Sometimes sibling rivalry goes beyond bickering over cookies and into destructive territory. One father turned to Reddit after his youngest daughter deliberately destroyed her sister’s art portfolio, a collection of drawings that had taken months of work.
As punishment, he bagged up and threw away her rock collection, sparking a clash not only between his children but also with his wife, who thought he went too far. Reddit’s response? A divided but passionate debate over empathy, consequences, and the line between discipline and cruelty.

Parenting experts often say that discipline should be proportional and constructive, not purely punitive. Faith’s behavior, destroying her sister’s art over a cookie, signals deeper issues than sibling bickering.
Psychologists call this “disproportionate retaliation,” where the punishment a child dishes out far exceeds the trigger. Left unchecked, this pattern can escalate into more serious conflicts later in adolescence.
Research published in Child Development notes that harsh or inconsistent discipline can increase hostility between siblings rather than resolve it. The father’s wife raised a valid point: grounding or structured consequences may have been healthier than tossing the rocks. But there’s also a counterargument.
Dr. Laura Markham, parenting expert and author of Peaceful Parent, Happy Kids, emphasizes that kids need to feel the real-world weight of their actions. “Children learn best when they can connect their behavior to its natural impact,” she writes. In this case, losing a cherished hobby mirrored the emotional devastation Jane experienced.
But the bigger issue here isn’t just the punishment, it’s the family dynamic. Commenters pointed out that inconsistent parenting (mom rarely following through with groundings) may have emboldened Faith. Studies show that when one parent undermines the other, children learn to exploit the gap, weakening discipline overall.
So what’s the solution? Beyond punishment, this family needs consistent consequences, therapy that addresses sibling animosity, and protective measures, like locking Jane’s room or digitizing her artwork. While the father’s decision may have shocked Faith into reflection, long-term repair will require more than lost rocks.
