Siblingitis is a playful term used to describe the occasional rivalry or conflicts that arise between siblings, often characterized by teasing, bickering, or competition for attention.

While it can be frustrating for parents, these interactions are often a normal part of growing up and can help siblings develop important social skills. Ultimately, siblingitis reflects the complex dynamics of familial relationships.
In the story "Ramona Forever" by Beverly Cleary, siblingitis refers to the tension and rivalry between siblings that Ramona experiences with her older sister Beezus. Ramona feels a mix of envy and admiration toward Beezus, leading to conflicts and misunderstandings between them as they navigate the ups and downs of sibling relationships.
