Care is needed at all stages of life. This unit makes care in the family its focus because the overwhelming majority of care, including health care, is supplied in families, much of it in private, much of it unnoticed and unremarked upon. The meaning of the term (informal carer) and the word (care) itself are explored. This study unit is just one of many that can be found on LearningSpace, part of OpenLearn, a collection of open educational resources from The Open University.
