Tough couple of days :(

So my sweet girl has had two pretty tough days at school. Lots of impulse-control issues. Trouble listening and paying attention. Seeing some of the same stuff at home, along with some mean outbursts and just a general, overall kind of bad mood. I'm not sure what's going on. I know it's going to take some time for the gluten and casein to get out of her system... but like my husband said, we can't blame gluten and casein every time she has bad behavior. Or can we? We don't know. I also had to take her off of her supplements until we have some more blood work done tomorrow... she hasn't had her DHA, probiotic, or multi-vitamin since Friday... so I'm wondering if that is contributing to this? I could just cry, because she was doing so well. The first couple of weeks of school were GREAT, and after talking with the teacher a week ago, who told me that she hadn't seen any indication in the classroom of our daughter's diagnoses, I was just so thrilled. That all changed on Tuesday, when her teacher asked to speak with me after school. :( I TRULY believe this... and I need to try harder to REMEMBER this when times are tough... but IT'S NOT HER FAULT. I know in my heart of hearts that it's not her fault. In the words of Dr. Ross Greene, "If kids COULD do well they WOULD do well. In other words, if the kid had the skills to exhibit adaptive behavior, he wouldn’t be exhibiting challenging behavior. That’s because doing well is always preferable to not doing well." Our daughter has truly shown me this, time and again, so I believe it. I just need to always remember it.
