I lost the key...

This weekend, that sweet smile was noticeably absent from my son's face. The sound of laughter from a happy two year old was non existent. After several weeks of improvement on the GFCF diet, KC is worse than ever. My heart hurts for him. I don't even know what to do. When he flips his lid and throws food all over, the Mommy in me knows I have to teach him not to. I use time out usually, but at times like this it seems that he can't even control himself, so I feel horrible punishing him. I just can't let him think it's ok to do that. Chocolate pudding all over me, Gran, KC and the carpet is not ok. He asked for the pudding, then freaked when we opened the lid and put the spoon in. He ran off crying and my Mom and I were trying to figure out what the problem was and he ran back and before we knew it he had his hand in the pudding, grabbing out fistfuls and throwing it! A few times after, he asked for pudding and freaked out again when I offered it to him. I realized hours later that last time KC had pudding it was runny so I put it in a cup for him to drink. My only though is that it wasn't the same as last time. We also had throwing incidents with soy mac and cheese, and spaghetti squash also. With equally baffling reasons (to me). At one point he picked up a book and bashed the dog over the head, completely unprovoked. He's never done that. He cried so much this weekend, that my Mom and I were reduced to walking the floors with him, as he sobbed, many times. Some other odd things that happened before have started again also, such as picking at his eyes. He grabs the eyelash and pulls. He takes a pancake (or other food item), eats half of it, and then hides the rest and asks for more. He eats way more than usual. This stuff doesn't seem remarkable for a two year old, but these things all happen at the same time, and not independently. We took him to an open house at the fire station today. He wasn't afraid of the smoke simulator. He wasn't afraid of the fire trucks. But the plastic ducks in the pool freaked him out. KC LOVES DUCKS!!! I just don't get it. He just isn't the same kid. I'm going to call early intervention tomorrow and see what the heck is taking so long for the eval. I'm going to schedule the EEG that I've been putting off. He did have a few seizures today, although I only think that is part of the problem. I'm so scared. Something is wrong with him. He seems to be loosing his mind and I don't know how to help him. I'm his Mom. I'm supposed to know what to do. I'm not supposed to loose the key...
