DS is a high energy kid, so he's usually fine after a night or 2 of missing a couple hours of sleep. At that point, we put him in bed REALLY early and threaten to take away his books and/or his computer time. DH for some reason usually wakes up and finds him first if he's up in the middle of the night! So I usually get to miss the whole episode.
He's actually much easier than DD3 in terms of sleeping, even though he's become a bit of a night owl. That one is still driving us crazy.
The Buddha manga series is very good. DH actually bought the series for me a couple years ago. I've done a lot of reading on eastern religion/philosophy. And DH loves good manga! So whether it's really for him or me is a mystery.
