A nuclear family consists of two parents and their children living together in one household. This family structure is often seen as the traditional family unit in many cultures. The parents typically share responsibilities for raising their children, providing emotional support, and managing daily tasks. In a nuclear family, the focus is primarily on the immediate relationships between family members. This setup can foster strong bonds and a sense of security for children. However, it may also mean less support from extended family members, such as grandparents or aunts and uncles, who might play a larger role in other family structures.
