: No, the relationship is not that of a child package.

I suspect the questioner may have meant is every Ada package
a child of package Standard, in which case, the answer is:
"every 'root' Ada libary package is a child of package Standard."

Robert probably interpreted this question as "is every child of 
the package Ada also a child of package Standard?" and the
answer to that is: "no -- the children of package Ada are
grandchildren of package Standard."

To elaborate a bit...

Every library unit is a descendant of package Standard, and
is logically inside its declarative region.  The "root" library
units (like Ada itself, System, and Interfaces, plus those root units that
users choose to define themselves) are direct children of package Standard.
The direct children of these root packages in turn are effectively 
grandchildren of package Standard.
