Compares their children out loud
At dinner she asks why he can't just sit and do his homework like his sister does. At family gatherings one child is "the clever one" and the other "the sporty one", and both of them hear it.
Rule out first
Children far apart in age, when the older one really can do more and the comparison is about stage. A family or culture where naming each child's strengths out loud is ordinary praise. A single remark on a bad day, said once and not repeated.
What could explain it
Parental favoritism (differential treatment): One child is the yardstick most of the time. The same child gets more warmth, more leeway or less blame, and the other children can say which one it is.
Sibling rivalry and conflict: The comparisons come when the children are already fighting, as a way to end it. The fights get worse after them.
Family roles (golden child, scapegoat, lost child, mascot): Each child has a fixed label, the clever one, the difficult one, the easy one, and the labels have outlasted the facts.
Social comparison: The parent compares everything: the house to the neighbors', their job to a brother's. The children are measured the same way, against each other and against other people's kids.
Contingent self-worth: The parent's mood rises and falls with the children's grades, games or looks. The comparison is about how the parent feels as a parent.
Intergenerational transmission: They were compared to a sibling growing up and swore they never would. The words come out in their own parent's tone.
A next move
Look at who comes out on top. The same child, again and again, points to favoritism. Fixed labels that no longer fit point to family roles. Comparisons used to stop a fight point to sibling rivalry. A habit of measuring everyone points to social comparison. A parent whose mood follows the scores points to contingent self-worth. Words learned in their own childhood point to intergenerational transmission.
