The Boy Who Doesn't Sleep

Kieran has been convinced for quite some time that he doesn't sleep. Whenever the topic comes up he tells us that he stays awake all night, just like an owl. Given his playful nature (and the fact that he takes after his goofy dad in creative story telling), at first I though he was intentionally being playful. However, clearly he is not just playing and is firmly convinced that he DOES NOT SLEEP. Now occasionally he admits to closing his eyes, but that never, ever results in actual slumber. Maranda commented that it makes sense really, from a four year old perspective. I mean, you are never conscious of being asleep, right? Yet, I still find it quite funny that every night when I wish him a good sleep he says "don't worry, I won't sleep" with complete certitude.
