That is between you and your parents. I try to call home at least every other day, not for my sake, but just to let my parents know that I'm doing okay. Sometimes I get caught up and don't even call that often. If you want to call home, there is no set number of times that are okay its just how often you want to. Just be sure that you don't let homesickness get in the way of enjoying and adapting to college life.
