This behavior is abnormal. You say he's in counseling outside of school, but it sounds like he needs actual therapy rather than simply counseling.

Your plan sounds fine, but that doesn't take away from how scary and unpredictable it all is. Has he ever been evaluated for SPED for emotional disturbance? I would doubt it since he's only in 2nd grade, but his reactions to normal situations are extreme. You could start by consulting with the district's school psychologist and/or behaviorist to get some strategies. If those don't work after a few months, then SPED assessment for emotional disturbance may be appropriate.

Also, does he have an outside diagnosis? Is he on medication?
