I do alot of things to create physical and non-physical, memories, to leave as family heirlooms. One cute thing I do is that for each grand-daughter, I bake a special cake for their birthdays. For each granddaughter, I decorate the cake with either a sleeping beauty, cinderella, or ariel tiny doll. They come with their little mice, or fish or whatever is appropriate to each character. When they get older, a time when they have their own families, each granddaughter will get the little character that has decdorated thier cake for their entire young life.
