The increase in recent years of the new family formats has also meant an increase in the demand for breast milk for babies who are breastfeeding. In Catalonia breast milk can be given through the points enabled by the Bank of Blood, and since last October there is an app called LactApp that solves all the doubts of parents who want milk from another woman to give it to his sons and daughters.
At the same time, in the United States, breast milk is bought and sold through a social network called BBY. The people who install this app can sell or buy breast milk. To guarantee all sanitary controls, the donation is always done in a hospital or clinic.
