Lots of good advice here. Think hard on this before you commit. Here’s my story.
I was about 33 when my son was born - my wife was about 32. The pregnancy was hard on her, although she has never had what you might call robust health. She has had many minor health issues over the years, and one or two that were medium to major, requiring surgery. I can’t say if the pregnancy aggravated this or not, though.
Young Ralf was a joy to have. He was a healthy baby, never had anything worse than colds and such. He was a good kid, too - not a problem child, misbehaving, doing drugs, etc. He was smart - did good in school, was in marching band, became the drum major his senior year. He’s got an amazing singing voice that didn’t come from either one of us, and a talent for acting as well. He was in several high school musicals, considered going into theater professionally for awhile, and is active in a community theater program. He’s 20 now, in college, and doing great. It’s amazing to see how far that little grub-like creature I met 20 years ago has changed and grown, and I can’t wait for the next 20.
At 33, I knew we would most likely have only one child. The expense of a a kid 20 years ago floored me. Day care, clothes, food, diapers… We got through it, but it was a tight squeak now and then. We’re comfortably well off now, but it took a long time to get here.
Others have mentioned a lot of things you need to consider. The increased risk of birth defects; the increased risk to the mother’s life and health; the added cost, in terms of dollars, time, and lost opportunities; your wife may have to put her career into a holding pattern for a few years; you two will almost certainly be mistaken for the grandparents, not parents. In most get-togethers with other parents - school functions, scouts, sports, you will stand out.
My gut reaction to all of this is, if you’re burning to have a kid, and that will fulfill your lives, go for it. You’ll work hard, but there is nothing like having your own child crawl into your lap, give you a kiss with lips still coated with peanut butter and jelly, and fall asleep in your arms.
If you are happy with your life now, and you’re just wondering if you’ve missed out on something, then think hard before you do this. Once you’ve got them, kids are almost always great. The human brain is hardwired to think that; otherwise we’d probably drown our young. But if you’re happy now, and you’re stable in your life and your relationship, odds are you will be for the rest of your life. Why upset the applecart?
