One of the most traumatic situations a family can deal with is the loss of a child. The wound cuts deep into both individuals and relationships. It is agony to speak about and somehow the silence is worse. The entire world seems to come to an end.
And yet, life goes on.
The desire to be a parent doesn't pass with the loss of a child. After time has passed they may decide that the time has come to have another child. This subsequent child can come with psychological ramifications that don't exist with other children.
The parent(s) may treat the child as a Replacement Goldfish, or struggle with keeping the child from feeling like one. Fear of losing another child can cause a Mama Bear or Papa Wolf to develop into full blown My Beloved Smother.
On the other hand, the child may struggle with never feeling good enough. It can be hard enough to struggle with comparing to an older sibling; it can be downright impossible to compare with the unlimited potential represented by that older sibling's death.
My Sibling Will Live Through Me and Two Siblings In One can be related, specifically if the child is born close to the older sibling's death. Occasionally Truth in Television, especially historically.
Since this is a Death Trope, expect unmarked spoilers below!
