A step-parent is a person who is married to or in a long-term partnership with a child's biological parent but is not the child's biological parent themselves. This relationship often arises when families blend after a divorce or the death of a parent. Step-parents can play a significant role in a child's life, providing support, care, and guidance. The role of a step-parent can vary widely depending on the family dynamics and individual relationships. Some step-parents may take on a parenting role, while others may choose to maintain a more supportive or secondary position. Building a positive relationship with the child often requires patience and understanding.
