The domestic mother-infant sharing room model began in the late 1980s and early 1990s. The mode of mother-infant sharing room in China can be traced back to the late 1980s and early 1990s. This model stems from the attention and concern for the early parent-child relationship of newborns, aiming at promoting the emotional connection and interdependence between mother and baby. Sharing a room means that the mother and newborn live together in a hospital or postpartum nursing institution and share a room, so that the mother and newborn can keep close contact and intimate relationship and spend the early period of the newborn together.
