I am feeling a litte gulity here and need some reassurance.
My son continually slams his door when he is sent to his room for a time out. Then once there he lays on the floor and kicks the __it out of the door. We recently built a new home so I don't want him damaging the door. In addition, my dh, works third shift and is sleeping during the day so I don't want the noise of the door slaming.
This weekend I got so frustrated that I took the door off. IMHO, if he needs privacy he can go into the bathroom. As for now the door is gone. He continually asks when he will get his door back. With his behavior I am not sure he ever will.
Am I a bad mom for taking his door away?
no you are not a bad mom for taking his door away. I also had to do this when my son 4 four. He got it back when he finally realize that he was not gonna get away with the slamming and kicking.cheesehead, no you are not a bad mom. Actually you are quite creative in your problem solving
Another option would be to use over the correction procedure and actually practice how to shut the door (shutting the door 50 times correctly might do it). 

I think that was a very logical consequence. Abuse it - Lose it. 
My husband did the same thing with both of our girls. They were both door slammers and my pre-teen daughter(no ADHD..etc) was the queen of slammers. She can be stubborn at times,but it works for her.
One day my husband had enough,go his tools out and took the door off. She was devastated,since she likes having her own space. It stayed off for quite a few days,then he put it back on and so far,we've only had a couple episodes.
My 8 year old(ADHD?) learned from her sisters mistake. So,even though she hasnt had that happen to her,she's learned by watching her older sister get punished and what will happen if you slam the door and/or kick it..
Yes,you were in the right..take that door right off and keep it off for however long you feel is needed.
What was his reaction when you took it off????
I think that is a wonderful idea. He wants privacy then he will have to earn his door back. Don't hesitate to take it back away again too....I think some kids will test us to see if we will take the time to do things again. I once took all the toys out of Isiah's room because he refused to clean them up or take care of them. He hated it but it was like he was testing us to see if we would do it again when he earned them back.You absolutely did the right thing.... and NO, you're not a bad mom! This is a great logical consequence! Next.......... if he start's abusing the stuff in his room besides the door.... STRIP HIS ROOM completely! I'm serious....... take every item out of the room except a mattress on the floor if necessary. Then he earns it back with good behavior. Some kids aren't phased by this strong of a behavioral modification technique......but many DO respond well. You don't know until you try it.
Okiemom
That is a great idea! I 5 year old does the same thing, and since it is an older door we have just been ignoring it, hoping that he will realize that it is not going to get a rise out of us.
I might try the practicing shutting the door correctly, and if it continues, then remove the door.
HA HA my mom took my door away for a week once when I was a kid, it worked and taught me a lesson.
