The batting order is continuous within the game and no player can sit twice until everyone sits once. I am just protecting the players who are scared of the ball and batting them last. I was one of those kids myself and remember the anxiety of the on deck circle. Obviously, it's my hope that by season's end this won't be the case.
So you think they are going to get less scared of the ball by batting them less?
For rec you mix the order up - get them out there as much as possible. I regularly bat one of the new players 1st or 2nd - often it is good if they have less time to think about it. Also hitting can be contagious - putting a less experienced batter behind a hitter will often get them a hit.
