Kangaroo care (KC) of preterm and high-risk infants was first described by Drs. Rey and Martinez in Bogata, Columbia in 1983. It has been implemented in neonatal intensive care units throughout the world. KC could maintain physiological parameters, such as: reducing apnea, stabilized heart rate and saturation, increasing quiet sleeping time and gaining weight. Furthermore, it could decrease parents' stress and anxiety, promoting attachment between parents and their infants. Thus, we should try to spread the practice for preterm infants and their parents. Many investigators deliberated researcher about KC. The writer will organize and present the literature review, including the concept, the benefits, and the matter needed. We wish that all the preterm infants could deserve cares in a humane way .
