The idea is based on studies of communities such as the Kung of Botswana, where each child is cared for by many adults.
这个想法基于对像博茨瓦纳的库恩（Kung）这样的社区的研究，在这些社区中，每个孩子都由许多成年人照顾。
Kung children as young as four will help to look after younger ones and "baby-wearing", in which infants are carried in slings, is considered the norm.
库恩的孩子们，小到四岁，都会帮忙照顾更年幼的孩子，而‘背带育儿’（即用背带携带婴儿）则被视为常态。
