A nuclear family is a family unit that consists of two parents and their children living together. This structure is often seen as the traditional family model in many cultures. The parents typically share responsibilities for raising their children, providing emotional support, and ensuring their well-being. In contrast to extended families, which may include grandparents, aunts, uncles, and cousins, the nuclear family focuses on the immediate relationships. This setup can foster close bonds among family members, allowing for a more intimate environment where children can grow and learn.
