I am a newbie to the softball world as I have only coached my son's travel baseball teams. I wouldn't let my son throw a bullpen everyday but my 11 year old daughter asks me daily to practice pitching. So is it like baseball to much is not good or is there a rule of thumb for how often a player should work on pitching? We try to play catch often to but I don't want to have her overdue it if it isn't safe,, Thanks
