First off, what Shagnasty noted: guys have it easier in this regard. You’ve got a LOT of time, if it turns out you need it. You’re 14 years younger than I was when we had our first kid. There seem to be a lot of old new dads everywhere. Yeah, we’ll all be parenting teens when we’re in our late 50’s and paying for college when we’re trying to retire, but still. Children are wonderful things and add joy to your life that you can scarcely imagine. It’s worth it.
There are certainly advantages to having kids at a younger age, too, but I still wouldn’t be in a hurry to get into what you think/hope will be a permanent relationship. You WILL be tied to the mother of your children for a long, long time, even if things go bad. Do not, do not, DO NOT pair up with a functional reproductive system whose owner only sort of does it for you now, or who you can’t see wanting to be with every day for the rest of your life- that’s a recipe for unhappiness. As also noted, the good relationship needs to come first. Toward that end, I’d be sure you’re doing everything you can to find yourself the woman you want to be part of the rest of your life- ask all your friends to set you up when possible, get yourself into groups and activities where you’ll meet people, use personal ads and/or dating services, whatever.
The $$$ aspect has been mentioned, and wisely so. Have you run any numbers on child-raising? Just a few, for starters:
Diapers- 20-25 cents apiece x several per day x 2-3 years, per child
Food- starts at about one dollar per meal x 2-3 meals of solid food per day when the baby begins eating solids, after which the daily cost only goes up. Possibly formula in there, too, which is expensive. Multiplied by every day of the child’s life until he leaves the house, multiplied by every child.
Day care- Figure on high 4-figures (could be more) per year, per child, until school age. Or, the entire salary of a parent who quits to stay home with the children, from the time of quitting until the youngest is school age.
Orthodonture- Often highly desirable, but not technically necessary and thus considered an elective procedure. Meaning, insurance may well not cover it. Several thousand $$$ per kid.
Life insurance- Premiums can run into the 3-figures per month if you want to insure yourself so the kids would be left with the equivalent of your salary until they’re college-age. A lot more if you want the payoff to cover college expenses if you croak early.
etc. Obviously there’s all sorts of significant expense categories I skipped, but you get the idea. Not that finances should be the deciding factor, but if parenthood is something you know you want in your future, it’s a good idea to have a clear-eyed view of what it can cost. Taking a little time to build up savings or otherwise get your financial house in order may be very worthwhile in the long run.
It’s still worth it, though.
