i am really stuck on two questions on my unit please can any one help. its about understand the needs of children and young people who are vulnerable and experiencing poverty and disadvantage. the questions are

1. the importance of the practitioner as an agent of change and their role as facilitators of positive practice including the development of carers as active participants in children and young peoples lives.

and

2. the importance of multi-disciplinary working in relation to key strategic activities including the acquisition and maintenance of support services, strategic planning and interfacing with adult services
