Weekly menus and grocery lists

With four little people in the house and activities that come with them, my schedule is a little crazy.  To make my grocery shopping and dinner prep go a little easier, I sit down once a week and make a menu and grocery list for that week.  I note the meal, what cookbook it is in and what page its on.  Then on my grocery list, I mark off everything I will need for that meal.  I do this for each day.  Throughout the week I add to my grocery list if we run out of "staples" and go grocery shopping once a week.
