My son was
My ds finally got an IEP after me fighting for 3 years. The only help he gets is through the OT at school. It says in his IEP that his sensory issues have an adverse effect on his learning or something like that. His handwriting is also a big issue. He was diognosed by a neuropsych with dysgraphia (inlegible and/or can not make letters/numbers correctly/right size). His OT works on his fine motor skills, writing, and sensory with him. He uses sensory accomodations in the room.
He has a wiggle seat, a fidget thing that goes on a pencil, a chewing tube that goes on a pencil, and he has fidget balls. All of this is to help him in the classroom. He also does theraputic listening 2x a day at school.
My suggestion is to talk to the teacher, bc in our situation for all my kiddos, it has to have an adverse effect academically. I was so sick of hearing it doesn't effect him acedemically I was ready to scream. But the neruopsychs report helped me out, although that report said nothing about sensory.
