So sorry to hear you are going though this, its something that is so unexpected but so life consuming, it can be hard to understand what is happeneing.
My Daughter Ophelia was still born last April, her birthday will be next friday. I guess I count myself lucky as I didnt know she had died I went into spontaneous labour and found out she had died when I got to the hospital.
I didnt think of taking photos, it didnt cross my mind, but the midwife suggested it, she was so kind, saying how beautiful she looked, as she was laid on the bed to dress her. The midwife got a disposable camera and took a few pictures for us.
I could not look at them for a while, but now they give me comfort, they make me cry, but at least I can see her face I know what she looks like.
Dont force yourself, go with your emotions on the day, dont be forced into anything you are not comfortable with, but maybe try to think how you would like to remember your baby boy.
I have a memory box, with Ophelias pictures in, it has photos of me while pregnant. Also it has the tie my husband wore during her funeral. I also wrote a few pages in a book about her birth, I needed to write down how I felt about her. I felt I needed to acknowledge her.
We also have her footprints and hand prints, these are so precious to me. We are also lucky to have a lock of her hair.
I wear a locket around my neck with her picture and her hair in it.
I hope mn gives you the support that it has given me, it is sad to know that others have been through what we have, but it is also comforting that there are others who know what we are going through, they will not judge us for our feelings. They understand the different ways grief will take us.
If you find it all to much, please post on here, some one is always around to offer a hand to hold and a ear to listen.
