A step-parent is a person who is married to or in a long-term relationship with a child's biological parent but is not the child's biological parent themselves. This relationship often arises after a divorce or the death of a parent, leading to the formation of a blended family. Step-parents may take on parenting roles, providing care, support, and guidance to their step-children. In many cases, step-parents work to build relationships with their step-children, which can involve navigating challenges such as loyalty conflicts and differing parenting styles. The dynamics of these relationships can vary widely, influenced by factors like the age of the children and the circumstances of the family, including the presence of the child's biological parent and siblings.
