Must be a step son thing!!! I have a 10 year Step son and he was really acting out when he was at his mums and came to live with us... he seems to be doing well at school, but he just doesn't seem to be able to stop lieing.... i am at my wits end to and wish i could offer some helpful advice!!! I need some myself!!! He acts up even worse when he goes to his mums! I just can't deal with the lies and taking without asking and then lieing about it!!! you have my deepest sympathies!
