Switching Batters Boxes in Pony baseball

[Pete in AZ]

I was asked by a buddy to help him in a Pony tournament a couple weeks ago. They played on a 90' field but everything else was supposed to be Pony rules. I'm on the plate for game 1 and the one team is toying with the other. The pitcher is having a hard time throwing strikes so the coach has the batters switch sides after a few pitches. The first one caught me but the next kid I stopped. The coach said that Pony rules allow it and told me I was wrong. I let it go for the next couple innings until they had a ten run lead and it was over. Can you switch batters boxes during the same at bat in Pony ball? Thanks!
