Abstract
The purpose of this research is to investigate changes over time of a child with severe disabilities and her mother as social beings from the perspective of co-occupation. Researchers conducted interviews of the mother and had participant observations of the mother and child. The mother and child’s occupations have changed along with the child’s development and her occupational place expanded beyond mother and child, to family, and society. Contrary to the traditional model of mother and child that features only that relationship, the mother and child studied had included others so that the child’s social participation was facilitated. The study investigates how the child has developed as a social being and how the mother coached her social participation with the perspective of co-occupation.
