This raises his self-esteem and allows him to envision himself as an active and valuable participant in other group activities, now and in the future. In other words, though your son may receive allowance which is part of his privilege, it should not be assumed that he can decide to forego his chores and turn down his allowance. Your authority includes setting realistic expectations for him to fulfill. The allowance represents the respect and value of his contribution to the family. Solicit suggestions from your son about what chores he would like to take on, and be open to negotiation when special needs arise.
Exceptions are fine as long as the chores are reinstated as soon as possible.
As your son matures, family duties may be matched with increased responsibility. Driving privileges can carry responsibility for weekly grocery shopping or some other duty which involves driving the car. This pairing of responsibility with privilege creates a sense of fairness and gradually prepares you son for the reality of adult life. You are preparing your son to be a valuable member of the society in which he lives when you encourage his active participation in family upkeep. You should not rely on this information as a substitute for personal medical attention, diagnosis or hands-on treatment.
