-Nursing

on November 16, 2015

If you have ever cared for someone else’s hungry breastfed baby, the thought that things would be easier if only you could nurse the baby has probably crossed your mind.  If you are lactating at the time, you may have seriously debated the ethics of latching the baby on to your breast.  Complete/full time nursing of another’s infant, often for pay, is called wet-nursing.  Cross-nursing is the occasional nursing of an infant whose own mother continues to breastfeed him/her on a regular basis.

Most situations in which cross-nursing is practiced are private arrangements made between the mothers involved.  Day care and babysitting seem to be the most common situations in which it is used.  Cross-nursing or wet-nursing has also been used when hospitalization of a nursing mother is necessary.  This is especially true in an emergency when the mother is unable to nurse or the potential effects on the infant of the mother’s prescribed medication dictate temporary weaning.  As it is rarely talked about, there is no clear data about how many breastfeeding mothers cross-nurse occasionally or regularly.

La Leche League (LLL) fully supports the use of human milk for babies.  The first priority of LLL is to help mothers breastfeed their babies.  A second priority is helping mothers to express and safely store their own milk for their babies.  When their own mothers’ milk is unavailable, babies may need human milk donated by other mothers.  It is essential that this donated milk be safe.

As an international organization, La Leche League International (LLLI) is aware that many mothers in many cultures have informally shared their breastmilk and wet-nursed among family members and trusted friends.  LLLI also recognizes that in times of severe maternal illness or death and natural disasters, sharing milk has been lifesaving for infants.  When a mother contacts a Leader seeking information about using donated human milk, a Leader may suggest the mother also dialogue with an appropriate, licensed health care provider and contact a licensed human milk bank or other regulated and medically supervised human milk collection center. There are currently four human milk banks in Canada operating in Calgary, Montreal, Toronto, and Vancouver plus the Human Milk Banking Association of North America.  The Canadian milk banks abide by strict operating procedures, which include donor screening, medical supervision, bacteriological testing, pasteurization, storage, and distribution.  Due to limited supply, the donated human milk available from the milk banks in Canada is only available by prescription to babies who meet strict criteria.  Protocols for the careful and safe collection and handling of human milk are the responsibility of milk banks and networks.  Mothers are encouraged to evaluate these protocols carefully, in order to make an informed decision.

La Leche League does not suggest or recommend specific informal milk-donation/sharing arrangements.  La Leche League’s role is to provide support and information if a mother asks about informal milk sharing so that the mother can make her own informed decision based on her situation.

The benefits of donor human milk include, but are not limited to:  optimal nutrition, easy digestibility, and immunologic protection.

Risks of unregulated donor human milk can include transmission of bacteria or viruses.  These have been found in milk expressed by women who are showing no signs of illness.  Prescription and non-prescription drugs and environmental contaminants can be present in breastmilk.  There is potential for unhygienic handling and improper storage of unprocessed donated milk.  In a study of donor breastmilk purchased from ads found on the internet, some samples were found to have been extended with cow’s milk to increase the volume.

The mother who is cross-nursing may experience a reduced supply of milk for her own baby.  Various factors, including the ages of the two babies and the regularity of the cross nursing schedule, would affect whether or not the cross-nursing mother’s milk supply would build up to meet the needs of both babies.

Babies of different ages require a specific composition of milk.  Milk from the baby’s own mother will provide the exact make-up the infant needs; another mother whose baby is not the same age may not provide the same components in the same ratios.

Cross-nursing can also affect the baby psychologically.  A difference in the let-down, either in the timing or in the forcefulness, may confuse or frustrate an infant.  Women have reported that babies four months or older often refuse to nurse from another mother and will chose to wait until their own mother returns. Babies of this age also often refuse to take a bottle as a substitute for breastfeeding with their own mother.

Nursing mothers who donate to milk banks are screened carefully using the following criteria:

  • they should be healthy, well-nourished and taking no medication.
  • they should be screened for tuberculosis, syphilis, hepatitis-associated antigen, cytomegalovirus, herpes virus, HIV and other infectious agents.
  • they should not smoke, drink alcohol, or consume large amounts of caffeinated or artificially-sweetened beverages.
  • their own infants should be healthy, gaining well and free of all infections.

La Leche League Leaders are happy to help mothers in any situation, work out their best options for providing their breastmilk for their babies.
