In fact here's something I wrote in my journal when he was 3y9m:
Ha! That's exactly like Hanni! We've been reading a book called How To Dig A Hole To The Other Side Of The World.
-Why does the digging get harder? Sand is easy to dig.
-Why does the friend need to pull the dirt out in a bucket?
-Why should you save bones that you find?
-Why is she using a drilling machine? Kids aren't really allowed to use that kind of machine, are they?
-Why is she wearing a diving suit? Is that water? Why is it brown? Is it ewwy?
-Is she going to snuggle up to the rocks because they're warm?
-What's a geyser? Did she get shot out of the geyser?
-Why can't she keep digging in the same hole where the geyser is?
-Is she in the volcano? Is she going to get shot out of the volcano?
-Is her submarine going to burn up? If it burns up, will she be in the hot magma?
-Why do they call it the "inner core" and the "outer core"?
And so on. And so on. And so on.
