Conversations with Kasper

Kasper: I did it! I slid on my belly!
Dada: You have a belly? Really? Let me see it!
Kasper: [points to bellybutton] It's right here. It has a hole.
Dada: What do we call that hole?
Kasper: It's a hole. In my belly.
Dada: But what do we call it? [pointing to my bellybutton] What's this?
Kasper: That's a big belly.
