Ordinal place of the lost child (Hellinger's rule)

This is probably the rule with the greatest immediate clinical power in the Hellingerian systemic approach, and it's important to memorize it precisely: a deceased sibling—including miscarriages, voluntary abortions, lost pregnancies, and infant deaths—retains their ordinal place in the family system forever.

Practical implication: if a woman appears to be an only child but there were two abortions before her birth, systemically she is not the first, she is the third. If a man is the second of three living siblings but his mother had an abortion between the first and him, systemically he is the third, not the second.

This rule clinically explains symptoms that seem inexplicable: children who feel “superfluous” or “in the way” despite being only children, firstborns who carry the responsibility of several without understanding why, second children who feel “responsible for someone else's burden.” The rule names the invisible sibling and returns to each their real place.

The healing movement is simple: draw the genogram with all places occupied, name the lost sibling, say “You are the first. I am the second. Each in their place.” The peace this generates, according to clinical practice, is disproportionate to the simplicity of the gesture.
