    Parenting tips obtained from hunter-gatherers in Africa may be the key to bringing up more contented children，researchers have suggested.The idea is based on studies of communities such as the Kung of Botswana，where each child is cared for by many adults.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 common practice.
