Tiamummy, so sorry, I don't think there is a right/wrong way to do things, you just have to do what you think will help you. I do however realise that when you and your DH are involved that may not necessarily be the same thing. I think you need to explain to your DH what you want to happen and tell him why, I think he needs to do the same for you.
FWIW I did not have my little boy at my house ever, he died in hospital and the funeral was in an area where we did not live. What I did do though was take him a bag of clothes and wash things, toys, photos and gifts. Whilst at the FD he was in a moses basket when I visited. I bathed him, changed his nappy, dressed him, gave him a final cuddle and kiss and placed him into his casket myself. I then placed all the other items which were to go with him in the "right" places. I was not sure the FD would get things how I wanted them.
I visited him a number of times at the FD whilst my DH didn't see him after the day he had died. People need different things to grieve and you have to judge what is right for you, right for your DH and right for the family. I think the idea of having her come home for a few hours might be a good compromise however if your DH is only saying this for your beneift then make sure you let hime know exactly what would benefit you. If however he does not want her at home as he feels she is already gone then you may have to allow him that and meet him halfway. It really is so difficult and there is no correct way to do things.
DH did carry the coffin to the church and grave though and is quite proud to have done that for his son. Albeit it is something that he was not sure he would be able to do, the FD asked him if he would like to but if he broke down they would step in and carry him. I was on standby to step in regardless of how heavy he was and how recently after an emergency section as if DH couldn't do it by god I was going to do it. In the end he did manage it though. It isn't for everybody though.
We only had immediate family there, me, DH my Nana, Mum & Sister, FIL, SIL, BIL and his sister his brother was still in special care so I will deal with the guilt of him not atending in the future I think. After we went to FILs house for a cuppa and a snack. We didn't have a traditional wake/celebration of his life as it was so short there wasn't much to celebrate and only DH and I had met him.
Just try to do what you feel is right and hopefully you will get there together. Much love CM
