Breast Feeding - Shared Breastfeeding

It is sometimes common for more than one woman to feed a child, such as in developing nations within Africa. This shared breastfeeding has been highlighted as a source of HIV infection in infants. A woman who is engaged to breastfeed another's baby is known as a wet nurse. Islam has codified the relationship between this woman and the infants she nurses, and also between the infants when they grow up, so that milk siblings are considered as blood siblings and cannot marry.
