Sibling reactions are often manifested in:

• A. Academic decline
• B. Language delay
• C. No reaction
• D. Behavioral changes

Answer: (D)

When a family welcomes a new baby, the older sibling undergoes a big emotional and environmental shift, so their reactions show up most clearly as changes in behavior. The new baby demands attention, routines shift, and sleep can be disrupted, leaving the older child feeling jealous or insecure. Those feelings often express themselves through behavioral changes such as acting out, tantrums, clinginess, withdrawal, or sleep and toilet regressions. Academic performance or language development aren’t the typical first signs of this transition, and a complete lack of reaction isn’t realistic given the upheaval in the family dynamic. If the behavioral changes persist, it’s helpful to provide consistent routines, involve the older child in caregiving in a positive way, reassure them with attention and age-appropriate explanations, and seek support if the changes become severe.
