Here's my situation....
I'm creating a plugin that will allow families to register on the site I'm working on. Each family will have 1 or more children that they need to add to their registration. My initial thought was to make 2 custom post types - Family and Child and relate them either through metadata or through a custom table (1 to many joins).
My question is, is it possible in wordpress to create an admin page that would allow adding and/or editing of a family and all of the related children in one place (including adding, removing, and editing children as necessary)? If so, are there resources out there that can show me how to do it?
