secondparent
The term "secondparent" refers to an adult who plays a significant parental role in a child's life but is not the child's biological or adoptive parent. This can encompass a variety of relationships, such as a stepparent, a grandparent, an aunt or uncle, a long-term partner of a parent, or even a close family friend. The key characteristic of a secondparent is the consistent and nurturing involvement in the child's upbringing, providing emotional support, guidance, and care.
The concept acknowledges that parental figures can be diverse and that a child can have multiple adults
