S. J,
As a mother to 3 boys, ages 13, 5 & 2 1/2 I can give you and the other moms this piece of advice. REDIRECT their attention to something else. Ignoring them, telling them they are whining or telling them that you aren't listening while they are whining doesn't work. Get their attention on something else. They will shift their focus off of whatever got them whining in the first place. Playdoh, coloring, leapfrog videos, whatever it might be, just redirect the focus.
Good luck!
