Interaction with the parents forms a crucial part of therapy. The therapist usually talks to the parents prior to the first session with the child, because it is important to understand the context in which the behaviour of the child has developed. It is also necessary to know what the parent's communication and discipline patterns with the child and the nature of boundaries are. The therapist then works with the child alone, but she will contact the parents should important issues arise. Regular feedback sessions are usually scheduled at the parents request. The therapist and parents will work together to understand the child and to develop constructive, respectful and supportive ways of communication with the child.
