Just how sleepy is Joshua?

Most of you know that Joshua has had his nights and days mixed up. As a result, daily it has been a battle, a real challenge, a frustrating dilema to try to keep him awake for periods of time so that he will sleep at night. Just how sleepy is he: He's slept through diaper changes- common. He's slept while eating- common, and I wonder if this means he'll be a midnight snacker as an adult. He sleeps through being wiped down with cool wash cloths- a bit surprising. However, this tops it: He slept through his bath. I mean not a single eye lid flutter! Now that takes sleepy determination. And this is what I'm up against. Since babies don't do much, I thought this was a noteworthy story for one so little.
