Working with children is challenging in many ways, not least of all ethically. When health professionals work with children or young people they are, to a greater or lesser extent, also working with at least one parent or guardian. A child rarely presents for therapy without an adult deciding it is necessary for some reason (Koocher, 2008). Sometimes it is a parent or a teacher who wants the child to attend therapy, and sometimes it is a family therapist (Lowe, 2004). Given that young children are not always in a position to give informed consent to treatment such as counselling or psychotherapy, the adults involved are required to act in such a way as to protect the 'best interests of the child'.
