Lyndon is an 8-year-old boy who wants to have everything now! He seems unable to wait for anything

For example, although his parents have encouraged him to save a small portion of his weekly allowance, Lyndon invariably spends all of it, usually on the day that he receives it. How might his parents encourage Lyndon to exercise self-control and delay gratification?
What will be an ideal response?

A good answer will be similar to the following:
First, Lyndon's parents might want to examine their own behavior. Are they overly strict and controlling with Lyndon or do they establish well-defined limits on what behavior is acceptable in a warm and loving way? Children of parents who are very strict and controlling do not internalize self-control, while children of nurturing parents who set clear guidelines for behavior show greater self-control. Second, do Lyndon's parents engage in monologues in which they simply assert their power? If so, they should change their behavior and engage in dialogues filled with suggestions and negotiations. Third, during the waiting period while Lyndon is delaying gratification, they can help Lyndon wait by providing distractions and by helping him find ways not to think about the things that he wants to buy.
