Somewhere I read it's a good idea to keep reading lists for your children of what they have read. Does anyone do this? What your method?

My DS9 reads 10 to 15 books a week. He reads everything from Whimpy kid books to Cricket in time square. It's hard to keep up with this demand. I keep thinking how will I ever keep this up he is only going into 3rd grade so I have a way to go.
