It can be so annoying when they do it because they sound so ungrateful and spoiled! Usually some physical stress-reducing activity or just a nice long talk will leave them feeling more centered. I think the root of the problem is sometimes that they don’t know what to do in order to relieve their anxiety. I usually don’t respond to the bored or what should I do comments and try to engage them in conversation about things they might be worrying about.

I hope that helps! I am obviously not be an expert on child psychology, but I know how my own brain works and worked when I was a kid. I can remember feeling like that and looking back I think . . .hmmm. .. this is what was happening to me!
