The kangaroo mother care (KMC) method is a “45-year-old innovation” in health care to care for premature or low birth weight (LBW) infants: the KMC position with direct skin-to-skin contact on the chest of the mother, KMC nutrition based on breast milk and early home discharge in KMC position with close monitoring are the three key elements of this intervention. Created in 1978 to compensate for the lack of incubators in a huge maternity hospital in Colombia, it has always met with resistance from health professionals. Rigorously studied, it has shown benefits far beyond the reduction in mortality, to ensure a proper quality of life for these fragile babies. KMC has become an example of evidence-based care for premature or LBW infants, and it is no longer ethical not to apply it. Exploratory analysis results on brain growth according to the duration in days of KMC position are presented in this article and should help accelerate the systematic introduction of KMC as early as possible and for as long as possible from birth, as published by the WHO in 2022.
