It occurred to me, that like most threads, the topic wandered a bit (until the last guy who remembered). I was perhaps more guilty than others.
"Partner commits to another partner with kids." Would you do it?
I don't think a poll serves any useful purpose. People aren't polls, people are people.
In the 50's, there was something WRONG with a man if he didn't have a homemaker wife dressed like Beaver Cleaver's mom and 2.5 kids. A man's career could not be expected to advance unless he fit that pattern. Many families had kids ... that shouldn't have.
Thankfully, today, it's simply not an issue. If a hiring person asked you about your family structure, you might be able to sue.
The point is: there are some people that just don't want to be parents. Thank goodness they don't need to be any more. A good parent starts with someone who really, really wants kids. Someone who kinda thinks that maybe they want kids shouldn't start making babies. They should ache for it.
On the other end of the spectrum, there was some Washington politico in the news about a month ago. As a side issue, people who were criticizing him were startled to find out he & his wife had adopted 11 children over the years. I love kids. I couldn't do that. My hands were full with two.
There's all kinds of people in between.
There's people who love kids and don't care whose they are. There's people that NEED that biologic connection, or there wouldn't be fertility clinics and surrogate mothers. There may be a shortage of adoptable WHITE babies, but there's plenty of kids looking for parents ... no stretch marks.
I can only see this in a personal context. If my two kids were still young and I was thinking about committing to a partner, I wouldn't commit until I was absolutely sure what the relationship between the partner & my kids would be. I know people hate Dr. Laura, but she has kernels of very good advice. At the beginning of a relationship, people are "nice" to each other: it takes about 1 1/2 to 2 yrs for people to start acting normal ... what they're REALLY like, what really ticks them off, "I hate that thing you do", etc. I wouldn't commit for two years, and then I'd just have to cut the cord if it was clear my partner wasn't going to be a good parent. That's a lot to ask: 2 yrs of investment ... but my kids would be at stake.
The absolute last thing I would want to do is constantly wedge myself between my partner and my kids ... just so I would have someone. Kids are a handful as it is. You don't need to add a partner that you have to "deal with" as well.
I had kids with serious medical problems. You need united parents for stuff like that, otherwise going it on your own is much less stressful and better for the kids. I've had it both ways.
