Why is it named for abortion when it's a neonatal death? It might be a miscarriage or a stillbirth, but you wouldn't get a legal birth and death of a child who wasn't delivered while they still showed signs of life, and that certificate seems to be literal since it appears with all the normal belongings.
Maybe it's a translation issue? I had to look up what the correct term in this situation would be, so I wouldn't blame you, but I do think it's really not a trivial distinction to make.
