What family type can include children from previous relationships along with new children?

A blended family is characterized by the presence of children from previous relationships along with new children born to current partners. This type of family often forms when one or both partners enter a new relationship and decide to marry or cohabit, bringing together children from earlier unions. The incorporation of step-siblings and step-parents is a defining feature, creating a diverse family structure that may face unique dynamics and challenges, such as integrating different family traditions and bridging relationships between the children.

In contrast, a nuclear family consists of two parents and their biological or adopted children living together, which does not account for children from prior relationships. A single-parent family consists of one parent raising their child or children, typically without the involvement of a partner, while an extended family includes grandparents, aunts, uncles, and cousins, providing a broader network but not specifically addressing the merging of children from different relationships. Thus, the concept of a blended family distinctly represents the combination of previous and current familial ties, making it the correct answer.
