Parent Involvement in Fed ???

[Multiple Sports]

Gentlemen,

My interpreter and I have are having a friendly debate over this one. I have over the years have disallowed parents catching their daughter who is pitching upon arrival on the field. Whether they are catching them prior to the start of the game, between innings on the side or even taking a few pitches behind the plate to help "speed the game up" as the catcher gets her gear on. I feel as those it is a liability if the parent throws the ball back and were to hit another girl in the face. ( I know that is extreme but trying to show the liability side ).

Lacrosse referees don't let fathers warm up the goalies and this doesn't happen in baseball. Just trying to get the brotherhood thoughts. My rules interpreter doesn't think there is a rule set to validate my thought process.
