A whole family change

Jon decided on a wish. "I wish that over the course of the next 24 hours, in which we will all stay awake through, and not have to work or go to school, my family and I would regress in age into infants, then regrow up into the opposite gender, all stopping at our original ages. I wish that my whole family would notice the changes as they occur, find them strange but not freak out or tell anybody outside the family until i've decided."
