You are doing the correct thing by having your son see a therapist. It is no wonder some of this behavior is occurring, in light of the broader context and the irresponsible behavior of his father. Part of the clinician's intervention might be some contact with your son's father to see if he can see the errors of his ways and begin to act in a more responsible fashion as a parent. If that situation does not change, it is going to continue to pose problems for your son and make it very difficult for him to do better. While it is too early to know, if your son's father cannot act more appropriately and responsibly, it might be necessary to curtail any unsupervised contact betwee them.
