Oh, that's so heartbreaking. I'm glad you at least recovered your photos. And thanks to LJ, you have journaling that will help you remember the cute things the girls said and did (and voice posts to capture how cute their voices are at this age).
When Alexis was 3 (four years ago), we went on a field trip to a pumpkin patch. Somehow my camera bag was left open, and several rolls of film fell out. I don't know how many I lost...I did find a couple of them. I was just sick. There was no way of knowing how many I had lost, where they had been lost (in the large and muddy field, the wagon, the picnic area?), or (and this hurts more) what was even on the film. That's right, I wasn't sure what memories I had lost or how many.
It still makes me sad, but not nearly as hurt as it did years ago. So, there's hope that your sadness will fade some, too. :)
Hugs. And oh yeah, and that was pretty amazing of Chris. Techie husbands rock, don't they? lol
