A child ca belong to more than one parent can't it?
Shouldn't "mtoto wenu" also be right?
I'd say that most children have more than one parent :) Anyway, you're right of course, mtoto wenu should be accepted.
I do not understand why this sentence is in a lesson about locatives. Should it be somewhere else / have at least something like "yuko bafuni" added?
