What Is Sibling Jealousy?
Sibling jealousy is the emotional reaction children experience—marked by envy, resentment, or rivalry—when they perceive their sibling as receiving more attention, love, privileges, or resources from parents or caregivers. These feelings most often intensify during major family transitions, such as the arrival of a new baby, but can also emerge with changes in family structure, routines, or parental availability.
Sibling jealousy manifests in diverse ways. Younger children may express jealousy through tantrums, regressions, or efforts to disrupt parent-infant interactions. Older children and adolescents, on the other hand, might show their jealousy more subtly through sarcasm, withdrawal, or academic and social comparison. Even in adulthood, old wounds rooted in childhood rivalry can surface during family events, revealing the lasting influence of unresolved jealousy.
Importantly, siblings serve as each other’s earliest social partners. Early sibling relationships provide the first context for learning essential life skills: sharing, compromise, conflict management, empathy, and negotiation. However, when jealousy dominates these interactions, children can become locked in patterns of competition and emotional distress that hinder their growth.
Causes of Sibling Jealousy
The roots of sibling jealousy are varied and complex, often intertwining family dynamics, individual personalities, and developmental needs. Key factors include:
- Parental Differential Treatment (PDT): Children are highly attuned to differences in the way parents treat each child. Real or perceived favoritism—whether in affection, discipline, privileges, or parental time—can trigger jealousy and undermine trust within the sibling group.
- Developmental Stage: Sibling jealousy is most prevalent in early childhood (ages 2–6), when children are learning to assert independence while still needing significant parental support and validation.
- Birth Order and Age Spacing: Firstborns may react to the arrival of a new sibling with feelings of loss or displacement, while younger siblings may long for the status and privileges of their older brothers or sisters.
- Individual Temperament: Children naturally differ in their emotional resilience, competitiveness, and sensitivity to change. Some are more vulnerable to jealousy, while others may express it through aggression, withdrawal, or attention-seeking behaviors.
- Parental Stress and Family Environment: High-stress environments, frequent changes in routines, limited parental availability, or family cultures that model conflict as a problem-solving tool can all exacerbate jealousy.
- Comparison and Social Pressures: As children enter school, social comparison with peers and siblings intensifies, which may increase rivalry and feelings of inadequacy.
Additional triggers include tiredness, boredom, hunger, and even cultural or familial expectations regarding gender roles and birth order. Awareness of these factors allows parents to intervene before jealousy escalates into conflict.
Recognizing Sibling Jealousy: Signs and Symptoms
Identifying sibling jealousy early is key to preventing long-term rivalry. Symptoms can be behavioral, emotional, or social, and include:
- Attempts to gain parental attention by acting out, boasting, or feigning illness
- Competition in games or academics
- Angry outbursts, aggression, or defiance
- Low self-esteem, social withdrawal, or avoidance
- Manipulative tactics (trying to turn parents against the sibling)
- Depression or anxiety, especially if jealousy becomes chronic
Some children may also become overly compliant or strive to be “perfect” to win approval, which can mask underlying jealousy. Open communication and careful observation help parents address these behaviors promptly.
How Sibling Jealousy Affects Self-Confidence and Self-Esteem
The impact of sibling jealousy on a child’s self-confidence and self-esteem can be profound and lasting. Children who feel consistently overshadowed, compared, or less valued than their siblings are at greater risk for:
- Developing chronic low self-esteem and a negative self-image
- Experiencing anxiety or depressive symptoms
- Internalizing failures and setbacks as personal shortcomings
- Avoiding challenges due to fear of not measuring up
Social comparison theory suggests that children constantly assess themselves in relation to those around them—siblings being the most immediate reference point. When these comparisons are unfavorable, a child’s self-confidence can erode, undermining their willingness to try new things or persevere through difficulties.
Conversely, a nurturing environment where each child feels valued for their unique strengths fosters greater self-worth, emotional resilience, and positive relationships. Parents who acknowledge effort, celebrate individual successes, and provide opportunities for growth help mitigate the damaging effects of jealousy.
The Ripple Effect: How Sibling Jealousy Influences the Entire Family
Sibling jealousy doesn’t just affect the children involved; its impact often spreads throughout the family system. Unresolved rivalry can increase parental stress, disrupt routines, and undermine family harmony. In contrast, families who acknowledge and address jealousy build a stronger foundation for mutual support, communication, and collective resilience.
Parents who model empathy and fairness can help siblings move from rivalry to collaboration, strengthening both individual growth and the family bond as a whole.
Strategies for Preventing and Managing Sibling Jealousy
Effectively addressing sibling jealousy requires both preventative and responsive strategies that prioritize each child’s emotional needs. Evidence-based approaches include:
- Balanced Attention: Schedule regular, uninterrupted one-on-one time with each child. These moments need not be elaborate; even a few minutes of genuine, focused interaction each day can make a significant difference.
- Avoid Comparisons: Never compare siblings—directly or indirectly—in areas such as grades, behavior, or talents. Highlight each child’s individual progress and unique strengths.
- Encourage Cooperation and Teamwork: Create opportunities for siblings to collaborate, such as shared chores, family games, or joint projects. Praise teamwork rather than competition.
- Validate Emotions: Let children know that jealousy is a normal feeling, not something to be ashamed of. Help them find healthy, respectful ways to express their feelings and resolve conflicts.
