What does your mom-gut say? Does this seem like a "normal" tantrum (whatever that means...), or are you actually worried that something is wrong?
Dunno if this helps, but we had a saying in Girl Scouts that it's not normal for kids to behave well all the time. It helps me sometimes to remind myself of that.
Has something changed that might be throwing him off?
What set him off today? Is that the same thing (or similar to the things) that usually sets him off?
Were food and sleep normal today? In my experience, those are not to be underestimated as a tantrum trigger!
