I've mentioned before how difficult child 2 used to be a easy child but since puberty hit has become more of a difficult child and then we got the Pervasive Developmental Disorder (PDD) diagnosis. Now I don't know what to think or do about his behaviors. Scenario 1: Both boys are getting ready for bed and start brushing their teeth. difficult child 1 goes into the next room to check on something while brushing and difficult child 2 starts later than difficult child 1 and stays in the bathroom, standing in front of the sink like he always does. difficult child 1 goes back into the bathroom to spit and rinse and difficult child 2 just stands there. difficult child 1 comes into the other room with a mouth full of spit to tell me difficult child 2 won't move. When I go in to tell difficult child 2 to move, he says difficult child 1"didn't ask me to move". This has NEVER been an issue until about the last week and it's not consistent. To me, it was almost like he didn't even realize difficult child 1 was there. Scenario 2: We're sitting at the table doing "partner reading" for one of their classes. difficult child 1 is reading. difficult child 2 starts cracking his knuckles (a new OBSESSIVE habit he learned from his favorite cousin). difficult child 1 tells him to stop. difficult child 2 starts tapping the book with a ruler. I tell him to stop. He starts to sniffle (allergies acting up) and we both tell him to stop. He gets mad and walks away from the table. When I tell him to come back because it's his turn to read, he sits down and starts reading REALLY quiet. Scenario 3: *Important information- we have 2 tv's on the main floor separated only by a wall both rooms with a sofa* Now, I was at work last night and both boys were home. After a couple hours, I get paged to answer the phone. It's difficult child 1 in tears telling me all the things difficult child 2 had done and that he wanted to kill him (sign that he'd been pushed WAY too far). I get difficult child 2 on the line and (because I can't leave work) tell him to go to the library NOW (his favorite place) until it closes at 5. I call him on my break later and ask him what happened. difficult child 2 was in the living room on the laptop with the tv going. difficult child 2 started tapping the dog kennel door (in the living room) because he felt like it. difficult child 1 got mad and went to take the doors off the kennel. difficult child 2 went over to the sofa and sat down and changed the channel. When difficult child 1 got done, he put the tv on the channel he was watching. difficult child 2 changed the channel again and walked out of the room with the remote and barricaded himself in another room. I asked him why he was kicking the kennel door and he said he was bored. Then I asked him why he changed the channel. His answer was "because difficult child 1 wasn't watching it" (he was taking the kennel door off at that moment). When I asked him why he changed it again after difficult child 1 turned it back and his answer was "because I was watching something." My guess is that he wanted the laptop and was willing to do whatever he could to get it, conscious or not. I am really struggling with these types of things. Part of me tells me that it's typical teen sibling rivalry stuff but, having made assumptions about difficult child 1's behavior and finding out how much damage I and others were doing with that, I am reluctant to do that now. I don't want to send difficult child 2 to the same place difficult child 1 went with all the discipline only to find out I was punishing him for skills he didn't have. I just don't know what to think or do. Do I punish or get him on medications? Is he just being a typical teen bullying his brother or is he really not seeing other points of view more frequently? His sensory needs seem to be increasing, too. The need for noise is almost constant now Any advice? Any insight? Anything????
