It is also thought that originally there wasn't enough money for the children of farmers to buy toys so the mothers made the dolls as a toy for their children to play with.
They are also given to daughters as good luck charms for a good marriage, easy delivery and healthy children, and a happy home.
They have no faces so the owner can imagine it and the "Sarubobo" can reflect the owner's feelings. When the owner is sad the doll is sad - when the owner is happy the doll is happy. The doll can sympathize with the owners feelings.
