I need some advice from those of you that have experience with older adopted child behaviors. For the past few weeks, Blake has been increasingly disrespectful of his parents, teachers, and classmates. He is mouthing back every time he is told no or corrected. He is very close to yelling when he does this. We are hearing things like "it's not your business", "you are mean", "why don't you like me", "Blake was the boss at the orphanage", "shut up", etc. etc. He recently added a long loud disgruntled huff and eye rolling. He is developed quite the attitude!
We have been taking away privileges, like playing outside, following a warning. It doesn't seem to be getting much better. We now feel we need to forego the warning and be extremely consistent on giving an immediate consequence (loss of privilege) for his behavior. We think that if we are consistent, he will eventually realize that his behavior is unacceptable.
Any suggestions or insight would be appreciated. Thanks!
