Sister-Mom

A sister who by blood is a sibling, but happens to play the role of Mother figure as well. (Sibling Co-Parenting)

This can occur for a variety of reasons such as cultural background, parents work schedules or simply having a large family.

Example 1: My sister-mom has helped me raise my grades, helped me focus on my future and is also my best friend.

Example 2: Teacher - "Hey, is that your mom over there? Is she picking you up from school today?"
Student: "Oh, no, that's my sister-mom."
Teacher: *confused look*
Student: "Well, she is my sister, but she also acts like my mom"
