Last night difficult child 2 kicked easy child - and she's had enough. I drove her back to her other mom's house for the night, and we will be working out custody (we share 50/50) so that they don't overlap at our house. It's just so sad all the way around - but my partner and I were able to have a really good talk, and will follow-up with other parents, therapist, etc. DP and I are now much more on the same page that this is serious and needs some additional intervention - and I can tell she's starting to see that it's not because she's a bad mom, it's that he's wired differently. I'm sorry it took a Big Bang involving easy child - but I was really proud of difficult child 1 sitting down with her step-brother and explaining what happened to her when SHE couldn't get the impulse-control part a few years ago (we separated the sisters every time it happened...that drove home the message pretty fast). difficult child 2 is waaaay clueless - subdued this morning, knows he did something wrong, but of course its "not his fault" because nothing ever is. On the way out the door, I gave him a hug, told him I loved him and that sometimes an apology isn't enough to make things better, and that this would be an opportunity for him to learn... Can't concentrate at ALL here at work today! When's my copy of "The Explosive Child" gonna come?!?!?!?!?
