I have been waiting two years since baby fever hit (my twin sister had her first - the spark that lit a bonfire, ha ha), and likely have another year or two to wait.
Mostly it has been my OH's reluctance, I probably would have had a baby in our less than perfect circumstances (I'm in grad school, he doesn't make a whole lot). Slowly, slowly, he is getting comfortable with the idea.
He just got a new job that makes a bit more, actually, so I'm hoping that helps! So far, he has been more of a 'check list' kind of guy, reluctant because he still has some debt, we don't have a car, etc. etc., but it's hard to know if ticking them off would help, it might be more emotional.
At any rate, just thinking it is somewhat more plausible that we could be trying in a year is pretty exciting! (Even if probably not.)
