What is the definition of "stepfamily?"

A stepfamily is a family that forms after the remarriage of a divorced person that may include one or more children. For example, "The Brady Bunch" television show represented a stepfamily.

Men and women who remarry with children merge their families together to form a new family that shares parents and stepparents. According to Help Starts Here, blending a stepfamily can be difficult if the remarriage occurs shortly after the divorce or loss of a parent. The children of a stepfamily must learn to live with new siblings and a stepparent that may not have the same beliefs and guidelines as their former family structure had.
