Play therapy is a form of psychotherapy that uses play to communicate with and support children, to prevent or resolve historical and/or present challenges. It can aid them and their families towards better social integration, growth and development, emotional balance, and trauma resolution. A play therapist observes a client playing with toys (play-houses, pets, dolls, etc.) to determine the cause of the disturbed behavior. The objects and patterns of play, as well as the willingness to interact with the therapist, can be used to understand the underlying causation for behaviour both inside and outside of therapy session. Play therapy can be used as a self-help mechanism to encourage the client to manage their challenges and support themselves more effectively.
