How does a child find its parent?

[Mike Bernhardt]

In this case, the root only knows the external public server, not the
internal parent who is doing the delegating. So it would seem that slaving
the internal parent is the only solution for resolving hosts in the internal
parent domain, correct?

The child doesn't know it's parent and goes up to the root like any other
server would.

Reading the section on delegation in the O'Reilly book, I'm confused about
something: The parent is configured to delegate the subdomain to the child
with glue records, etc. But how does the child know who to ask if a host in
the subdomain requests a record in the parent zone? They don't show any
configuration example for that other than making the child a slave for the
parent zone.
