How to handle sibling jealousy over a new baby

Sibling relationships often form the foundation for developing empathy and mastering conflict resolution skills in childhood. These connections can be some of the most significant and enduring in a child’s life.
However, the arrival of a new sibling can bring a mixture of emotions, including excitement, joy, jealousy, sadness, or even resentment. It’s natural for children to feel unsettled as their family dynamic changes.
The emotions of an older child often manifest in various ways:
- Physically acting out, such as hurting the baby.
- Verbalizing their feelings by saying they want the younger child to “go away.”
- Exhibiting challenging behavior with parents or caregivers, while being loving to the baby.
- Mimicking the younger sibling’s behaviors as a form of regression.
- Becoming withdrawn or reserved.
While managing these behaviors can be challenging, providing reassurance and focused attention to the older sibling can help cultivate a positive and supportive sibling relationship.
Understanding Sibling Rivalry
Sibling jealousy is a common and natural response to a new sibling’s arrival. This response could stem from an instinctive fear of losing their place in their parents’ attention or care, rooted in evolutionary survival mechanisms.
This behavior can even be observed as early as nine months of age, where a perceived “threat” might arise due to the need to share care and resources. Jealousy and rivalry can escalate when younger siblings exhibit negative behaviors like taking toys without asking.
However, the older sibling’s ability to control emotions can significantly improve the quality of the sibling relationship overall. Realizing this, parents can guide their children toward stronger bonds through encouragement, reassurance, and modeling positive reactions.
Practical Tips to Help Siblings Bond

Children are more likely to form positive relationships when favoritism is avoided and their emotional needs are met. A child who feels secure and valued in their relationship with their parents is less likely to exhibit jealousy or rivalry. Here’s how parents can foster harmony:
Before the Baby Arrives:
- Explain the upcoming changes in an age-appropriate, honest way.
- Use resources like books about having a baby sibling, available at local libraries, to help them prepare.
- Encourage the older sibling to express their feelings about the new addition.
- Observe their play. They may act out scenarios with toys or dolls, offering insights into how they feel.
- Give them individual attention and one-on-one time.
- Include them in preparations, such as picking a name or organizing baby items.
Once the Baby is Born:
- Regularly ask the older sibling how they’re feeling and assure them it’s normal to have a mix of emotions.
- Provide consistent love, reassurance, and focused time to help them feel valued.
- Encourage them to help with small, supervised tasks involving the baby and show appreciation for their efforts.
- Reinforce positive interactions, like gentle touches and talking kindly to the baby.
- If possible, enlist family or friends for support so you can dedicate one-on-one moments with the older sibling.
Parents who acknowledge their older child’s emotions and give realistic expectations can help them transition into their new role as an older sibling more smoothly.
The Benefits of Having Siblings

While sibling relationships have their ups and downs, they play a critical role in shaping emotional development, social skills, and even physical health. Siblings provide opportunities to learn how to interact, resolve conflicts, and empathize with others. These benefits often last well into adulthood. Specifically, siblings can help children:
- Develop empathy and compassion for others.
- Improve negotiation and listening skills during disagreements.
- Learn to manage emotions in socially appropriate ways.
Siblings also have unexpected health benefits. Studies suggest siblings influence the gut and airway microbiota of each other, reducing the likelihood of developing asthma or certain infections. Younger siblings, especially those close in age, build immunity through shared exposure to various microbes.
Additionally, family routines like storytelling, singing, and playing together strengthen bonds and improve emotional and social well-being.
Same-Sex vs. Different-Sex Siblings
When it comes to developing empathy, it doesn’t matter whether siblings are of the same or different sexes. The value lies in having a sibling who provides a perspective different from their own.
However, same-sex siblings may experience more comparisons and competition, which could affect their confidence. On the flip side, siblings of the same sex may be more likely to admire each other and serve as role models.
Does Age Gap Matter?

The age gap between siblings can influence their relationship dynamics. Siblings closer in age tend to have more similar personalities, which might strengthen their bond. However, younger siblings may compare themselves to the older one, sometimes leading to self-doubt, particularly when the gap is narrow.
Parents can support both children by avoiding favoritism and encouraging mutual respect to foster healthy sibling relationships despite age differences.
Challenges and Drawbacks of Sibling Relationships
Sibling relationships aren’t without potential drawbacks. Jealousy and conflict are common, but they can provide valuable opportunities for children to learn conflict resolution and the importance of compromise. Over time, these lessons can strengthen emotional intelligence.
It’s also important to remember that sibling relationships evolve throughout life. They might not be close as young children but could develop a stronger bond as they grow older. Parents can nurture these bonds by emphasizing the lifetime benefits of having a sibling and facilitating positive interactions.
Sibling connections, while complicated, are invaluable. With parental guidance and patience, these relationships can significantly enrich the lives of all family members, both in childhood and beyond.
