Multiple caretaking arrangements exist in non-western societies with other members of the household and the community assisting the mother in child care. These others include the children's older siblings especially in subsistence based horticultural and or pastoral societies where sibling caretaking comprises a large portion of children's daily activities. During these caretaking sessions, older siblings may intentionally or unintentionally transmit culture to the younger children. Caretaking of small children thus implies transmitting cultural values to the children in everyday context during everyday activities. As very little research has been conducted in the area of sibling teaching, this study sets out to investigate sibling teaching among the Agikuyu of Kenya by means of video recording. It looks at the different teaching abilities and strategies of the children according to age and social status. It also pays attention to the cultural context, in which the teaching occurs, as well as to the reflection of social relationships found in the children's interaction. The author points out, that and in what way children can be important socialization tools to their younger siblings.
