I'm really sorry for your loss. I can't imagine the pain you and your family are going through right now.
My wife and I had to deal with 3 miscarriages, but all of them happened within the first few weeks of pregnancy. So while it's still a huge pain we went through I think it's nothing compared to having a stillborn baby and a baby funeral to deal with.
About the large meal after a funeral, we do that too in Germany. It's called Leichenschmaus (literally "corpse feast").
