First of all, it is important to note that Love and Logical does not work with these kids. While it is a good program and FLO teaches L&L, it is based on cause and effect. That does not work with AD.
Children with AD need to see a behaviorist that has a solid background, training and practical experience. Unfortunately these kids only learn to maneuver and distort most of the therapeutic models in an individually focused, therapeutic settings. Specially the emotionally focused models only teach the children how to answer so that the parents would get into trouble in the eyes of the therapist.
The client isn't the child; it is the family. The whole family needs psychoeducation and practical tools to be able to live with the particular case of AD their child presents. This approach provides the family with the tools and support they need to support the child. Practical tools and knowledge what they are dealing with are the primary needs here, the analysis of the cause is secondary at this time.
In terms of behavior issues, it does not matter that the child was in foster care, is adopted, or has a severe trauma history. When this child is an adult and still has a tantrum like a three year old toddler, it is not "cute" anymore. One core fear the parent's often have is what will happen to their children when they grow up and they have not managed to learn to control their behavior. The general society is not interested in why Simon or Suzie cannot control their out bursts. This is why these parents need that extra support and education; they cannot guide their kids forever.
