I notice two distinct types of questioning in Hanni. When she really wants to know, the questions are incisive and insightful, and while there may be followup questions, it does end eventually.
The other type is random, weird, doesn't make a lot of sense, and tends to be repetitive (e.g. repeated why's). Often she doesn't even listen to one answer before asking the next. These questions give me the distinct impression that she's bored, and is trying to think up questions to get attention.
We have a "why song," and when the questioning gets too annoying I start singing it. ("Why oh why oh why oh why? Why oh why oh why?" Etc.) She gets the point, and we both start laughing.
