Thanks so much everyone! We just found out today that he is suffering from severe anxiety and migraines, in addition to the SPD, so that just adds to the melting pot. Those are two things I also have, so I understand how it feels. His pediatrician said it explains the sudden inability to cope. She also has a child with anxiety, so she remembers how bad it was before her child was treated. I'm just glad I'm not alone because most days it feels that way. Jack's teacher does the stoplight approach in her classroom, so it may be good for me to also incorporate that method into our home, since it would create more consistency. I LOVE LOVE LOVE the pushup idea!!!!!! We are also thinking about stepped up his OT to 2x week until he can get more stabilized. We'll see how things go! I certainly appreciate your input!
