I've got a box with Cooper's "congratulations" cards, the notes I kept of all his feeds (6 months worth!), going home outfit etc. I've also got a record book which has handprints, hospital bracelet, birth notice etc.

And my DH made a fantastic scrapbook. It has the front page of the paper from the day Cooper was born, a list of the Top 40 at the time, the AFL ladder, the TV guide for that day, prices of milk / Big Mac / petrol / postage stamp etc and many other pages. He did a great job.
