Sibling jealousy

Last edited: 4/15/2026

Overview

Sibling jealousy refers to feelings of resentment, rivalry, and emotional distress experienced by existing siblings when a new child joins the family. It is a common developmental challenge that can impact family dynamics and sibling relationships 2.

Diagnosis

  • Observation of Behavioral Changes: Increased irritability, regression in behavior, or withdrawal 2.
  • Emotional Expression: Verbal expressions of jealousy, anger, or fear related to the new sibling 2.
  • Assessment Tools: No specific diagnostic tests; relies on parental reports and behavioral observations 2.
  • Management

  • Sibling Preparation Classes: Formal classes aimed at preparing older siblings emotionally and practically for a new arrival 2.
  • Enhanced Parental Support: Increased one-on-one time with parents to reassure and strengthen the bond with existing siblings 2.
  • Open Communication: Encouraging children to express feelings and concerns about the new sibling 2.
  • Special Populations

  • Pediatrics: Sibling preparation classes are particularly beneficial for children aged 2-8 years to mitigate jealousy and foster positive relationships 2.
  • Key Recommendations

  • Include children in formal preparation for a new sibling through structured sibling preparation classes to enhance emotional readiness and reduce jealousy (Evidence: Moderate 2).
  • Provide additional parental attention and support to older siblings post-new arrival to maintain their emotional well-being (Evidence: Expert opinion 2).
  • Facilitate open communication channels for children to discuss their feelings about the new sibling, aiding in emotional processing (Evidence: Expert opinion 2).
