So! something that's NOT about a medical procedure then...
Anxiety is something I suspect all first-time parents go through. And hey, possibly second, third and fourth time parents? Not that I'm anxious all the time - far from it. In fact, probably during my waking hours, I don't think too much about baby-related things (blog posts aside).
Sleeping is a different matter. I don't baby-dream every night - but often enough, and they're never positive. Baby not feeding, baby rejecting, baby being miscarried, all similar types. You don't have to be a rocket scientist to work out the whys and wherefores.
I just wish I has a positive dream once in a while, y'know?
