“How to End Sibling Fighting Peacefully”

My heart races as I listen to my kids in the other room. I can tell their play has taken a turn and is now getting sticky. I listen a little longer to see if they can work it out. Nope — things have escalated. I move quickly, hoping to break it up, but it’s too late. My youngest is crying and yelling, while my other kid still looks like they want to hurt someone.

I hate seeing my kids fight. I do all I can to prevent it, but it is inevitable. Siblings fight, and that’s normal. (Even as a therapist, it’s hard for me to accept this!) What I can control is my response to the fighting. I can step in, set loving limits, and try to teach my children that, while some conflict is normal, there are productive ways to manage emotions and handle disagreements so that things can go a little better next time. Here’s how I, as a therapist and a mom of three, including a child with ADHD, manage sibling conflicts in my home.

1. Do not take sides. This one is hard — if one kid is crying, then we often assume that the other one must be at fault, right? No, not necessarily. (The crying kid, for example, might have been bugging their sibling all week until they hit a breaking point.) The point is, fault is somewhat beside the point. It’s best to approach sibling fights with the understanding that your kids are dysregulated, struggling, and in need of your help.

2. Wait to talk. If children have reached the point of fighting, then they’ve reached the point where they’ve “flipped their lid” as psychiatrist Daniel Siegel, M.D., puts it. This is when the thinking part of their brain goes offline. It takes about 20 minutes to regulate and get out of this fight-or-flight mode.

If you try to talk to your children before their brain comes back online, they will likely not be able to take in what you’re saying, no matter how logical or comforting your words may be. If anything, you’ll just add to their stress response.

So, what should you do? Separate your children if possible and wait. Tina Payne Bryson, Ph.D., refers to this as a “time in” in her book co-authored with Siegel, No-Drama Discipline. Give your children time and space to allow their prefrontal cortexes to come back online. If needed, remind them about self-regulation tools, like deep breathing, counting to 10, or listening to calming music.

3. Approach each sibling separately. In private, talk to each child about what happened, and don’t assume that you know what started the issue. Even if you do know, allowing your child to explain will help them feel better. (Think about how you, as an adult, feel when you get to explain yourself instead of being shut down.) When a child feels heard and understood, it helps regulate their nervous system. They can calm down quicker and think more clearly.

4. Validate and acknowledge. Talking to your children separately will also give you space to validate feelings without making anyone feel bad or like you’re taking sides. If your child says, “She always takes my stuff without asking! I am never going to let her touch anything of mine again!” You can say, “I’d be angry, too, if someone touched my things without asking.” Or, “Yes, it is hard to have a sibling who often takes your stuff without asking.” Never make your child feel like what they’re upset about is trivial. It’s never a small matter to them, and brushing off their feelings will only intensify them.

Contrary to what most parents fear, validating your child won’t cause them to double down on their anger or commit to, say, NEVER let their sibling touch their stuff again. Validating will simply allow your child to vent and regulate.

5. What could you do next time? Finally, the step where many of us would like to begin: the conversation about how the situation can be handled differently next time. It’s tempting to jump straight to lessons learned, but this is a conversation that can only be had once brains are back online and everyone is regulated.

The conversation can start like this: “Hey, I know it is really hard when your sibling takes your stuff without asking. Is there another way this could be handled?” Giving your child a chance to problem-solve will strengthen this essential skill and help them feel more in control.

Offer ideas if they need help, like, “If you see your sister playing with your stuff, you could say, ‘Hey, you did not ask me to play with that. I’d like for you to ask me before you grab my stuff, please.’” On your end, notice if any patterns come up around fighting. Are fights happening when routines are disrupted? When one child feels ignored? When one child has too much pent-up energy? When your children are hungry or thirsty? When rules and expectations are not fully understood?

Big emotions are normal, especially if you’re raising neurodivergent children. But you can teach your children to regulate and resolve conflicts by meeting them with curiosity, compassion, and understanding.
