The situation
One of your older children borrowed a hoodie, charger, or game without asking, and the other found out. Now there’s yelling, door slamming, or silence and eye-rolling. Each is sure the other is being unfair, and both look to you to decide.
Right now
- Check safety first. If there’s shoving, threats, or anything physical, calmly step in, separate them, and keep everyone safe before anything else.
- Give them a little space to cool off. Say you’ll talk once everyone is calmer, and name a time, such as after dinner.
- Stay out of the judge’s chair. Let each person tell their side, one at a time and without interrupting. Reflect back what you heard.
- Name the real issues underneath, such as privacy, trust, and feeling disrespected. Respect each child’s boundary and acknowledge the other’s feelings too.
- Ask them to propose what would make it fair, and help them turn it into a simple agreement. For example, ask first, say no sometimes, or lend items under certain rules.
- Don’t force an apology or a hug. Repair can come later, in their own way.
Words you can try
- “I’m not taking sides. I want to hear from each of you, one at a time.”
- “It sounds like you felt disrespected when it was taken without asking.”
- “It sounds like you didn’t think it was a big deal, and now you see it was.”
- “What would feel fair to each of you?”
By age
- Ages 9–12
- Keep the conversation shorter and more structured, and make sure each child gets an equal turn. A written list of simple house rules about borrowing can help.
- Ages 13–17
- Respect their need for privacy and autonomy. Treat them as co-designers of the agreement, and let them hash out most of the details themselves. Step in only if it stops being respectful or safe.
Practice together: Ask, answer, and agree
- Choose a calm time, and tell both children it’s about making things easier, not about who was wrong.
- Each child finishes the sentence: “It’s easier for me when you…” and the other repeats it back.
- Practice a respectful ask (“Can I borrow your charger?”) and a respectful no (“Not this time, but you can use it Saturday”). Take turns.
- Write down two or three agreements that both can accept, such as what can be borrowed, how to ask, and what happens if something is broken.
- Plan a time to check in on how the agreements are working.
Talk about it
- What did you need in that moment that you weren’t getting?
- How might your brother or sister have seen it?
- What’s one rule about sharing that would feel fair to both of you?
Follow up later
In a few days, check in with each child separately: “How are the agreements going?” Tell them one thing you noticed that they handled well, such as asking first or taking a no calmly.
A note on safety
If the conflict includes hitting, threats, intimidation, damage to property, cruelty, or one child being repeatedly targeted or afraid, it isn’t an ordinary disagreement. Stop it right away, keep everyone safe, and talk with a pediatrician, school counselor, or another qualified professional if it continues or you’re worried.
