Student database - Child relationship to responsible party

Hey Gang-

I'm curious. I'm working on a student database. I need to add a field that tells how the child and parent (or guardian) is related. As you know, the modern family is difficult. Kids live with aunts, grandparents, etc. So I'm just curious how I'd include that data in my db.

I currently have a "Parent" and Student table. So the parents, or responsible party could be linked to multiple kids.

Any thoughts? Thanks in advance!!
