Glad we all understand what you mean now.
To me, it sounds like you may have inadvertently created a really bad whining habit. He has learned that whining gets him what he wants. From his perspective, whining is not bad behavior, it's an effective communication technique he has been lucky enough to discover.
As a rule, once a habit like this has been well established, you will have to be really strong about not enforcing it. You should be prepared to let him whine for an hour at a time. *Ignore* him if he gives out a little peep. I wouldn't squirt him, just don't give him attention. If he whines on your lap, immediately put him on the floor and ignore him until he stops whining for, say, 30 seconds. Then you can say "good boy" and pick him back up.
It's just like with kids. If you give in every so often after he has been driving you CRAZY for twenty minutes, the next time he'll whine for forty, because hey, it just might work.
I agree you should probably take him in for a checkup just to rule out anything physical. If you can afford it, you can always bring a trainer to assess it too.
