I am at my wits end.I have three ds 12, 10, 6. The oldest has a sporadic relationship with the truth. Its his go to to lie instead of telling the truth, it ranges from the silly to important things.Even when caught he tries to elaborate to get out of the situation . We have tried talking to him, this has been an issue from a very early age, so we have gone from the boy that tried wolf to now trying to instill in him the need for trust, that I need to know he is telling the truth. At the time he seems to understand but he quickly reverts.
