Can a child have more than one parent?

[Beginner]

I'm trying to design an OO system but I'm having trouble. Does it makes for
a child object to have more than one parent?

[Beginner]

IOW, is it considered good design practice for an object to have, for example,
4 different parents? I've got a gut feeling this is bad design, but I can't
quite put my finger on why.

It depends on what you're doing. For example, a HumanBeing class would
certainly have two parents, whereas an Amoeba class would only have one.
Simple tree structures use one parent per node, but a more complicated
structure could have several. Maybe if you explain the larger picture you
will get some better advice.
