I'll tell you what we did and why.
My H was the same. He didn't want to see her or hold her but when it came to it he did.
We took photos as I was worried we'd regret it if we didn't. I've only looked at them twice and they safe in the memory box in the attic. I've put them double wrapped with a warning on the envelope so no one looks inadvertently. We ordered them on the free prints app. Then deleted them from the phone and cloud.
The nurse said the baby was too small to take foot or handprints which shocked me to be honest. But the funeral director did it for us. They are blurry and not really a proper print but I have them and I'm glad I do.
We didn't have a funeral because I felt very private about it all. The funeral director was a free service and literally picked her up from hospital after the post mortem and brought her to us. We buried her ourselves in a little field my dad owns and planted a tree there to mark the spot.
I originally chose to have her cremated but (and this was upsetting and shocking) the funeral director said that sometimes with small babies they struggle to retrieve any ashes and I would've hated to not know that and gone ahead which is why I'm saying to you.
The post mortem came back inconclusive which was a terrible disappointment but I'm glad we tried to find the answers.
Everyone is different and you may not do anything that we did but I thought it might help to know.