- Positive Role Modeling: Model healthy communication, empathy, and generosity in your own relationships. Show how to solve problems peacefully and support one another during disagreements.
- Clear and Consistent Family Rules: Establish rules about respectful behavior, especially during conflicts. Involve children in setting these rules so they feel ownership and accountability.
- Set Aside Personal Space: Ensure each child has their own space, time, and belongings to prevent feelings of invasion or competition.
- Prepare for Triggers: Anticipate periods of high stress (before meals, bedtime, transitions) and implement calming routines or breaks.
- Teach Conflict Resolution: Coach children through disagreements, guiding them to find solutions and compromises without assigning blame.
How Can I Help My Baby Build Self-Confidence?
Babies are surprisingly aware of family dynamics, especially after the arrival of a sibling. To support your baby’s self-confidence:
- Provide predictable routines, soothing physical touch, and attentive responses to cries and needs.
- Encourage exploration and celebrate small achievements (rolling over, crawling, babbling).
- Foster secure attachment by being present and emotionally available.
- Avoid disruptions during important bonding moments, such as feeding or bedtime, and include older siblings in care routines to prevent jealousy.
How Can I Help My Toddler Build Self-Confidence?
Toddlers thrive on opportunities for autonomy and positive reinforcement. To build your toddler’s self-confidence:
- Offer simple choices: “Do you want the red or blue cup?”
- Praise effort and perseverance, not just results: “You worked so hard on that block tower!”
- Provide safe chances for independent play and problem-solving
- Encourage sharing and taking turns with siblings, modeling patience and praise
- Support the development of self-esteem by celebrating milestones and allowing toddlers to express feelings through words or art
The way you handle sibling dynamics at this age can shape attitudes toward self and others for years to come.
How Can I Help My Child Build Self-Esteem?
- Actively listen to your child’s concerns about siblings or family life
- Acknowledge their achievements and personal growth
- Teach self-compassion and coping skills for disappointments
- Encourage friendships and interests outside the family to reduce overreliance on sibling approval
The Role of Fairness and Parental Attention in Sibling Jealousy
Children often equate fairness with equality, but parents know that every child’s needs are different. Managing sibling jealousy requires parents to:
- Explain decisions openly and honestly. For example, “Your sister needs extra help with homework this week, but next week we’ll spend extra time with you.”
- Validate each child’s perception of fairness, even if their experiences differ.
- Balance privileges and responsibilities according to age and ability, not rigid equality
- Involve children in family discussions about schedules, rules, or special events, so they feel included and respected
Research shows that when children perceive parental decisions as fair—especially when the reasoning is explained and their voices are heard—they are less likely to harbor jealousy and more likely to develop empathy and trust.
Parents can model fairness by rotating special privileges (choosing a movie, picking dinner), praising unique achievements, and making time for individualized attention.
The Impact of Sibling Jealousy Across Developmental Stages
Infancy to Preschool
The arrival of a new baby often triggers sibling jealousy in toddlers and preschoolers. Common signs include regression (bedwetting, thumb-sucking), tantrums, clinginess, or attempts to “help” with the baby in disruptive ways. Older siblings may struggle to understand the shift in parental attention and routines, leading to insecurity or acting out.
Middle Childhood
As children mature, jealousy may shift toward comparison of skills, grades, or social status. Siblings might compete for parental approval, peer attention, or achievements. Unchecked jealousy at this stage can erode self-confidence and sow seeds of lifelong rivalry.
Adolescence
Adolescents become increasingly aware of differences in parental expectations, privileges, and support. Social comparison is at its peak, and the emotional consequences of sibling jealousy can include depression, withdrawal, or risky behaviors. Some teens may form alliances against a sibling, exacerbating conflict within the family.
Young Adulthood and Beyond
Unresolved jealousy can impact adult relationships, leading to distance, mistrust, or ongoing competition between siblings. Family gatherings can become sources of anxiety, and patterns of comparison may influence career, friendship, or romantic choices.
Being proactive in addressing jealousy at every stage helps foster healthy, lifelong sibling bonds.

Evidence-Based Approaches and Recommendations
Parents, caregivers, and educators can apply the following best practices to minimize sibling jealousy and nurture growth for every child:
Building Positive Sibling Relationships
- Organize regular family activities that promote collaboration and shared memories.
- Support and value each child’s unique interests, talents, and perspectives
- Encourage siblings to celebrate each other’s successes rather than compete
- Create rituals (special breakfast, weekend walks) that foster closeness and positive associations
- Allow siblings to resolve disagreements with guidance, intervening only for safety or persistent patterns of exclusion
Supporting Self-Esteem and Emotional Growth
- Model calmness and patience, especially during family disputes

- Group or individual therapy can help children develop coping skills, build self-esteem, and navigate sibling rivalry in a safe, supportive environment
Sibling Jealousy: A New Perspective
While sibling jealousy can be challenging, it is also a powerful opportunity for growth—for children and parents alike. Rather than viewing jealousy as a problem to eradicate, families can embrace it as a normal part of development, one that, when managed with empathy, guidance, and patience, teaches children to understand emotions, navigate relationships, and build resilience for life.
By prioritizing fairness, individual attention, open communication, and emotional intelligence, parents can transform rivalry into connection, preparing their children for healthier, more fulfilling relationships far beyond the family home.
