Navigating Sibling Rivalry in Childhood

Sibling rivalry is a common phenomenon in many households often arising from jealousy and competition for parental attention.

As children grow, they may feel threatened by the arrival of a new sibling or perceive a shift in their parents' affection. However, there are several strategies parents can employ to help create a positive relationship between siblings, ensuring that their bond remains strong despite the occasional squabbles.

What is sibling rivalry?

Sibling rivalry or sibling competition refers to the competitive and often unfriendly relationship between siblings. Sibling rivalry can occur at any age but is particularly common between a preschooler and their younger sibling. This rivalry can manifest in various ways, including:

  • Fighting with sibling over toys or belongings
  • Crying to parents about their sibling's behaviour
  • Teasing or name-calling
  • Competing for parental attention
  • Refusing to share or cooperate during play

When does sibling jealousy typically start?

Sibling jealousy can begin as early as the arrival of a new brother or sister. For instance, a preschooler may feel neglected when parents shift their focus to the newborn, leading to feelings of jealousy. Some common examples of how your preschooler might feel jealous of their baby sibling:

As both children grow into toddlerhood or beyond, sibling rivalry can escalate, with both verbal and physical fights becoming more common. While these altercations can be concerning, they also present valuable opportunities for learning and development. Through conflict, children can learn important social skills, such as negotiation and compromise.

Why do siblings fight?

Every child will have their own reasons for sibling frustration or jealousy and this will vary between kids.

Common causes of sibling fights

While every child is different there are some common causes of sibling rivalry including:

  • Feeling left out: One sibling may feel excluded from family activities or conversations, leading to resentment.
  • Attention seeking: Children may compete for their parents' attention, which can result in conflict.
  • Miscommunication: Misunderstandings between siblings can lead to arguments over seemingly trivial matters.
  • Personality clashes: Different temperaments and personalities can create friction, especially if one sibling is more dominant.

What should I do when my children start fighting?

Sibling rivalry offers a golden opportunity to teach emotional regulation and conflict resolution skills. Here are some strategies to help when siblings fight:

  • Teach emotional regulation: Encourage your toddler to express their feelings verbally rather than through physical actions. For more tips, refer to our article on Teaching Emotional Regulation Skills to Preschoolers.
  • Promote positive relationships: Emphasise the importance of a good sibling relationship through physical and verbal affirmations. For additional guidance, see our article on Positive Parenting.
  • Encourage social skills: Help children understand how to interact with peers, preparing them for future social situations. Their ability to play friendly, negotiate and share with other kids is an important part of choosing between preschool or daycare and what will work best for them.

What can I do to help my kids have a positive sibling relationship?

It’s important to know that sibling fights are a normal part of growing up. Developing empathy and understanding takes time and patience. Here are some key tips to help encourage your kids to have a positive sibling relationship:

  1. Teach flexibility: Encourage your little one to be adaptable and not overly concerned with fairness.
  2. Prioritise one-on-one time: Spend individual time with each of your kids to make them feel valued.
  3. Promote team culture: Encourage a sense of teamwork within the family, and help siblings to support each other instead of fighting with their sibling.
  4. Prepare for new siblings: Help your older kids adjust to a new family member by involving them in preparations.

Family and sibling bonding activities for preschoolers

  • Scavenger hunt: A fun way to work together, encouraging cooperation and teamwork.
  • Jigsaw puzzles: Promotes problem-solving skills while working together.
  • Simon says: A game that helps them with listening skills and encourages laughter.
  • Hot potato: A fun, fast-paced game that promotes sharing and taking turns.

When should I seek professional help?

If you notice aggressive behaviour (either verbal or physical) that seems beyond normal sibling rivalry, it may be time to consult a health professional.

Signs that a sibling rivalry may be unhealthy

  • Frequent physical fights that lead to injury
  • Persistent verbal abuse or sibling bullying
  • Emotional distress in one or both siblings
  • Difficulty in resolving conflicts independently

A healthcare professional who specialises in childhood mental development can help you and your child navigate their emotions better. They can help develop healthier coping strategies, ensuring that sibling relationships can be a strong and positive influence throughout their life.
