Keep an Everything Datebook
Buy a weekly calendar. Jot down all the traditional things―school events, birthdays, appointments. But use it to keep track of nontraditional things, too. Write down bills that come through the mail and mark their due dates six days ahead. Plan weekly dinner menus and write them on the calendar. Use it to also record the kids' long-term assignments. That helps prevent those evenings of racing around to do everything at the last second.
