Understanding Sibling Rivalry

If you’re raising more than one child, you’ve probably seen sibling rivalry in action, whether it’s a small squabble over toys or a full-blown argument at the dinner table. While it can be exhausting for parents, sibling rivalry is a natural part of growing up. The good news? With the right perspective, you can understand what’s normal, when to step in, and how to guide your children toward healthier relationships.

What Causes Sibling Rivalry?

At its core, sibling rivalry often comes down to competition and resentment. Kids may compete for attention, resources, or independence, and resentments can build when they feel another sibling has an advantage.

The 5 Types of Sibling Relationships

Not all sibling relationships look the same. Experts often point to five common patterns:

1. The Best Friends – Siblings who share a close bond, confide in each other, and truly enjoy being together.

2. The Rivals – Defined by constant competition and conflict, but also opportunities for growth.

3. The Caretaker & The Protected – One sibling takes on a nurturing or guiding role while the other relies on that support.

4. The Estranged – Siblings who have become distant or disconnected, sometimes as they grow older.

5. The Indifferent – A relationship marked by little interest in each other’s lives.

When Is Sibling Rivalry the Worst?

Research shows rivalry often peaks between ages 8 and 12. During these years, children are developing strong identities and becoming more aware of fairness, which can fuel conflicts.

If you have more than one child, expect some rivalry, it’s practically guaranteed!

What’s Normal (and Healthy) Rivalry?

Here’s some relief for parents: it’s completely normal for siblings to:

• Have strong feelings toward each other.

• Argue, fight, and disagree (sometimes loudly).

• Test boundaries as they figure out their place in the family.

In fact, these conflicts can help kids learn problem-solving, negotiation, and emotional regulation.
