I have a 12 yr old son who has been diagnosed with mild ADHD. He takes ritalin which definitely helps. My problem is that lately he has been caught lying and cheating at school. Even when he's caught red handed he denies he did it or he blames it on another student. My wife and I have taken away just about every privilege he's got but to no avail. We make him write papers about thinking errors. He also tends to lie through omission. He sees a therapist. I feel we are running out of options. I'm worried that we may be damaging him emotionally. Does anybody have any suggestions? Thanks.
