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 kids, providing emotional support, and ensuring their well-being. In a nuclear family, the focus is primarily on the immediate relationships between the mother, father, and their children. This setup can foster strong bonds and a sense of security, as family members often spend a lot of time together, creating lasting memories and traditions.
