The purpose of this study is to determine whether the combination of Kangaroo Mother Care (KMC) as continuously as possible together with the use of a plastic bag in combination with routine World Health Organization (WHO) thermoregulation care (warm delivery rooms, immediate drying after birth, early and exclusive breastfeeding, postponement of bathing and weighing, and appropriate bundling) reduces the incidence of moderate hypothermia (32-36° C) or severe (<32.0° C) in preterm infants ≥ 32 to 36 6/7 weeks of gestational age (GA) when compared to KMC as continuously as possible together with routine WHO thermoregulation care, as practiced.
