My SIL is very lucky that the kids section of the cemetary they are buries is just lovely.. very sad of course, but they are able to express themselves on the graves, and there are beautiful gardens and seats all around for them to sit and contemplate. It also looks over teh bay in Geelong, so its really nice.
How absolutely wonderful of the midwife to help you with photos and footprints. My SIL also has all these things framed, can I suggest when its not too raw you find someone who can frame these for you? I think you could do something really nice as a memorium with them.
I dont know what to suggest about getting out. I know I would fall to pieces in your shoes, and people would be the last thing you need to deal with. It does sound like you need a de-brief with the hospital, particularly since blaming yourself for any part of this is just not a good way to go. Regardless of what happened, none of it will ever be your fault.
