PQotW: Despondent or jaded?

I thought I'd start a new feature, the Philosophical Question of the Week. I'll give it its own little sidebar, so it'll go up and then you can click through to see it even when it disappears off the front page.

This week's question is:

Which is worse,

a) when your first child is going through a horrible phase (usually sleep-related) and you feel hopeless and despondent thinking it'll never end, or

b) when your second or subsequent child is going through the same kind of horrible phase and you have absolutely no sympathy because you know it's only a phase and you have no patience and just wish the kid would move through it already?
