Parenting the siblings
The hole in your family that can't be replaced. It's on you to help the brothers and sisters carry on.

When the natural progression of life and death is tossed asunder.

You, the parents, are also victims
The child who dies isn't the only victim.

Closure and acceptance can be made so much more difficult when no body is found.
