We lost an infant son at 3 days of age. He was taken to one of the early NICU's at another hospital immediately after birth. I never saw him alive nor do I have any pictures of him. The only time I saw him was at his funeral and no one thought to take a picture. So I think this is a wonderful idea.
The idea of the picture is perfect. It makes the experience of the pregnancy, the hopes and dreams, and the loss so much more bearable.
I counselled a young woman whose baby had no chance for survival. Her family did not want her to go to the hospital to see him but I advised otherwise.
Later her doctor told me that it was in her best interest to go see her baby, touch him, and talk to him. It eased her pain after he died.
