Hi, fudgecat, I'm not sure how prepared you can be, but here are the things that helped me.
The staff were excellent, professional but really caring and encouraged us to hold and care for our daughter.
Spending time with her and having a service with the chaplin.
Delivering her did help, and has also meant I could go home the same day when I had my third child this year. I still miss Ethel and my two boys are absolutly no replacement, but bring a lot of joy in their own right.
Finding people that will let you talk about your child.
Making the funeral as personal as possible, we both wrote poems.
For a while I was very angry at people who did'nt follow the advice given during pregnancy , after all I had and look what happened.
Ethel would have been 4 this November and we will go out for a family day to remember her as we have done for the last 3 years.
If your trust doesn't have a breavement midwife ( I was in the 40% that do)ask to talk to a councillor. Mine was really good and urged me to be kind to myself and that if their was anything I could concentrate on even for a short time I should do it- grief is an intense emotion and cannot be kept up 24hrs a day.
I hope this helps, unfortunately to echo what others said it can be quite an isolating experience
