Having lost a baby during early pregnancy, I can assure you that I wanted nothing more than to cling to any memory I had of my baby boy. I had nothing, though. I would do this.
When my grandmother died, my mother was going through the cedar chest (yep, Southerners) and found a small picture torn from a magazine. She had handwritten a note that said, "This looks a little like L____. I never had a picture of him."
My grandmother's first baby had died, and the only thing she had to remember him by was a picture torn from a magazine... of a baby who looked a little like hers.
