Here's an easy organizing idea that I relied on when the kids were little. Buy an accordian folder with 12 or more dividers. Decorate as desired. Label the dividers with the months. Now, every time you do a seasonal activity, craft or recipe, put it in the folder. Most importantly, write down the little details that you won't remember next year. For example, we used to always go to the same place for fireworks, but we could never remember where to park. We used to go to the same pumpkin festival, but always forgot to bring scarves and gloves. We always went to the same deli on the way to New Jersey, but always forgot what exit off 84 to take. We made the same recipe for Passover, but forgot if we preferred macintosh apples or gala. This file was a life-saver!
