Santa is not happy

I can pretty much guarantee that Santa Claus is not pleased with the behavior that has been happening in this house. HT has decided that rules don't apply to him. In fact, if you ask him, "Do rules apply to you?" his answer will be no. He has been smuggling toys to school when he has been explicitly told that he isn't allowed to take them to school. If I don't inspect his back pack right before he walks out the door, he'll manage to smuggle them along. We are at our wits end with this, as is his teacher. He's also become quite good at back talking to me and yelling at me. AGH!!!! JC has also been difficult. Yesterday she decided to spit on her brother, basically because she felt like it, and of course he decided to spit back at her and then arms/hands began flailing in attempts to hit each other, and it's just ridiculous. We also learned yesterday that JC attempted to cheat on her science test. She said that she didn't understand the question and was looking over her notes to see if she could relate it to anything. We believe this, because she is having a great deal of difficulty in school understanding questions and concepts that aren't stated EXACTLY the way that she first learned it. For instance, she can give me a correct answer orally, but is unable to write an answer that makes any sense. She is also unable to choose a correct multiple choice answer because it isn't worded EXACTLY how she is looking for it to be. She's frustrated, and we are hoping that something can be worked into her IEP to help her with test taking. Her science teacher was extremely generous and allowed her to start over on the test after the notes had been confiscated. My husband is tired of coming home to tears and an angry mom over the behavior of (mostly) the youngest two. And the fact that Santa is supposed to be coming this weekend doesn't seem to be making any difference at all. Hopefully they'll get back on the nice list in the next three days!
