Only children are individuals who grow up without siblings. This means they are the sole focus of their parents' attention and resources. Research suggests that only children may develop strong self-reliance and independence, as they often engage in solitary play and activities. Socially, only children can be perceived as more mature than their peers, as they frequently interact with adults. However, they may also face challenges, such as feelings of loneliness or pressure to meet their parents' expectations. Overall, being an only child can shape personality traits and social skills in unique ways.
