Final answer:
During a play therapy session, a counselor should explore and engage with metaphors used by a child to better understand and support the child's emotional expression.
Step-by-step explanation:
When a child is using a metaphor in a play therapy session, the counselor should recognize the metaphor as a valuable tool of expression. Metaphors can provide insights into a child's thoughts and feelings that may be difficult for them to express directly. It is important for the counselor to explore the metaphor with the child, helping them to articulate and understand their emotions and perspectives. This engagement shows attentiveness to the child's inner world, facilitating a supportive therapeutic environment. It is vital to listen actively, validate the child's expression, and possibly even expand upon the metaphor as a therapeutic technique to delve deeper into the child's experiences.
