I have gone through this with my oldest (now 8) and am currently with my youngest (currently 5)
My oldest, once in a blue moon, will still have a full blown meltdown but not like he used to.
My question to you is , has anything changed in his environment where he could be over stimulated?
Increased academic load?
Is he going to a new place where it is very loud or very bright?
He has lost a friend or some relationship change?
With my oldest, I was very firm with him in his behavior while still listening to him and talking it out. Over the last 3 years, he has come a long way.
Even his teachers have remarked on the change.
My youngest is now doing the same and I am doing the same thing to him while adapting to his circumstances.
Best of luck, unless you opt for drugs, it will take some time to help him control the dissonance between his mid and his maturity
