The claim

The "only child syndrome" refers to the belief that being an only child can lead to particular personality traits or behaviors, such as being selfish, spoiled, or socially maladjusted.

Rating

Rather than attributing certain behaviours to being an only child, parents need to focus on fostering positive social interactions and setting appropriate boundaries. It is a myth, constructed on flawed research and outdated beliefs. A supportive and nurturing environment, coupled with opportunities for socialisation, can help any child thrive, regardless of family size.
