What is step sibling definition?

Step siblings refer to individuals who are not biologically related but share a parent or step-parent due to remarriage or cohabitation. They are not considered legal siblings, but they may live together and share some family relationships and responsibilities. The relationship between step siblings depends on many factors, such as their age, gender, upbringing, personality, and family dynamics. Some step siblings may form strong bonds and consider each other as real siblings, while others may have less interaction or conflict due to jealousy, competition, or resentment. Step siblings may face challenges such as adjusting to new family members, dealing with blended family issues, and navigating their identity and loyalty to their biological and step families.
