What's remarkable to me is how content both those with and those without children seem to be with their respective choices. (I know, a massive generalization, from purely anecdotal evidence.)
Disclaimer: in my 20s, with no kids... yet
On the other hand, some of them might not and I sure as hell don't want them having kids. How miserable for everyone involved.
I feel fairly confident in my opinion that there is always something worthwhile to spend money on.
Furthermore, just on the basis of the number of single mothers I know, I would posit that at least one man you know has kids, regretted it, left the mother and just hasn't volunteered that information to you.
[edit] Also, my wife was adopted when her parents were in their 40s, so it's probably not too late to raise a kid.
The hard part is that parenthood changes people in ways that go beyond life experience. There are actual, measurable physiological changes that happen to parents. In many ways, children are like a drug to their parents. Just like addicts will sacrifice much of their lives to their habits, so too will parents sacrifice much of their lives to their children.
So asking your question is like asking whether a drug addicts wants another hit. That person will undoubtedly want one, but the person that person was before their addiction might look at the reality of the situation and decide they didn't want to start the habit in the first place. Likewise, someone not 'under the influence' of their parenthood might look on the situation differently.
But, in both cases, it's impossible for someone to understand both sides of the choice simultaneously.
Besides, regrets tend to come in the form of "wish I've done something" (this applies to both sides), as can be seen even in earlier comments of this chain. Regret of having kids is likely to manifest in the form of wishing to have done more/ different things.
But to follow on my other comment above, I also have a pretty clear idea that I gave up some things to become a parent. And I think people who skip having a kid, and then feel doubts later in life about that decision, are really just feeling the other side of that coin.
We're in our late 40's / early 50's.
I don't find this surprising at all. Generally speaking, people make these choices because they know in their heart that it is what they want for themselves.
There are moments when I wish I didn't have kids.
But then there are moments when I see my son's or daughter's face and am in utter awe at their amazing beauty and realize a kind of happiness I can never imagine having from anything else.
When I sum it all up, I think that I am better and happier with them in my life than I would be if I didn't have them.
In the end, having children is the only thing in life that really makes any sense.
Is it a given that magnifying life's amplitudes is a good thing?
You're giving me hope I still have time!!!
Yes, if your wife/girlfriend is around 35, the window is starting to close, but more and more women are having kids well into their 30's and early 40's.
What I have become, is two things - more aware of time, and how limited it is. Second, selfish with my time. I do what I want to do, and no longer do what my girlfriend or anyone else wants me to do, unless it aligns with what I want to do.
