+1 million on sleep being the biggest issue you'll face. My daughter just turned 2(!) and she's been sleeping 9-10 hours a night for a good long while now, but it took about a year and a half for my IQ to get back up to something approaching what it was before I became a papa. Totally worthwhile to hear her say things like "I want cheese on my mat" or "all of the trains went bye-bye" or "that fell on papa's head" or "I'm a robot monkey", though.

OT to Ez: Welcome to Portland! There's a fairly active Ruby community here, embedded in an extremely active tech community: see calagator.org if you haven't already. I'm happy to share what little I know about parenting in Portland (geeksam at gmail).
