I made the error of wasting my time (ahem... it was fun while it lasted, at least) not having a kid until I turned 49... which meant our parents were too elderly (or dead) to help (my mom had me at 35) in any significant capacity, and the rest of my relatives (as it just so happened) already had plans to move away to FL before he was conceived.
This has resulted in so much stress (especially in the 3's and 4's, because he still doesn't sleep through the night in his own goddamn bed) that I arguably lost a job from it... 50+ year old bodies are simply not well-capable of handling toddlers for the more-than-fulltime-weekly hours that they require
I'm sure there are fringe benefits though but damn
I don't think child rearing is supposed to be as difficult as modern society makes it.
As you pointed out, you don't have a lot of help in raising your kid. You're expected to do it mostly with your partner (or god forbid alone).
They've done some studies of hunter gather tribes to determine who handled babies the most. Turns out the kids' actual parents only handled the kids for about half the time (I think even a little less)! The term for it is "alloparenting".
Evolution did not prime us for this level of child care. Good luck to you!
