Our oldest son first went to WDW when he as 8 yo, many, many years ago. He now has a son that is 3yo. For our son's birthday, my wife has gotten down the old photo albums and found some pictures from his first trip to Disney, like riding Dumbo and Autopia. Now, by chance our grandson, son's his 3 yo son, has already been to Disney and Mon took some pictures of him doing the exact same rides and things while at Disney that dad had done yeaaaars ago. So my wife is making a large scrapbook style picture titled "Like Father, Like Son" for his birhtday using these pictures. It really looks good!
