Play therapy
Nondirective play therapy is based on respect for the child and confidence in his or her ability to direct his or her own process. It requires that the therapist maintain unconditional acceptance and positive regard for the child. Because children do not typically have the cognitive and language skills to communicate their emotional experiences, by observing a child’s play sequences and play themes, the therapist can gain great insight into the child’s inner world. By creating a safe, free, and protected space, the child is provided the opportunity to work through deeper emotional fears, wounds, and experiences. Children are given permission to express themselves in whatever way they are comfortable and are not required to speak, which often feels intimidating and scary to a child.
