How to Help Siblings Get Along

Child Psych Podcast Episode #151

Sibling conflict can feel relentless. If your kids seem to argue all the time, it is not a sign you are failing. It is a signal that skills and connection need strengthening. Here is a parent-friendly guide inspired by Dr. Laura Markham’s Peaceful Parenting approach to help you move from refereeing to coaching.

Why Siblings Fight More Than You Expect

Frequent fights are messages. They often reflect dysregulation, jealousy after a new sibling, or a parent–child bond that needs attention.
Your one-on-one connection matters. Warm, consistent time with each child lowers rivalry.
Control invites more control. When kids are managed through threats or yelling, they copy that dynamic with siblings.

When To Step In During Sibling Fights

Do not sit it out. “Let them work it out” can lead to power wins and bullying before kids have the skills.
Be a calm coach, not a judge. Reinforce family rules like kind words and safe bodies without picking sides.
Lend your calm. Your regulated presence helps children think, speak, and solve problems.

What To Say In The Heat Of The Moment

Move close the moment you hear scarcity cues like “There are not enough.” Try this flow:

Name the problem and the rule
“You both want the magnet tiles. Our rule is kind words and safe bodies.”
Protect the turn
“Who had them first keeps the turn until the next meal. Then it is your turn.”
Help the waiting child cope
“Waiting is hard. I will sit with you while we plan what you will build next.”
Validate the hurt child
“That shove hurt your body and those words hurt your feelings. I hear you.”

Self-Directed Turns: A Simple System That Works

Long turns with a clear limit. The child who had the item first keeps it until a natural marker, like lunch.
Fairness through protection. Kids learn that their time will be respected, which reduces grabbing and chasing.
Practice waiting skills. Offer a timer, an alternative activity, and your attention while they wait.

See The “Aggressor” With New Eyes

Behavior is communication. High energy, low impulse control, and a sense that there is not enough can push a child into fight mode.
Assume regret once calm. Speak to the good in your child and the skills they are still building.

Repair Works Better Than Punishment

Sending a child away fuels shame. It may stop the noise but it does not teach what to do next time.
Repair means reconnection. Sit beside the angry child, reflect their experience, and own your missed cues.
Invite amends instead of forcing apologies. “How can you make things better with your sister?” allows genuine repair.

Teach Scripts Kids Can Actually Use

“I was using that. When can I have a turn?”
“I will be done after lunch. You can have it then.”
“Please do not call me names. I do not like it.”
“I need help. We cannot agree.”

Post these near common conflict spots to make practice easy.

Build Protective Daily Habits

Regular one-on-one time with each child. Even ten minutes a day protects against rivalry.
Mind your labels. Avoid “sweet one” and “needy one.” Reflect the whole child in both kids.
Add resources if scarcity is constant. Duplicate the most fought-over items or set clear turn rules.
Model calm problem solving. Kids copy what they see.

Quick Parent Scripts You Can Borrow

“You two are having a hard time. I am here to help. Our rule is kind words and safe bodies.”
“Emma is keeping her turn until lunch. Dylan, let us plan your build for after lunch.”
“You really wanted more tiles and felt there was not enough for you. That was hard. It is never okay to shove. I will help you tell me when it feels unfair.”
“I am sorry I did not step in sooner. What could make things better with your sister?”

Take Care Of You First

Regulate before you teach. Breathe, slow your voice, and remember both kids are yours to protect.
Notice your history. Old sibling wounds can color today’s reactions. If you feel hot, pause.
Lead with connection. Connection enables regulation. Regulation enables learning.

The Bottom Line

Coach, do not referee. Protect safety, co-regulate, name needs, and teach turn-taking with clear family rules. Choose repair over punishment. Your steady connection with each child is the strongest antidote to rivalry and the fastest path to a kinder home.
