Last night I put Jack to bed at midnight. He'd had 2 hour-long naps in the day, one in the evening. I was so engrossed in finishing The Game by Neil Strauss that I didn't sleep till almost 2am. He woke at 2.45am, 7.20am, and then once more (I was too buggered to check when).

I had the ioniser on at Medium and then a/c on at Low. May have been my constant moving around that disturbed his sleep.

Let's try again tonight.
