I like my sleep, used to get a lot more, but with a six month old son, I now get a lot less. That's why I'm sitting here at 7:30 in the morning typing this instead of catching up on my sleep after a fraught few days of flying.
To be fair, he's not a bad sleeper as babies go, but as I'm sure all parents know you tend to wake up if he sighs and turns over never mind cry.
I find I sleep a lot more when my life is less than interesting. There is not real point in waking up if your life is dull. It's sure not dull lately.
