Yes, my 10 year old stepson also has ODD. I have found that when his tantrums get out of control, being also that he is older and much bigger now...as cruel as it may seem, I sit on him. This is not only to protect me from swinging arms and legs, but to protect himself. I hold him down and just keep repeating that he needs to calm down, and that I will get up when he is done and calm. Eventually he quits fighting, breathes hard for a little bit, and then everything is over. With ODD, they try to defy every bit of discipline you enforce...even to their own detriment. They are their own worst enemy and don't realize it. If you send him to his room, and he doesn't go..just tell him ok. Have everyone else in the room leave him. Later, when it is calm enough, he needs to apologize and make ammends to everyone who had to go out of their way, or drop what they were doing because he wouldn't listen. This can work for all punishments imposed. Best advise...try what you can to get it under control now...they only get bigger, stronger, and more determined. We have also resorted to phsychiatric counseling as well. Many of the medications out there don't do much to help, unless you are using all the tools available. And we've found, that counseling is the best tool of all, and meds haven't been needed.
