Share list of medications

As a parent of a child that takes medications, I would like to have an easy way to share this information with their teachers or babysitters, so they have access to this medication list.

The issue names no files, tests, or entry points. Start by locating the existing medication-list flow and clarify how the list should be shared, who may access it, and what permissions are required. Done should mean that a parent can share the medication information with teachers or babysitters and that the expected access behavior is tested.
