No matter what the behavior looks like in a child, parents will usually become concerned and want to seek help for their child. One of the best ways to help children with behavioral and emotional problems is through an approach known as play therapy. Play therapy is a psychotherapeutic treatment approach specifically developed to help children between the ages of three to 12 years old. A trained mental health professional, called a play therapist, works with a child to explore and resolve problems through the therapeutic use of play.
