I feel ridiculous posting this, but I'm completely out of ideas. We've been in school for almost a month and I have a Kinder student on my caseload who still cries the entire day. He screams during drop off as staff pry him off of his mom. He screams during large group, breakfast, and just stands and screams during the entire portion of work time. I have no idea how he doesn't get tired of it. He has some language delays, but very much understands expectations and whats happening. It's gotten to the point where the other students are starting to get upset and are covering their ears. We've tried highly motivating reinforcers, worked with mom to create social stories about school, used food to motivate him, let him choose preferred activities, etc., but he just cries that he wants to go home or that he wants his mom. At the end of the day, he stops screaming, runs to her, and smiles and waves back at us. Any ideas?
