Kangaroo care

Kangaroo care, or skin-to-skin care, is a technique practiced on newborn, usually preterm, infants wherein the infant is held, skin-to-skin, with an adult. Kangaroo care for pre-term infants may be restricted to a few hours per day, but if they are medically stable that time may be extended. Some parents may keep their babies in-arms for many hours per day.

Kangaroo care, named for the similarity to how certain marsupials carry their young, was initially developed to care for preterm infants in areas where incubators are either unavailable or unreliable.
