An "Only Child" refers to a person who has no siblings. This means they grow up without brothers or sisters, which can influence their personality and social interactions. Only children often receive undivided attention from their parents, which can lead to strong bonds and a sense of independence. Research suggests that only children may develop unique traits, such as being more mature or self-reliant. They might also experience challenges, like feelings of loneliness or pressure to succeed. Overall, the experience of being an only child can vary widely based on family dynamics and individual circumstances.
