Can you ask the mom? We had a friend recently lose a baby under similar circumstances. I asked her if I could make a quilt out of clothes that he might have worn the few days he did live. She wanted to keep them whole and unwashed as the smell reminder her of the baby she lost. I took her meals, (she had 3 other children and was recovering from a c-section on top of everything). Each person is different. She grieved very openly, lots of comments on Facebook, etc. others are move private.
Someone else mentioned the photographer, she did have a photographer come to the hospital and take pictures. I believe it was free to her.
