beginning something new

I have known for months now that the gfcf has leveled off and he was no longer getting any help with it, he seemed to go completely backward, having tantrums daily and frequently, his ocd came back, he has to get it just right or he will keep repeating it. His communication is basically talking all the time and not really saying anything. He has not adjusted well to school, they are now using a sticker system and bribing him with little dinosaurs (his latest facination) just to get him to walk home with me. I am now seriously considering doing SCD with him. It eliminnates all starches and grains and sugars from his diet. the hardest one to do is potatoes and he has been off of those for about 2 weeks now and I have noticed a slight difference in him but not much. I am doing an insurmountable amount of research and I am planning every meal and snack he eats startying tommorrow. I know that it will be tough and I am planning to brace myself and get him through it. He has not really smiled and laughed since july and i miss his laugh and his smile, I know somewhere inside this angry, frustrated little boy is a happy carefree child and I am going to get him back, he is my little boy and I miss him.
