When your kids can't get through a Saturday without a fight breaking out
Two of them, one controller, and within thirty seconds it's a shouting match over whose turn it actually is. You've heard both versions of this fight a dozen times, and neither kid is lying. They're just remembering it in whatever order makes them the reasonable one. You take the controller away and now everyone's mad at you instead of each other. If this is a normal Saturday in your house, nothing is wrong with your kids.
What's actually happening at 6 to 8
By six to eight, kids can start doing more of the real work in a conflict: naming what they wanted, and actually hearing what the other kid wanted, instead of just arguing over what happened. That's a different skill than knowing a rule got broken. It treats a fight as two unmet wants running into each other, not a behavior problem waiting on a punishment.
The approach comes from Ross Greene's Collaborative Problem Solving framework, laid out in The Explosive Child: an empathy step to gather each kid's concern, naming the problem plainly, then an invitation to brainstorm a fix that works for both sides, child first. Greene's core claim is that a kid who can't work through a conflict yet is missing a skill in that moment, not choosing to be difficult. The specific move below, handing him the mediator job, isn't from the book itself. It's practice wisdom, tested in real houses, and we say so on purpose.
The script to try tonight
When the fight starts, instead of solving it for them, hand one kid the mediator job:
"You're the mediator this time. Ask your sister what happened and what she wants. Then tell me both sides."
Stay close enough to step in if it stalls, but let him run the questions. If the same fight keeps coming back, the remote, who sits where, don't wait for the next blowup. Pre-solve it at a calm moment instead:
"This keeps happening. Let's figure out a rule for it right now, before it turns into a fight again."
Let both kids weigh in on the rule itself. A rule they helped build tends to hold up better than one you hand down mid-argument.
What a week of this looks like
One good mediation gets you through tonight. What shifts the pattern is pre-solving the recurring fights instead of just refereeing the same one on repeat. Day one, name the mediator job as a real role, maybe alternate who holds it. By midweek, pre-solve one repeat fight at a calm moment, before it flares. By the end of the week, watch for him starting to ask the questions on his own, even a rough version of them, before you have to prompt.
This is what the Greenhouse app runs, one trait at a time: it sends you the day's move each morning and asks you once a week whether it's moving. A tip fixes a Tuesday. A program builds a kid.

Questions parents ask
Is it normal for siblings this age to fight constantly over small things?
Yes. Most sibling conflict at six to eight isn't really about the toy or the turn. It's about who gets to be right, and that matters more to them right now than the object does. What's developing isn't whether they fight. It's whether they can eventually name what they actually wanted, instead of only what the other kid did wrong. Watch for that shift, not for the fighting to stop.
Should I always make them work it out themselves?
No. If either kid is too upset to think straight, forcing a negotiation just stacks a second failure on top of the first. Give the mediator job on the fights that are heated but not overwhelming. Save the calm pre-solve conversation for the ones that keep repeating.
What if one kid always ends up as the mediator and the other never gets a turn?
Rotate it on purpose. The skill you're building is running the questions, not just deferring to whoever's older or louder that day. Both kids need practice hearing the other side said out loud, not just having their own side heard.
When is sibling conflict at this age a sign of something more?
If one kid is consistently afraid of the other, if fights involve real physical harm rather than shoving, or if a kid seems to be targeting a sibling specifically and it's getting worse over time, bring that to your pediatrician with specifics. That's not something an app should try to sort out. Greenhouse is built to say so plainly: when something looks beyond coaching, it tells you to see a person, not a screen.
