I just had my first at 36. I felt ready to have kids from about age 30, though in retrospect my career has taken some pretty decent leaps in the last 5-6 years so I have benefitted from waiting there. We didn't have any trouble conceiving or with my pregnancy, so no regrets in that regard.
My OH is 48 and sometimes I wish he were younger because of the concern of him having less time with the kid/s. He will be retired by the time LO goes to university. But on the other hand, he is in great shape and has the energy of a much younger man, so it's not too much of a big deal. My dad's parents had him young and yet he was orphaned by the time he was 14, so you never really know how life is going to pan out. Also, my OH has a very well established business, so financially we are in a very comfortable position that we wouldn't have been 10 or 15 years ago.
