I don't mean to cast any judgments, but be careful, if your wife waits until she is 35, it may be too late for her.
My wife and married when she was 30 and I was 29. After a few years of trying, she decided to get checked out. The doctors determined that she was premenopausal. In other words, it was already too late for her.
I don't mean to scare you, just don't assume that you can wait until a predetermined age to have kids.
So true! It's hard to believe, but fertility DOES start declining rapidly after 30 (maybe before). Many, many professional women assumed they could wait for a long time, only to be severely disappointed. This misinformation is directly behind the massive (relatively) numbers of women seeking fertility treatments.
I see many more young mothers today than I used to at the height of the feminazi "work must work outside the home" frenzy, and they seem to have it so much easier than the older moms. Plus, they get their figures back! :-)
Good thinking. I had not really thought about that since I was born when my mom was 42.
But, that is exceedingly rare, and I recall my gf's mother had early menopause.
I better not wait until 35, just in case.
