I just wanted to share a tip that I found and used to help preserve the ultrasound pictures. My first son was born almost 2 years ago and his pictures are starting to discolor and get very dark. As I was googling, I found the idea to use nonthermal (NO heat) laminating packets. I picked up a package at Wal-Mart and sealed all of the pictures last night. It was easy and now they are extra sturdy. There's no guarantee it is going to work, but I figured it was worth a shot!
