A ball going through a tunnel

Gus, looking at a picture of Saturn with rings: "A ball! Going through a tunnel!"

Jasper, at bedtime, after I lay him down and sing twinkle twinkle little star: "I'm going to tell myself some more stories now."

Gus, at bedtime, after he's been put to bed, he lays there for about 10 minutes talking to himself, then we hear (on the monitor), him singing to himself, "Twinkle, Twinkle, Little Star..." and silence after that, as he actually sings himself his own bedtime song and puts himself to sleep!
