I think I would really like to have kids, except most ppl with kids seem to have an unhappier life, no free time, much higher stress, and a worse relationship with their partner. That's a scary thing to willingly enter into.
money -- enough to buy back time via meal plans, no job, and nannies if desired
We're in this scenario now (minus money + no job), def higher stress and less time, but still spending time w/ friends and loving parenthood
As ortho and lots of others have said, au pairs! I grew up w them until I was ~12 and my parents seem/seemed much happier than my peers, and my adult relationship w them today is way better than most peers' as well.
Living with / near friends who also have kids as a pseudo family
Au pairs / nannies if you can't have that
1 kid requires the attention of atleast 2 adults, but it scales really well.
