I don’t doubt that some people get hassled about a lack of kids because I’ve experienced some myself. No, it’s not about being over-sensitive (usually), it’s about someone in the majority having no clue about being in the minority (usually).
Having kids is the default and the normal and for many people conforming to society norms and expectations is important. You grow up, get married/have a partner, get a house, get kids… They follow the expectation and it never occurs to them to deviate, or someone doing something different is disturbing to them because it can be interpreted either as rebellion against the norm or defiance.
These days, when the topic comes up I usually say that children didn’t happen for us and we’re OK with that. Most people accept that and move on. Sometimes they don’t, and that’s when it gets annoying.
I have had people insist I can not be happy without giving birth to children of my own because, since I’m a woman, that’s my role/destiny in life. I have had people ask probing and nosey questions about the medical history of both myself and my spouse, and while it usually comes from a benign place it’s unreasonable and prying. I’ve had people try to push adoption on us. I have had people tell me to divorce my spouse “before it’s too late” and find “a man who can give you children”. Much of them time I now find these reactions amusing but yes, if I was more sensitive it could be excruciating. “Sensitivity” has a role in how I react, but it’s not a factor in idiots saying stupid or inappropriate stuff.
But those are exceptions. MOST people understand it’s a private matter and shut the hell up.
Oh, and I never got pressured to have kids by my parents or in-laws - the in-laws because my spouse’s mom knew he couldn’t have kids. My parents because they were pretty firm that people shouldn’t have kids unless they wanted them, they were aware my spouse had medical issues, and my parents were remarkable about to prying into their adult children’s business. Also, my sisters had the grandkids before I got married, so that was never a factor (and I suspect even if they hadn’t my parents still wouldn’t have said anything).
Why don’t people have kids?
- one or both partners can’t for medical reasons
- there might be a genetic risk
- they choose not to have children
Two of those reasons are highly personal and no one’s business outside the couple involved.
I also point out to busy-bodies that I do, in fact, have children in my life, my sisters have offspring so I still have family - I’m not a freakin’ orphan! Any inheritance I leave will be to friends, sisters, and my nieces/nephews rather than to children of my own. I know how to hold a baby, change a diaper, and coo over babies - and no, none of it is painful or dredges up regrets. Yes, I know - no kids and not a sobbing wreck, how shocking! Also, no kids but likes kids - how shocking!
