Request a Functional Behavior Analysis (FBA) to create a Behavior Intervention Plan (BIP).
If he’s in a public school in the US, and his behaviors are related to a disability, then the school has to support under IDEA (federal law).
Even further though, is the fact that behavior is communication. When he has a specific behavior (like feeling), what is the REASON for it? This is what the FBA process will explore, document, and create strategies to address.
I strongly recommend the books Lost at School and The Explosive Child, both by Ross Greene. He explains these behaviors and offers solutions.
