I know someone who's kid committed suicide. I know people who's kids turned out not the way they had hoped and they don't speak anymore.
A longtime neighbor had a few kids, but really unfortunately luck. One committed suicide (He had bipolar disorder) about 10-15 years ago and his daughter was murdered just a few months ago. I can't imagine what that has to be like to have two significant losses like that as parents.
Bipolar disorder is no joke, though. My brother has it and growing up with him was extremely difficult. My parents struggled with my brothers mental health for so many years... He was destructive, abusive, couldn’t keep a job, got into hard drugs, many suicide attempts, etc… It was bonkers. Thankfully he eventually got his meds sorted out with his doctor and things start going good for him. He has been mentally stable for probably 10 years or more now. Night and day difference from what I grew up with. But thankfully, he has been on the right track and doing very well for himself as an adult. For a few years, I really didn’t expect to have a brother much longer when I was growing up.
So between my own personal experience, the people around me don’t help the case either… One coworker had a son a year ago (their second) that they had found out was born deaf a few months later, so by the time their son was one, had undergone two surgeries to put in cochlear implants. Hearing his stresses of surgery, insurance, treatments, and all the post-care… Oof. Not to mention, prior to his second son, his general regret and discussing having literally no time for himself anymore and all those standard parent compromises… He didn’t do so well with that.
My project manager has a child with downs syndrome, which sounds quite challenging when he has talked about it.
A friend in Florida had their first child about 14 years ago who ended up having pretty severe autism, which has been very difficult/stressful for them as expected. But they do try to get their son the best chance at being an independent adult. Many school changes for the best care, doctors, etc… But the meltdowns and all that are still prominent and is very stressful for them. As terrible as it sounds, I absolutely get the impression they wished they didn’t do the kid thing (they did later in life, late 30’s early 40’s I believe) because of general comments about being held back from travel or this or that because of their child. It’s sad, but I mean, you signed up for it… Good or bad.
On the flipside, I know of happy families as well of course… It’s not all doom and gloom, but I will admit I hear/experience more of that than the good. My cousins have a large family and seem to LOVE being parents and their kids, which are all getting into sports and kind of "repeating" their own childhood of course. So that gets them excited. I have a few friends with large families that seem straight out of a sitcom (foreign to me!) in terms of well behaved, great kids. So it certainly goes both ways.
At the end of the day, you either have to be up for the challenge or not... Will probably be the highest highs and lowest lows you will ever deal with as a parent. Having a good partner is huge, too. Make sure you are on the same page and have the same goals in mind for care and all that. Be a stable, loving home… If you can’t offer that, honestly don’t bother.
For me, though, I will stick to having dogs as my spoiled kids... ! But if one day my SO seriously approached me and really wanted kids, I would likely be on board (but maybe the adoption route, instead). But she is more against kids than I am in general, so I don't see that happening
