Pitcher conferences

[jme]

In Dixie girls 10U game last night, visiting team had awesome pitcher (for this age group). What made the pitching even more intimidating was that between every other pitch, the first baseman (also, backup pitcher) would go to the pitcher's mound and talk to the pitcher while shuffling the dirt with their feet for about 15-20 seconds. Not a very long time, but nonetheless very distracting to the batters. Each time, the PU would take a couple of steps toward the pitcher, pause, then return to the plate as the first baseman went back to her position. Are there any rules on this? Can anyone explain the PU's actions?
