What's going on?
Sibling relationships are one of the longest relationships in a person's life. They are also intense, jealous, loving, competitive and confusing — all at the same time.
Small children fight over sharing, attention, fairness and identity. They are learning empathy, negotiation, and how to be a separate person in a family — and that learning is loud.
Your job is rarely to fix the conflict. It's to keep the dynamic warm and safe, and to coach skills over years.
Common signs and symptoms
Very common
- Fighting over toys, attention and 'fairness'.
- Big regressions when a new sibling arrives.
- One child taking on a 'good' or 'difficult' role in the family.
- Closeness one minute, fury the next.
Less common
- Physical aggression that is hurting one child repeatedly.
- One child consistently rejecting or excluding another over months.
Is this normal?
Yes — sibling conflict is normal and often a sign of learning, not a problem.
Practical things that help
1:1 time with each child
Even 10 minutes of undistracted time reduces competition for your attention.
Coach, don't judge
Naming what's happening ('you both want the truck') helps more than picking a winner.
Don't compare
'Your sister never does this' poisons the relationship for years.
Protect, don't punish
Step in to keep bodies safe; coach skills later when everyone is calm.
Notice the kindness
What we name grows. 'I saw you wait for him' is gold.
What can accidentally make it harder?
Asking the older one to be 'good' all the time
Quietly resents the younger sibling for years.
Big consequences for sibling fights
Punishment teaches secrecy, not skill.
These are gentle observations, not blame. None of us avoid all of them all of the time.
What should I say?
- “You're both upset. Let me hear from you first, then you.”
- “I won't let you hurt each other. I'm here.”
- “You are loved exactly as you are. So is your brother.”
Red flags and when to seek help
Worth an assessment
- Physical aggression causing repeated injury.
- Sustained exclusion, contempt or cruelty.
- One child consistently fearful of another.
Family therapy or child psychology if the relationship is causing sustained distress in one or both children.
If your child is seriously unwell or in danger, get help now.
