I don’t have any children of my own. I remain close to my 2 step children, and their mom, after their dad died suddenly last year.
It has taken a while to shift my mindset from being unhappy I hadn’t had children to being thankful I don’t have children. At 45 I’m enjoying the freedom not having children has given my life now and planning my future plans.

It is not bad not to want children. It is sad if someone who wants children can't have any. Adoption sometimes works.

I have two step children, no biological offspring. I'm good with it.

They're lucky.

I'm childless and I love it

I quite like being childless. There are lots of people who have children, and don't want them, or had a child to "fix" their marriage. I feel terribly for them.

I haven't got any

Not having biological children is doing the rest of us a favour as far as limited resources and pollution go. I consider it selfless these days. They should be rewarded.

Sometimes being childless is a choice. My best friend and her husband have been married 30 yrs and chose not to have children but are a mentor to my daughter and couldn't have more love to give. They chose to live a different life, and it's a beautiful one.

It's their business. Left to myself, I probably wouldn't have either married or had children.

I don't feel positively or negatively for childless people. They are like people with brown hair vs people with blonde hair...just people.

I feel bad because my mom wants grand kids and I don’t want children. She talks about it constantly and it doesn’t help that all of her sisters (7 of them) all have grand kids.

Bringing children into the world is a choice. Not bringing children into the world is a choice. That choice is up to the people involved and it is no one else's business. Too many children are born as a result of not thinking about the consequences of an act. Some of them are fortunate to have parents who, though surprised by the results of their passion, were delighted to have them. Sadly that doesn't happen very often. Sometimes it is an inconvenience for one or the other or perhaps both parents.

There are many possibilities, but I won't outline them all. Speaking to your specific question, yes, it is an issue for the majority of people in the world. It is how the species is preserved, and increasingly it is how numbers of members in various religions are bolstered. At one time it was important because lifespans were short, life was hard, and it was a matter of survival. Those conditions are long gone for most regions of the world. However, this idea that people should have children has carried over and is in force today as it was in centuries past.

The majority of the people in the world make the assumption that everyone should and will have children. This is largely because of the religions of the world, some worse than others, expecting their members to produce children like an assembly line that pumps out more and more obedient carriers of the flame. So, yes, most people think people who don't want children are somehow not normal, whatever that is, and that they need to be convinced to have them. I think this is a wrong mindset. That I think it is wrong does not change it. As in so many other things, it is something we need to outgrow, and I think I see some glimmering of hope that we are in the process of doing that now.

Societal norms (man, I hate those things) do pressure folks to have kids.
.
But have them or not, ain't none of my business.

I believe having, or not having them is a highly personal choice. Society-parts of it- may feel bad about folks choosing to have no kids...but that’s THEIR opinion. And none of their business.
Wouldn’t the world be so much better if we all just minded our own effing business?!

For me having kids was a personal growth experience. Before the kids I was self-focused and self-absorbed. That changed. Suddenly you can't do what you would like to do, there are two are beings to consider and look after. It was the most challenging experience in my life and I'm glad they ended up as good human beings even though both are in their 20's now and I rarely see them.
I've had a few dates with women who never had kids. They were still stuck in the state I was in once.
Now if you choose not to have kids there are plenty of charitable organizations you can get involved in and donate to.

I sort of feel bad for people whom it's clear wished they had them, but that's it. Otoh there are too many people on this spinning ball. I never thought I'd have them myself until hit 30 sooo.
My body was all "fooled ya didn't I? " We haven't spoken since ...

I have no children and l feel great. I haven't seen anything that has made me regret my decision.

Over population is a world wide problem . Why should anyone be belittled , for not having more children . If you don't want them , don't have them .

I allow people to be as they wish.

I feel that they did what was best for them.
Unless you are absolutely certain you want them, you shouldn't have them.

Some people don't want children, and that is their choice -- and mp one else's. It is not for others to judge.

They are less selfish.

My oldest son and his wife decided back when they first met that they didn't want children. I never had a problem with their decision.

Having children is a huge responsibility. If you don't want the life-long commitment, you shouldn't have them.

Sometimes sad. I know a number of the kidless. some of them have accumulated "family" members of all ages. Others are feeling the emptiness.

And knowing some who have children of worthless value wish they were without.

I like idea of the cohabiting approaches: "retirement" homes that are full age range. These are good for those with children as well.
