Representing family relationships between Patients in FHIR (cross-posted to Stack Overflow)

Hello, this is my first post. I’ve cross-posted to Stack Overflow Please forgive me if that is not acceptable.

I need to represent a mother-child relationship between two Patient records in FHIR. The RelatedPerson model seemed like the most obvious to use for this, but it does not permit linking two Patient records. is only supposed to be used for linking multiple records that are for the exact same patient. How can I represent this relationship?


Generally it’s better to do one or the other. I concur with the answer provided there.
