Is there a single adjective that means "this person has lots of children"?
Context: I'm not actually talking about a person. I'm talking about a data structure in a computer program, where objects are organized in a hierarchical tree and each object can have few or many "child" objects. So "fertile", and similar words, are inappropriate. The object doesn't produce children on its own; the programmer must assign children to the object.

Merriam-Webster gives prolific:
The source is Latin proles meaning "offspring".
