My Mom has an established tradition with her granchildren which is just one of the many ways she shows her love to them. On her refrigerator is a list on which her grandchildren can write down what it is that they have borrowed from her. That primarily is movies but my nephew Jackson has added to that by listing specific toys that he wanted to take home to play with.
Many years ago Mom began to occasionally purchase a new video if it were particularly suitable for children. The grandchildren could watch it at her house while visiting. Over the years she has built up quite a collection. Now she buys movies on DVD and they are more suited for whole families as many of the children have gotten older. Some years there are a lot of great movies worth buying and other years not as many that she would want them to see.
Each kid can borrow one movie until they come back to visit the next time. I can't tell you how much they look forward to this!!! They LOVE having this special privilege. Almost every visit to Grandma's house includes the return of a movie and the choosing of another one. This system is in my mind extremely efficient. Mom's purchase of one movie will be viewed by over thirty people, multiple times.
Even her great-grandchildren know about her lending tradition! It makes me so happy that my grandson is now borrowing from me in the same way, with a list on the refrigerator!
