Knowledge of and attitudes towards kangaroo mother care in the Eastern Subdistrict, Cape Town
Kangaroo mother care (KMC) was first initiated in Colombia due to shortages of incubators and the incidence of severe hospital infections of new-born infants during hospital stay (Feldman, 2004). Currently it is identified by UNICEF as a universally available and biologically sound method of care …

An exploration of perceptions regarding the feasibility of implementation of Kangaroo Mother Care in the maternity ward of Tsumeb district hospital, Namibia
… Dr E. Rey proposed the Kangaroo Mother Care (KMC) programme which was further developed by coworkers at one of the largest obstetric facilities in Santa Fe de Bogotá, Colombia. KMC was introduced as an alternative to the expensive and seldom used traditional methods to care for low birth …
