What sibling rivalry can really look like with ADHD (and what’s underneath it)

Sibling rivalry can feel constant in a home with ADHD.

It might look like:

• constant arguments

• one child always “starting it”

• tension over small things

• one sibling being targeted more than the other

And often, the child with ADHD is seen as the one causing the problem.

But what we’re seeing on the surface…

isn’t the full picture.

 WHAT IT CAN LOOK LIKE

Sibling rivalry with ADHD doesn’t always come from one clear reason.

It can look like:

• provoking for no obvious reason

• taking toys or interrupting play

• reacting quickly and emotionally

• becoming fixated on what the sibling is doing

• escalating small situations into bigger ones

And this can feel confusing and frustrating for parents.

WHAT MIGHT ACTUALLY BE HAPPENING

There are often multiple things happening at once.

An ADHD child may:

• be bored and looking for stimulation

• be drawn to what their sibling has

• be struggling to manage frustration

• be carrying emotions from earlier in the day

But there’s another layer that’s often missed.

THE EMOTIONAL DIFFERENCE THEY NOTICE

If one child is corrected more than the other…they start to notice the difference.

They see their sibling coping more easily, being told off less, and seeming calmer

And even if it’s not intentional, this can feel uncomfortable.

It can create a quiet sense of:

“Why is it easier for them?"

“Why do I get it wrong more?”

 WHY IT COMES OUT AT THE SIBLING

When a child is already holding that feeling…

it doesn’t take much for it to come out.

The sibling becomes:

• the closest target

• the easiest interaction

• the place where those feelings show up

Not because they don’t love them…

but because the feeling was already there.

WHY FOCUSING ON BEHAVIOUR ALONE DOESN’T WORK

If we only respond to the behaviour in the moment, we miss what’s underneath.

And that’s why it keeps repeating.

Because the behaviour isn’t the starting point.

It’s the result.

 WHAT HELPS

Instead of only reacting in the moment:

• notice patterns across the day

• Reduce comparison where possible- especially with others where you don't think your child is in earshot

• support both children differently

• build understanding, not just correction

And most importantly… recognise what your child may already be carrying

Sibling rivalry isn’t always about conflict between children.

Sometimes, it’s about what one child is struggling with internally.

And when that’s understood,

things can start to feel calmer over time .
