Practices that may help

1. Use Plan B: the three-step collaborative conversation
   Empathize with the child’s concern, share yours, and invite them to solve it together.
   Collaborative Problem Solving (Ross Greene)
2. Hold Plan B conversations proactively, not reactively
   Solve the problem before the next explosion, when everyone is calm.
   Collaborative Problem Solving (Ross Greene)
3. Use empathy to de-escalate, not to capitulate
   Name the child’s emotional state without agreeing with every demand — empathy and limits can coexist.
   Collaborative Problem Solving (Ross Greene)
4. Recognize when Plan A (unilateral imposition) makes things worse
   Adult-imposed solutions can win the battle and lose the war — notice when enforcement is escalating rather than solving.
   Collaborative Problem Solving (Ross Greene)
5. Evaluate solutions for durability: realistic, mutually satisfying, safe
   A collaborative solution that fails one of three tests — realistic, mutually satisfying, safe — will not hold.

6. Easy Manner: bring a light touch when appropriate
   Use humor, lightness, and warmth to remind both of you that the relationship is bigger than this conflict.

7. Difficult Conversations, Made Practical
   The Harvard "Difficult Conversations" framework says every hard talk is really three at once — what happened, the feelings involved, and what it means for each person’s identity. The shift that changes everything is moving from blame to contribution and from arguing your story to learning theirs. It is a practitioner framework grounded in negotiation theory rather than controlled trials.
8. Adapt your conflict approach to the other person’s DISC style
   Conflict lands differently for each style — match your approach to reduce defensiveness.
   DISC Behavioral Styles
9. Identify the lagging skill behind the behavior
   Name the cognitive skill the child is missing, not the behavior you want to stop.
   Collaborative Problem Solving (Ross Greene)
10. Collaborative Problem Solving (Ross Greene)
    Ross Greene’s Collaborative Problem Solving model holds that kids with explosive behavior lack the cognitive skills to handle frustration and inflexibility — not the motivation. The approach replaces punitive consequences with structured adult–child conversations that build lagging skills over time. Randomized trials in clinical settings show significant reductions in explosive behavior, though most real-world evidence is clinical and observational.

• Every conversation with my kid about their behavior turns into me laying down the law and them digging in, and I want a way to actually talk it through together→

• Every time I put my foot down and insist, my kid blows up worse→
