I purchase several one-time-use cameras and place them around the house and in the car at holiday time. Our family has photographs of precious moments that would never have been recorded if I didn't do this. One such moment came the day I was gift shopping and the kids decided to search the house for their presents. A perceptive child picked up the camera and took pictures of the fun. I found out about their sneak preview when the photos showed up after being developed.
Each family member sees events from a different perspective. Let everyone share in the memory preservation.
