Akua ba are wooden fertility figures from Ghana and nearby areas in West Africa. The best known examples are those of the Asante people, whose akua ba have large, disc-like heads. Traditionally, women carry these figures on their backs to ensure the conception of a child and to ensure the beauty of a child being carried. Web resource here.
