One technique she proposed was called "kitchen table therapy." In kitchen table therapy, Fraiberg would go into the homes of parents with young children, typically under the age of two. There are three different approaches to kitchen table therapy. They are brief crisis intervention, developmental guidance-support treatment, and infant-parent psychotherapy. Each type of therapy is used for different situations, depending on where Fraiberg or her colleagues thought the problems in the parent/child development relationship were stemming from. Brief crisis intervention was used when there was few, specific, situational events that resulted in a lack of helping the child develop. Developmental guidance-support treatment is used in situations where the baby may have a chronic illness or disorder and the parents are struggling to find a way to move beyond that problem. This therapy technique is used when parents are still capable of being good parents, but simply need assistance in how to practice that. Infant-parent psychotherapy is used when the parents have their own struggles from their past which prevent them from developing an attachment with their child. The main goal of this technique is to rid the parents of their problem so it does not transfer onto the child. The purpose of these three types of therapy is to prevent development and attachment delays in children. These therapy techniques combine psychoanalysis, psychiatry, and social work practices to help parents and children establish foundations for development and attachment in the child's first few years of life. Fraiberg developed a new technique to approach infant and parent treatment. This approach for developing infant relationships with their parents until the age of two brought the treatment into the home and is still used today. Her practice was the start of infant mental health development and is still being used today, only with small adjustments and modifications to account for changing urban and rural lifestyles. Fraiberg's new approach to infant mental health was different than current approaches of her time. However, they continue to be the building blocks of infant mental health today. Fraiberg's concept of "ghosts" in her infant mental health studies is still prominent in infant theories and studies today. In her paper "Ghosts in the Nursery," Fraiberg said problems in infant development and attachment stem from the ghosts of their parents. The unremembered ghosts prevent parents from fully developing a deep attachment with their child that is important to their development. This concept of ghosts is used as a function of psychotherapy. The function is helping the subject leave their ghosts behind and continue moving forward with their life.
